Best bi-ampable monitor against rear wall $2500

I have a pair of Merlin Mmi placed a few inches from the wall and they sound remarkably good. Being non-ported helps, I think. They have dual Cardas binding posts so you can bi-amp or bi-wire if you wish but I don't think it's recommended. (Worth a call to Bobby P. at Merlin to find out.) They're also a tube-friendly 6-ohm load.

Its a pretty small room. Why not just use 1 amp. You may not have quite as much power, but you should be able to make up for it by having a much bigger selection of speakers. Another option would be to look into having someone bridge your amps for mono operation.

I used to have Merlin TSMs against the wall and they imaged terribly.
Needed to be out at least 4 feet in my room. Reluctant to use only one amp
since I just bought the second:) Not sure who can bridge the 2 amps, since
Paul Grzybek's tragic passing nobody else seems to service TADs. So I am
left with the Joseph 7RMXL, which is the only highly-rated speaker I can
find that fits the bill.

There is the Guru speakers from Europe (Sweden I think). I Got a friend that is listening to them, and like them. Those LRE's look very interesting.
