i knew it. my wm-d3 is what i always use to record tapes. even with the ticking the sound is the best i have by a good amount. i paid 20+ dollars and haven't done a thing to it except a good cleaning.
Now I have had many Panasonics, including the SX91 and some others mentioned here and there is no way they can sound as good as a Sony DD machine, certainly not the D3 or DC2. The SX91 sounds okay with highly-sensitive earphones but anything more than that would be an overstatement. Actually, the 91 was sharper sounding than the cheaper 71 model which made it very fatiguing. The S80 was a much better machine though just by looking at the features and specs.

Thank you very much!
That is to say, better Sony WM-D6С not?And this ultimate, without any chances for others?
But if on order of the rating? What models?
I think DC2+"DOL" is best!
Hello,
What is the DOL ?? Im not real educated with all the models. Thanks, Ray
I really like the sound quality of my Aiwa HS-G09.
With the 5-band graphic equalizer and my Sony "over the ear" headphones...awesome. Of course this can only be accomplished if the cassette is recorded correctly.
Hello All,
Has anyone here compared any of your favorites to a properly calibrated, and serviced Sony WM-D6C?? I have a Sony WM-D6C that has been recently serviced and calibrated, new belt and all, including Biased for TDK SA Tapes....I had all this work done by PRO-DIGITAL in Broomall,PA. They specialize in the Sony WM-D6C among others, and even stock some parts for them. They are now more into the Digital Units, but still do all work on WM-D6C. I own several other great sounding walkmans, by Sony, and other manufacturers....but I find that the Professional Sony WM-D6C to be the very best sounding of them all. This Walkman, the WM-D6C was also favorably reviewed by Stereophile and the Absolute Sound Magazines, which says alot. They normally only deal with audiophile type devices. They actually compare the WM-D6C to some of the best Standalone Home Unit Cassette Decks. That is a huge accomplishment. But I also say the deck must be adjusted to factory specs or better, and the tapes and headphones must be of the same quality. Ray
WM-D6C, is one of the best sounding, then some of the aiwa's sound very good, but have to change the capacitors on the aiwa's for them to sound any good due to aging of the capacitors.

