New proud owner of a Halo A31 3 channel amp running my fronts and center. Just got it up and running last night, looking for advice on the gain control settings on Halo amps. The manual says normal setting at 12 o'clock is THX reference standard which means a 1v input from the pre-amp converts to 28V. My Marantz AV7005 using balanced outputs is specd at 2.4V. Should I turn the gain down below normal on the Halo? I do notice a slight hiss from the tweeter that wasn't there before with my Rotel amp. Speakers are GoldenEar Triton 5s rated at 90 db efficiency. If I do turn the gain down a bit the hiss almost totally disappears, am I just sacrificing sheer volume output by doing that?
