Which solid state amp loves a 4 ohm load?

Bryston 4B-ST at around $1300 or Hafler 9505 at around $800. Both amps are 250 watts/channel into 8 ohms and about 400 into 4 ohms. Both have balanced and RCA inputs. I own one of each and have been driving my 4 ohm speakers for a long time, so I can vouch for them.

It takes a monumental experience in audio for me to be impressed with an amplifier. I use 4ohm speakers that dip to a solid 2ohm in the bass. The BRYSTON 4bsst is just amazing. Neutral to your source component but wait a minute.... I have re-read your post. 60x20 room. Not a problem get the 7bsst mono amps and don't look back. Seriously, I never thought of ever owning/listening too etc. a Brytson amp. Mty dealer lent me a 4bsst as a stand by amp- but after a month I want to buy one. Been doing this for a LONG time. These SST amps are extremely musical.

Brace yourself or skip over reading my post if you are only looking for "nice words". I would rather "tell it like it is" and let you sort things out for yourself. At least with this approach, you know what you're dealing with and what to expect.

First of all, you're going to have problems with your speakers in terms of trying to place them and achieve relatively flat response in the bass / mid-bass region. The overall design, in specific, the placement of their woofer, is far from optimal. You can't mount a single woofer up that high and have it work properly.

Secondly, you should do some research of your own on the subject pertaining to what amps do well into lower impedances. Some of the amps mentioned here really don't do well into lower impedances. This has been covered in these forums and a magazine review also.

Thirdly, when looking at power ratings of an amp, look at what the amp clips at into various impedances, not what it is rated at. This will give you a better idea of how sturdy the entire amp ( both the power supply and the output stage ) really is.

Fourth and lastly, that is a BIG room. If you expect to generate high spl's there, your speakers will be eating power from an amp like a stranded survivor on an island would eat a bag of M&M's that drifted ashore. Take that into consideration. Not only will the sound be cleaner, but you'll have less chance of driving the amp into clipping and / or damaging the speakers from the associated distortion. Sean

InnerSound ESL. 600wpc into 4 ohms. Kicks Maggie ass. You might be able to find one in your price range used.

Classe CA200 used - drive Thiels, average 2.4 ohms aplenty in my large room.
