The mods on that site are good. I like the idea of using coax for the digital signals, but I don't want my player to look like that! Maybe if I run into very thin coax some day, I will do that mod.

Hm, I wish it were that simple....
You would want to keep the top trace, cause that runs to the +/-12V groundpoint

.
All the local groundpoints are also connected through the top-layer groundplane. Not bad, but they should have designed a real double-sided PCB. That would have saved a lot of wire bridges. Maybe in the future i'm going to solder some litz wire across the board.

A virgin plain PCB, ready to be mounted

(with Thorsten's circuit, that is)

I also have a Marantz CD63 special edition CD player and I am wondering what mods will deliver the best change.

Are you able to tell measured differences or are all the differences you are hearing by ear only?

Well, my mods have added 67% to sound quality, but my sound quality meter needs calibrating.

LOL @ Simon

Surley all mods to audio are for the ear only?

But yes most mods discussed on this thread have given significant gains in all areas of audio

What were those mods if I may ask?

Well, my point is..I have seen fist fights develop over the sound of capacitors and if you blindfolded the same people they couldn't tell what the better sounding cap was.

I don't put a lot of blind faith into what people think they hear in the way of changes. Has anyone run any distortion tests to see if there was an improvement?
