Vinyl is my main source of music, but I
do have a lot of CDs and care about what comes through. I bought this
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.
The 6N3P output tubes most likely never needs changing.

silver/gold caps. Here some prototypes, the current Jantzen Silver/Golds look
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.
