Techie question!
You can buy phono pre-amps with valves these days which make your vinyls sound "warm" again on modern digital amplifiers.
I wonder if you could use one inbetween your CD player and amp to add some warmth back into the music, or would it (even at the lowest setting), blow your amp?
If you keep your setting on the (very) conservative side your speakers (blowing an amp is a bit harder) will stay intact. It won't be very effective however, since pre-amps are meant to make sure there is any sound at all from passive electronics like turntables or microphones first, with the added warmth as an often welcome side effect. The modern phono pre-amps just make sure that your record sounds the way it was meant to in the first place.
A great deal of the percieved warmth in vinyl was achieved by saturation (a form of distortion, basically clipping the output to a signal well over 0 dB), while any signal over 0 dB in a digital recording will lead to digital distortion which sounds horrible. I recommend fiddling with your amp's EQ-settings over inserting an extra amp.
If you really want an extra pre-amp, try ripping your CD, mastering it with an VST or hardware pre-amp and then re-recording it on a blank CD. Hardly worth the hassle imho, but there ya go.
