Help adding Vcaps to Jolida JD100 CD player


Hi,

I've soldered and done basic stuff like that, and have a basic understanding of electronics. What I would like to do is to add V-caps to a Jolida JD100 CD player. What would I need to buy, and what would I need to remove/add to do this modification? If someone could post instructions, it would help me, and probably others with this excellent CD player! Thanks.

Dear Steve: +++++ " . My feeling is that why go to the trouble of semi-permanently altering the sonic character of an optimized component .." +++++

That optimized component is optimized at a price range. Jolida can't use V-caps because of the high price of these caps, if they decide to use V-caps they have to do an increment on their retail price, same for tubes or other build parts.

Now, for many years I always was looking for to " take out " the best performance of any audio item I owned. Any time that I swap caps I had a different " sonic character ", like you say, the issue here is to really know when that change is really a better music/sound reproduction performance.

Regards and enjoy the music.

I'm with Raul, here. That player may be 'optimized', but it's definitely to a price point. I don't know what this Jolida CDP retails for, but including LOTS-better caps could easily increase its retail price by several-hundred dollars.

Capacitors in both coupling and powersupply positions definitely have a sonic character, and all that character is distortion. I've read for decades that caps, of all the 'passive' components--caps, resistors, diodes, inductors--we use, are the most characterful, and that's no compliment.

But this should't be done indiscriminately. Thwang, getting a schematic diagram is the FIRST and very-important step to this process. You'll also be able to identify the resistors in series with the signal that could be replaced and also the decoupling caps that could be upgraded, the first 3 things I consider for replacing. GET THAT schematic! :-)

Of course, you could just trace the analog circuitry and identify the couplers and their load resistors.

BTW, choose caps carefully--this process can be VERY expensive.

Replace only the signal path "coupling" capacitors with V-Caps, and I would recommend using oil-caps bypassed with Teflon caps. There are other caps that are better for power delivery and "decoupling", such as Black Gates

Dear Tony: I agree with Steve. Btw, the teflon bypass caps can be from V-caps, too.

Dear Tony: Jeffrey ask you for the schematic diagram. This is all about and I think that Jeffrey can give you the support for to know what caps do you have to change.
