I'm using a TD124 a Decware ZP3 and MC240 cables to QSO 808 monitors. So simple. The gain is on the MC240. I was listening to a bunch of Al Greens old LPs yesterday. :-)
I added a C20, either or was heaven, the difference was not just tone control but, a variable loudness, bass contour with bass and treble control. Did it make a difference? BIGGER :-) What a difference a preamp can make.
I can set everything flat and it's as neutral as can be and a pitch black background. Samra C20, dead quiet. Little LP noise between songs..
Regards
