Rogue makes good stuff. I've owned their gear and I vist their factory every now and then so I can vouch for the sound AND the produciton quality. The abliltiy to switch between ultra linear and triode output is a great standard feature of their amps
Their designs are conservative, focusing on value & watts per dollar rather than uniqueness. They do sound great with many speakers (I like them with Vandies and Maggies best) and they are tighter in the bass than many other tube amps. The one complaint I have is the amplifier circuits they use are very high gain (30+ dB... the combined gain of a set of Rogue separates can exceed 50dB for line level, which is way too much). This can mean no volume control capability for many users. Aside from that they are among the best audio values out there IMO.
BTW 100 watts from a pair of KT88s (fixed bias/ultra linear connected) is well within spec, so 120 from 4 is not hard driving.
