Are DACs superior to top-graded regular CD Players

DEvil is in the details. Get a good one either way, use good quality wires if needed (need not cost much) and you should be golden either way.

In normal cases, the DAC used in either case will largely determine how things sound. So you have more flexibility to "tweak" the sound with an external DAC. You have more convenience and still very good results if a CD player if you choose the right one for you.

When techs talks about caps getting old/tired and drying out this is directed at Electrolytic Caps.

What you replaced was a coupling cap if you used a Mundorf not an electrolytic.
From memory this JVC is direct coupled with dc servo's, ergo no coupling caps.

Now lets get back on the OP's subject and stop hijacking his thread.

Either that or they're talking about Schubert.

Nice attitude George..

Yeah, shoot straight and there no room for error, I don't know how to sugar coat things.
There's just too much voodoo in this obsession, like the sound of different mains fuses and such.
