I do the exact same thing, I use an old Marantz amplifier into a big floor standing hifi speaker. The Marantz has bass, mid and treble controls, plus low and high filters, which allows me to select any sort of audio bandpass I want. I can select various receivers and have one speaker in the shack, plus the tape out if I want to record something.
My K2 audio sounds fine on cw. Not a huge amount of background hiss from the chips and there seems to be plenty for me. I don't have the ssb board, so cant say how it sounds on ssb, but that is somewhat pointless to me anyway. Funny, but there are good sounding modern swl receivers, with nice speakers, adequate audio power, bass and treble controls, etc. The very expensive ham gear has general coverage, but what for? Maybe the manufacturers limit the fidelity to reduce the noise, but that should/could be an adjustable option...
