B&K ST-202 or Forte 1A?

I would not recommend either amp. I don't think either amp could be truly comfortable with a 2 Ohm load in stock form. Perhaps the mods on the B&K have adressed this?

In stock form I think you would be asking a lot from these designs. The Forte 4A which was a latter version of the 1a might be able to pull this off (most people seem to prefer it's more open extended sound as well). The Forte is only 50 watts but your speakers are pretty efficient. It will depend on your room and desired volume. Forte also made 75 watt monos that were like the 4A. If I'm not mistaken the 4A could be had with balanced inputs but the monos (7's?) were only availibe with RCA's.

P.S. the B&K M200 monos @ 200 watts per channel should be able to do handle the load.

Just a note of caution. Some, not all "designers" will will spout a very democratic view of their products. They will tell you that most anything will work with most of their products so as not to lay a foundation that might suggest that their products are fussy and jeapordize sales. I repeat not all designers, salesman and or manufacturers ar so self serving. Many are very sincere in their recommendations. Be wary of anyone who seems to jump on your proposal and tell you that everything you have is just perfect or suggest that you change everything (and buy from them or their "friends"). IMHO, like most things (with many exceptions, Ha! )the answer is usually some where in the middle. What will work and what is a beautiful synergy can be subtly and yet significantly different.
