Focal 1037be's Amp Suggestions ???

Your amp should be fine. What are you looking for or missing (bass?). I have found this speaker to be a little picky (in the bass) about placement. How far are they from the rear/side walls?

I have heard these several different times, two different rooms. Once was with 90 watts a channel Arcam mono blocks. It was plenty of power, the room was 15X22X9 and I sat about 10 feet back. They were close the rear wall in this room (about two feet). They had plenty of bass but it was a little muddier than the other room.

In the other room (about 14X20X8 I sat 8 feet back) I heard them on Arcam mono blocks and some way out of my price range Krell amp. The 1037s were pulled way out into the room (5+feet). Because of this they had NO bass. The Krell was more refined than the Arcam but I did not feel that it came from more power.

My guess is that it's not the amp, but the large room -- you have a lot of cubic feet and most speakers can't really fill such a space.

James63, They were sitting about a foot from the rear wall. There isn't any sidewall. I moved them further apart and out a bit more. Well, maxed as much as my cables will allow. Actually, it sounds better. Maybe I should get longer cables. I still have three or four feet more that I can utilize. They were about six feet apart and now they're about nine. I also towed them in a bit more. Raquel, your point sounds like the problem. Maybe I should move everything downstairs to the den which is 15'x15' with 8' ceilings.

I agree..IMO the room is too laarge for the Focals

You definitely do not want to move them into a square room (15' x 15'), which would be the worst possible acoustic environment - square rooms accentuate room modes, usually guaranteeing large peaks and dips in a system's frequency response.

I assume that you are reluctant to part with such nice speakers, but the space you have calls for something bigger, assuming you listen to challenging music (orchestral, loud rock). Yes, adding subwoofers would help, but your main speakers are, at the end of the day, best for mid-sized rooms (one midrange driver per speaker).

The sound is somewhat different than the Focal house sound (but reasonably neutral), and their look will not appeal to a lot of people, but a used pair of Dynaudio C-4's would be an affordable option -- they are very good speakers that will fill large rooms and should work with your amp (I am not otherwise going to get into recommending speakers, as there are so many variables and available options).
