Should I max my sound card volume, and only use a little amp power, or lower the sound card volume, and use more amp???

With modern soundcards boasting SNRs of 110+ dB when operating in 24-bits you can lower the signal by about 15 dB digitally before you reach the limit of redbook CD audio and start to decrease the dynamic range of the audio.
