Just wondering since I just got my Sherbourn up and running. It's a 7/2100 - so 7 channels and so far, since I'm still trying to find a deal on 80s or 100s, I can only make use of 3 of those channels. My question is: Is the amp still consuming 7 channels worth of energy in its capacitors when I'm just using 3 or even 2? Also - does it consume the same amount of energy when I'm playing at low volume levels vs higher levels? It just seems like a huge waste of potential and energy.
