Do not know what your budget is...but if you are considering the Stratos you might consider the Emotiva XPA 1 mono blocks...
I am not saying they are better...but the work well with Mag 1.7's across the entire sound spectrum---especially on organ music...I do not know if they are comparable to Bryston or the John Curl designs Halos and j 1 mono blocks....But on well recorded music like Blue Note and the Mercury Presence series they are brilliant. They are also very cheap under $2000 Also Macormack gets good reviews.