After finally solved all the problems that plague the players (such as the breaking of the gear, caused by the expansion of the metal inside, with regard to the wm-dc2) and bringing them to their full capacity, reducing the wow & flutter, improving the azimuth, (creating a double adjustment for azimuth to wm-dd9 ), improving the level of output and so on. The best one was the wm-dd9 closely followed by the WM-D6C, the third wm-dc2. The tapes were recorded with Dolby C from WM-D6C as player takes the second place. As a source directly connected to the WM-D6C, with the highest quality cables, has been used dvd changer Denon A11. It 'goes without saying that the tapes have played better than the original CD. How to listen without the vinyl crackles and pops. All other walkman with dolby c I've perfected and tested (aiwa hs-px303, px505, jx3000 and others follow with the third place with a nice posting. Final Standings for me I love the Dolby C, after careful and extended plays with headphones Grado SR-325i: 1-wm-dd9 (TOP OF THE TOP if modified and if properly calibrated). 2-WM-D6C (top of the top as recorder, if suitably modified and calibrated bear comparison even with the best Nakamichi). 3-wm-dc2 (if it solves, with a proper repair gear that breaks often, and perform some modifications) sounds so wonderful. The others are just walkman.
dottor walkman I think you need to do your test again, the DD9 is not better than D6C or DC2.
Sony WM-DD9 is like a Nakamichi Dragon in the fact that both companies have loaded these machines with all the tech they know of at the time. Just because the machines are loaded with tech does not make them the best sounding, which they are not.
As good as the DD9 may sound when I listen to it next to DC2 it sounds thin and anaemic. When put next to D6C it’s like putting a featherweight in the ring with a heavyweight, D6C will crush the DD9.
Nakamichi Dragon Vs CR7 the CR7 wins every time.
Dotter Walkman, I respect someone who can navigate such treacherous waters with such confidence.
We'd be intrigued to know what equipment you're using to make these assessments? Are you measuring full THD, Frequency Response and Signal to noise ratio or are you relying on your ears alone?
Dotter, that does sound Icelandic!
I don't think that the DD9 jas the potential to drive the Grados to their fullest potential (and I am not talking about the volume here). Though they are reasonable sensitive at 96dB/mw and are low impedance at 32ohm, the DD9 would still not be suitable to drive them properly due to the higher output impedance of the player and more importantly, the inability to sustain a flat response at different volume settings. Considering this applies to most audio amplifiers (not just in the sense of portable audio), it is unlikely for one pair of headphones to work perfectly at all volume settings and on every player. So if you find the optimal player/headphones combo and then change a player, it's a completely different story. Considering the amplifier sections of the DD9 and DC2 are completely different so comparing them would be very difficult, even if you set the output on both players to exact same volume on those headphones.
dottor.walkman - 2010-10-03 13:14
I'm sorry that you think so. The wm-dd9 has the potential that clearly you not know. I explained that certain modifications and calibrations are performed. Although its power output is only 5 mw against 20mw of dc2 and 30mw of D6C, are enough to drive very well the Grado. Now I only use the SR-325th with my dd9. As for sound quality, the dd9 has a wider frequency response and linear of the D6C and of the dc2. I do not trust only of my ears and those of dozens of other audiophiles, but also of the oscilloscopes of my laboratory. Not to mention its much more accurate and robust construction of dc2 but also a little better than D6C. I have repair and modified many dd9 and now I know how my pockets. For example has all the resistor in metal glass, and, except for two electrolytic capacitors, all others are tantalum. I have disassembled, repaired and modified hundred D6C and fifty dc2 and I can say with confidence that the electronic and mechanical components of dd9 is the best. After the appropriate modified, if used correctly, does not break more and never problems for ever. Is an object that has the flavor of the miracle.
dottor.walkman - 2010-10-03 13:40
I still want to add that my technique is a finding supported by laboratory instruments. However I have the utmost respect for your ideas and beliefs. Besides, in my collection I have six wm-D6C, three wm-dc2 , two DD100 bood khan, three wm-d3 and more, are devices that I love. I have a friend who has the Nakamichi Dragon, RX 505, and CR7 zx9, so I could do a lot of respect. I then try to give my contribution, in my experience, in this wonderful forum. I'm not going to impose my ideas.
Hi Dottor Walkman!
No look here, no one is putting you down. And if you managed to modify the DD9 to make it sound as good as you say, then we would like to know more about it. You can post some pictures of the things that you have modified as we are not just collectors here, we value insight into technology that is behind it so feel free to make your contribution. Oh and welcome to the forums!
Hi dottor walkman it’s interesting what you say you have done to the DD9 to make it sound better, it would be nice to know what you have done like Tuna said. I have ideas on how to make the DC2 sound better but I do not have the expertise to do the work. So please let us all in on what you have done to the DD9.
Some people do look at lab figures and some equipments do have better lab results then others but when it comes to real world listening test they don’t translate. I used the Nakamichi analogy as I’ve done listening test with friends. I have CR7 and my friend has a Dragon and 1000ZXL. On paper the Dragon has better specs but on listening tests the Dragon came last in the test, the winner being 1000ZXL.
I use to own NuForce Reference 9SE V2 (correction still do but will be giving them to a friend for Christmas) the NuForce fans are always saying about the damping factor being 4000+ and most power amps are measured in the hundreds. These people state it has better control of the speaker’s maybe, maybe not. I have just switched to Spectral powers and it just leaves the NuForce way behind. So what I’m trying to say is lab results and paper specs mean nothing if it does not sound at good in the listening test, which is what matters to me anyway.
dottor.walkman - 2010-10-03 16:01
Thank you for your welcome. It 'a long time I was looking for collectors and lovers of analog walkman with whom to share ideas and experiences. To explain what changes I made to the Walkman we're talking about, I must first tell you something about me and my work. I have done for many years the blacksmith mechanic also working on high security locks. Same time, I developed a passion for electronics and micromechanics. The first Walkman that I bought and 'was the bood Khan in 1987. Because of the defects introduced almost immediately to drive because of the support of the pinch roller, I took him to the service center. Not only were unable to repair it but created other problems, apart from some scratches. Because I'm very picky and I do not like the scratches, I decided from that moment that I'd repaired my equipment. In that case remade with my hands a new medium for the pinch roller brass instead of iron as was the original. It worked perfectly and was even more beautiful to see. That was my first experience. Since then I have done many repairs and modifications to hifi equipment for many audiophiles. As for the wm-dd9, is an excellent machine that only needs some changes then I will tell you. Same thing for the WM-D6C. As for the wm-dc2 you can not do much except improve the wow and flutter, the azimuth, and, most definitely solve the problem of gear that breaks.
dottor.walkman - 2010-10-03 16:09
For photos you have to have a little patience, it's just that they are on the internet and I'm still organizing. As soon as I bought a camera will show you something. I also want to show some pieces from my collection. Now where I am is the one in the morning and I'm going to sleep. Certainly continue to respond tomorrow. Good night.
dottor.walkman - 2010-10-04 03:10
Hello, what changes would you like to know you first. On the dd9 on the D6C or on the dc2?
If DD9 was the one you got the best results from after tweaking, then can you please start with that one?
Thanks
dottor.walkman - 2010-10-04 07:22
First, I apologize, but I have to explain to you a few questions. You can reply you Chris, if you is fine, since you have shown to have very clear ideas and seem to fast technical training. 1 - In your opinion, what are the limits that has dd9 than, say, the dc2? 2-did you notice any dd9 never plays the same way as in REV and in FWD? In your opinion, why? 3-You know that the dd9 has not problem gear that opens like the other wm-dd? 4-Do you know that even the dd9 has a mechanical problem that occurs only after heavy use? Before I say as I have done to solve these problems, I want to see your answers to see how far you have used the dd9 and if you found some other problem. In my next response will explain what I did in the following steps: 1-Remove the capstans and select their positions even according to the rubber rings. 2- disassembled and assembled the motors, reset WOW & FLUTTER and speed. 3-Check the position of head in PLAY and readjust the value of TILT. 4 - Change the bottom of the head to add the ability to adjust the double-azimuth. 5- Remove the pinch roller and put them back in a way that I will explain later. 6-Add SMD resistor whose value will be calculated individually for each dd9 to eliminate the tolerances on the output of the head. 7- Reset the output level to the highest value possible, while remaining prudent under the distortion. All these steps must be explained individually, to perform well need an oscilloscope, a function generator, a wow and flutter meter, a frequency meter and, more importantly, an excellent manual skills, especially in operations on the head and motors, to avoid trouble. Chris waiting for your response and then continue.
1. Lacking adequate power to drive most of its components 1.5V is not enough yes I know its an efficient unit the DC2 has more power at it’s disposal, having auto reverse (therefore Azimuth error) to name 2.
2. Yes the DD9 is different while playing in the FWD & REV direction. The strange thing is that on my DD9 anyway the REV direction is better than the FWD direction of play. I say strange as the FWD direction should be better. Why is this you asked? Since the first thing you notice is the high frequency is not all there and the next thing I noticed is that all the other frequency’s are not that well defined. I can only put this down to Azimuth error. I and most people would have thought the Azimuth for the FWD direction should be correct and the REV side being slightly off, but in mine it’s the other way round.
3. Yes i do know. I have to say I do not work on the DD9, I work on the DC2 as it’s a much simpler unit to tinker with.
4. No I did not know that, as the DC2 is my Walkman of choice. I use the DC2 daily on my commute to and from work.

