both are great companies . I worked part time at a dealer that sold both and are very familiar with both. I bought and still use Rogue m150s with revel f32s and it sounds great. I have four of my audio buddies that bought Rogue amps after hearing mine. I love them. I think they offer fantastic value for the money, and they keep upping the build quality with each new generation. check out the pictures of Rogues new five grand pre-amp , outstanding build, all aluminum case, mundorf supreme caps ect. The one feature that the Rogues have is being able to bias each output tube individually, and having lived with this I dont know if I could do without. Tubes do drift, even if it is a small amount, It is a real ear opener just how much sonic difference this makes, It sounds WAY better when they are all biased to the same number MA . Everything snaps into focus, clearer from to to bottom, and the sound stage is much better also. And you can play with the bias number, 45ma sounds different from 40ma or even 35ma, all which you can use to tailor the sound to your liking . The rogues are also very good for tube rolling , if your into that sort of thing. Do they sound as good as a pair of Ref 210 monos ? No they dont, but they are not 20,000 a pair either. So its not apples to apples. But they come closer than you might think, for 15,000 less. good luck, Chris
