There is no problem with doing what you ask. The sonics should improve so long as the quality of cabling used remains consistent and the way that you split the signal from preamp to amp is done in reasonable fashion. The only potential problem that could happen is that your preamp may not like the lower impedance that it sees running into the extra channels, but that "probably" won't be much of a problem with SS gear.
If you do this, i would exercise caution at first. The sound may end up being cleaner than what you are used to. Since distortion adds apparent volume, the lack of distortion will tend to have you playing it louder than you think it is. Your tweeters may not like this too much and go up in smoke. B&W's are one of the few speakers that i know of that seem to have problems with blowing out tweeters in a non-clipping related situation.
As a side note, once you hear your speakers like this, it may be hard to go back to one channel of amplification per speaker when you do fill the rest of the system out :( Sean
