I'm looking for a small practice amp that I can keep near my desk - don't need much volume but would like something at least somewhat hi-fi. If I can find something that sounds good for recorded music I could get one small box to replace the practice amp, mixer and computer speaker combo (and associated tangle of wires) that I'm using now. I know a lot of small practice amps have stereo inputs. IME most sound like crap when playing an mp3 through them due to the heavy midrange voicing and lack of highs. Are there any small practice amps under $300 that fit the bill?
