Some of the custom made SONY ICs can be sourced for repairing the walkmans. But I'll give a simple example, the notorious CX20084 used in many...
I do remember the gigahertz race with CPUs. That is a much more complex matter, as the specific arhitecture of the CPU will matter to a...
I undertand what you are stating and I agree: doing measurements is not important for the end user. And he/she shouldn't need to do any...
I agree with the fact the a particular device should sound good to the ears of the listener. But at the same time, meeasurements (being it...
I think unless a frequency response measurement is done on both Groove and MegaBass, a clear answer would be harder to find as not all technical...
The DD11 service manual specifies a wow&flutter of 0.15% WRMS. Given the similarity between DD1, DD10 and DD11, I can assume there could not be a...
From the genealogy perspective, it should be there because it is clearly related. I didn't say to remove it, just stating that in real life, it...