Hello Chris, before going on to explain the point 1 of technical changes to the wm-dd9, let me tell you an anecdote. A friend of mine, a radio technician like me but not micromechanical, bought a new car with a nice stereo system. He listens to CDs in the car but I saw that he was not satisfied because it kept changing constantly EQ curves without being happy. The advice to turn off the equalizer, but the sound was even worse. Then I connect my dd9 at its plant in the car with the equalizer off. From that moment my friend did not say anything negative on my walkman. In fact, I often ask to bring my dd9 in the car with him.
dottor.walkman - 2010-10-05 01:06
So Chris, I promise you that if you perform the technical changes which I'll explain in a perfect pass from dc2 to dd9 as I did. Even I, after the boodo khan, I bought the WM-DC2 in 1988. I liked very much, but since I love the auto-reverse and I did not like models such as the wm-701c to listen, but only for collection, because it is the belt drive has a high wow and flutter, I dreamed a walkman like dc2 but twice. That is, with two direct drive motors and use only one battery as the wm-701c, because when using two rechargeable batterys is always discharged before the other, while one battery that does not matter. It 'was as if the engineers at Sony I had read my mind. Unfortunately I have had my first dd9 in 2006. It 'was the best day of my life. Now I have several. We will address items 1 and 2 that serve to further lower the wow and flutter and take it to the same value for both directions. Items 1 and 2 also serve to bring the same speed for both directions and equal to the plate that is used for recording. (In my case I changed D6C is the pump flow rate dd9. If you register a frequency of 3000 Hz with the D6C, the 3000Hz the dd9 law perfectly. While originally if the d6c law the 3000Hz dd9 reads about 2996hz in FF and about 2994hz in REW. After disassembl completely dd9 (Be careful that all the screws are of different lengths and flat cable. The spare parts are expensive, such as a screw and costs up to EURO 5). You have to remove the engines from their homes and withdraw support from the capstan FG. Now you have to weigh it with a digital sling goldsmith. Their weight must be 5.5 grams. In the latest modern dd9 weighs 5.4 grams. This does not matter, the important thing is to have the exactly the same weight. You can help each other by exchanging rings made of rubber. only a few times it was necessary to replace one of the capstan in order to achieve the exact same weight. Then you can put in the capstan FG without lubrication. Sintered brass bushings, and when heating oil release. Tell me if you clear up to this point or if I have not explained well and on what.
Hi dottor walkman check your private messages.
Thanks
Chris
What Dc2 + DOL ( Dynamiyc Optimum Loudness ) ???
DOL you can find only in BOODO KHAN.
I think the best Walkman Sound is
Sony WM DD II with Koss Porta Pro Headphones
dottor.walkman - 2010-10-07 01:33
I did a listening comparison between the bood khan with DOL ON and the dd9 with MEGA BASS MAX. I used the same headset bood Khan. The dd9 comes a little further down on the frequency response. The bass is a bit more powerful. I did the same test connecting to an amplifier with the volume of the two Walkman headphones on level 6. The bood Khan has the volume a little higher. The dd9 has the bass a little bit stronger and the more analytical sound.
I have to admit I have never tried a Boodo Khan so cannot comment on it sound quality.
I have to say I have never heard any Sony Walkman that has bass boost sound good with the bass boost on. They all sound terrible and artificial, at the moment I have DD9 and DD33 the bass boost is best left off.
The only bass boost that I have had / heard in the past that sounded vaguely good is the Aiwa DSL (Dynamic Super Loudness) system, if used with the BBE system it’s even better.

