Here are the Sony discman of some high end models from the late 80's and early 90's. Personally I prefer the discman from the 80's for its design and built..they really look classical and sturdy. This video shows some of my Sony discman collection which I got from the ebay.  Which one of these produce the best sound quality?..perhaps you tell me....

Thanks ken80s I just uploaded the video to clips. 

Great Video and SOUND !  Totally in love with the Z555 the best portable period.  

What model is your JVC player in the background ???   DID you know its in a movie prominently shown closing and starting.   Check out "I Robot" at time mark 1.02.16

Hi John, the JVC player in the background is a mini component system model FS-SD9. Excellent sounding in room environment. I'm using it a lot as an external input for Mp3, Discman, MD walkman etc..

 You said it all right there Ken80s

The Early Sony's were masterpieces of engineering, when quality meant something. That 555 is gorgeous and it's sound is

For those who really knows how to appreciate these gems, they willing to pay high price for possession. Take a look at this...
