I have a pair of 3.6's also and spent 6 months looking for the right amp. Bryston is a great way to go and probably the best price performance you will get. I have only heard the 7b's and they are great. The only step up you can make from here is a high power tube amp. The difference is staggering, but so is the price tag. Some tube amps to try are VTL and Audio Research. I am currently running VTL's with my Maggies.
