Audio Mods for the Jolida JD-100A CD Player

Bill at Response Audio mods Jolida http://www.bellaextreme.com/jolidacustom100.htm

An alternative to consider is this: I have the Jolida with only minor mods from Underwood. As opposed to mods of the unit I added a stand-alone DAC from PS Audio. I weighed the pros and cons of a $500-$700 mod vs a $900 DAC that would work with all sources. This includes a computer through the USB, Toslink digital in (DVD) and coax digital in (CD). There are many capable DACs out there. I find the Jolida to have a reliable transport and the jitter is quite acceptable for me and the PS Audio DAC III reduces the jitter to very low levels. It has turned out to be quite a nice combination. You also have to consider a quality coax and Toslink fiber-optic cables. The ones from Blue Jeans cable are quite good and meet all specifications. Good starter cables. Anyway, good luck. Sound advice is plentiful, let your ears be the best judge. Good luck!

I own a level 2 mod JD 100A by Underwood Wally and parts Connexion,  that I use for all my CD's.  IMO opinion it is an equivalent sound on CD from my McIntosh MCD 301.  Obviously it doesn't play SACD.  I am considering selling but I see a stock one listed at well under the level 1 mod px of $690 so.........there's that but I don't think you can appreciate the sound of this hotrod without standing in front of it  

I see what others say about changing the designer intent but less so here on a TUBE based CD unit.  A different sonic flavour maybe but floating amoung the invisible blacks are blacker resolving more low level detail, spatial and ambient retrieval;  smoother yet more detailed and dynamically more exciting; tonal balance; tonal balance is more even.from bass to treble while fleshing out the amazingly liquid midrange of the stock machine;   Imaging is cleaner & more defined while bass is dramatically improved. The modded unit has much fuller weight and authority. The modded unit transcends"one note" flabby bass. It sounds more like solid-state in this area.  If you have a chance to hear a modded one take. I dont htin kther's a better sounding CD machine under $5k and maybe more.
