Shanling CD-T80
Copyright 2011 Troels Gravesen

Vinyl is my main source of music, but I do have a lot of CDs and care about what comes through. I bought this player from Cattylink/Hong Kong and it's been a good workhorse for several years.
Some info can be found on diyAudio on tweaking the CT80 and the only thing I have done is changing the output caps to silver/golds from Jantzen Audio. I haven't tried changing the integrated circuits like suggested from the link. I tried this with quite a few CD players over the years and never really found much improvement.
Visitors have kindly brought in serious expensive CD players, but none has convinced me that a new player was needed; this even goes for a cutting edge 24 bit DAC.
Apparently most tweakers go for the op-amps or the buffer tubes, but no one seems interested in the output capacitors, a bunch of electrolytic caps! This would be my usual suspect and and do believe my current silver/golds outperforms the electrolytic caps.
I also bought NOS WE396 tubes, but these are no better than the 6N1P tubes so don't waste your money. I bought a box of 6N1P from Russia for nothing.



The Jantzen Audio silver/gold caps. Here some prototypes, the current Jantzen Silver/Golds look better.
I use 2.2 uF but you may have to check your line stage input impedance if this is enough.


Unsolder the four electrolytics and connect as seen on photo.