Not true at all, 4-track heads WILL NOT have azimuth errors if one side of the head is at 90 degrees. Therefore, you should adjust to 90. ONLY rotating heads WILL have azimuth errors.

You need to ask dottor walkman as he can explain more about the Azimuth.
When I did send him my DD9 for upgrade and service, he did notice that the Azimuth was indeed off on the forward direction and closer to correct on the reverse side, like I said it was. I detected this with my ears, dottor walkman’s lab gear showed this to be true.

Very true toocool, the 7 and 1000ZXL are better sounding than the Dragon. I would also say the ZX-9 is better as well. It's not that the Dragon is a bad machine, far from it. It's just that the others have a level of performance that puts them in a category of their own. I'm no expert on Walkman's but I have used a WM-6C. In my opinion it comes very close to that category of excellence!

From my own opinion you are correct about the Dragon not being a bad machine, it is just over hyped and usually from people who have never heard one.
It’s one of those stories that goes round and before you know it, it’s true because it’s been going round so long that know one knows the truth anymore. Almost like the Linn LP12 story, which may have been true in the 70’s.
I own an LP-12 and it sounds great when set up properly. However, like a classic car it needs a lot of attention to keep it on top form. Linn have modified the Sondek over the years in attempt to remain ahead of the game in terms of performance, mine has had some of these mods, most have proven to be worthwhile. However I am out of touch with modern turntables (having been satisfied with my second hand Linn.) In my opinion there were turntables that equaled it's performance back in the 80's so I would have thought that with modern materials and manufacturing techniques the the old Sondek is facing stiff competition now! I still love it though! Anyway sorry to push the thread off topic!! 
Pushing things back on topic; how does the old Sony WM-7 rate in the overall sound quality stakes when it comes to Walkman's. I have one that is on my long list of restoration jobs. I am not expecting it to be one of the best but just wondered how it rated.
Yes Seb968 I know the LP12 needs constant attention to keep it sound at it’s best, my friend has one.
In about 1984 when the Roksan Xerses came out, it just left the LP12 way behind.
I think a full spec LP12 is now about £10000 or the limited one about £25000, I can do much better at half the price of the £10000 one.
I have never heard the WM-7 so I don’t know how good it is.
And no disrespect to you tocool my friend i KNOW you love your d6c's like me and my m90's so big respect there my friend......the d6c last for eons on a single set of batts unlike the dd9 that trowsers a single battery...and the stability of the d6c is like no other deck i have ever owned...i just found her to big haha....all the same a fantastic walkman built like no other

Those walkmans that have the head mounted on the door would flex in and out every time they would become opened and closed. Perhaps they could knock themselves slightly out of alignment. Most likely head wear more on FWD side.

That is a good point Lapis. A lack of mechanical rigidity and robustness can prove be bad news when it comes to alignment and head longevity! This is one of the areas where build quality really counts!

If you have handled a DD9 then you would know this thing is very robust and built like a tank, for the head to have moved like you suggested you would have had to drop it from a great height.
It seems like when as shown in the video, a test of the operation also kicked the head up and down, as well as FWD and REV play also could possibly kicked it out of alignment a little bit. Definitely not as bad as rotating heads would kick the head though.

Even though the outside is very robust, the mechanism can still go out of alignment caused by slight unnecessary movement of the head, like operation, fwd and rev play (not because of the head attached to the door). You have to watch the video again as shown of the movement.
http://www.youtube.com/watch?v=VBnMBbgpysQ
It will still not be as worse as a rotary head.
I guess I didn't do too badly when I bought my second hand one back in the 90's!
