Absolutely they will sound different largely due to output impedance difference as per @asctim and the difference in distortion. The only way to know which you prefer is to listen and compare.
Benchmark AHB2 compared to Rogue Atlas Magnum III
Very different amps. Paired with Revels F208, and a Benchmark DAC3, do you thing there will be a difference in the sound? I am unsure if the F208's can reveal the differences. If there were to be a difference with these speakers or an upgraded speaker, what might the differences sound like, or maybe not much difference between two great amps? Thanks. I have never owned a tube amp. I have listened to this Rogue amp on different speakers though.
