I have the Whispers and prefer bi-amp to single amping. That lets you get the Steradian (Step One) of the the signal path for the highs with that speaker. Even without that consideration, bi-amping the Whispers sounds better. I use four Bryston 7Bs. I also think the Legacy amps sound great with Legacy speakers, at least as good, if not better than my Brystons. The Ultra Monoblocs sound very good indeed, especially for the price.
which amp for legacy focus
i have owned these focus for three years and love them. I am driving them behind a legacy power amp. I am getting to the point where i want to take these speakers to the next level. I am considering a new amp or two. Biamping interests me. I have auditioned a krell ???(250 watts),mcintosh 352,(350 watts)and the bryston 14sbt(500 watts) as singles and a couple of bryston 4sbt's(250 watts each) as duals. As no local dealer has the focus speakers I can not audition on the speakers until purchase. The biamping in theory makes sense I am just not sure if the extra $$$ is worth it. There is approx a $1500 difference bewtween the single amps and the biamps. Any comments and opinions?
