Here is a quote on tweaking the cd120 linear from the following review:
http://www.tnt-audio.com/sorgenti/opera_cd120_e.html
"Ian large notes that the cd120L responds well to tweaking. He suggests a good inexpensive mod is to change the input caps to 0.47uf Hi-Q black gates, and use SCR 1.0 uf caps on the output stage. I would endorse both these proposals as likely to lead to worthwile improvements, having tried both series of caps myself, but this review is straight-from-the-box."
I would love to do this because I can solder but I don't know where these caps are located.
