Alper,

While I have heard ill effects with speakers side by side, it's not saying it wouldn't work.

Years ago, a customer was coming to my place to pick up his HR-1's and I placed the 2 speakers side by side, and with a remote switch I was able to toggle back and forth the two pairs.

For some reason, the outside pair (my original pair) sounded great while the inner pair was anemic sounding at best.  So much so, I tore the new speakers apart thinking I had missed something in the crossover. Only to find nothing wrong. Granted, your first thought would have been break-in, as my pair had many hours on them. Not the case here!

After reassembling them, for some odd reason I switched location of the two sets and the outer pair, which was the new pair, was the better sounding set.  

On the other hand, a few years before that, at Steve's old place we decided to neaten up the location for all the speakers by building a platform off to one side to keep th speakers not being played. We used to just have them all up on one larger platform and pull forward the speakers we wanted to listen to. When we finally sat down for a listen, it didn't take either of us too long to notice a huge change in the way things sounded. In this case, the single speaker sounded worse. So we went back to keeping most of the speakers on the large platform and thinning the herd, by placing just a few on the side platform.

Hope this helps,
Zygi

Dear Zygi and Mark,

Thanks for the insight.  I will have to try and see, yet it already looks weird in my room.  As this is not a dedicated listening room, having two sets of speakers side by side is not aesthetically appealing (at least, to me).  The thing is I cannot get rid of either of the amps.  I am willing to get rid of the B&W's, but then my ProAc's are not very efficient and the SE84UFO would struggle driving them even though I loved the sound of the combination at the expense of volume.  

Anyway, thanks again...

Best,

Alper
