Going from a 30 watt amp to a 300 watt amp gives a 10 db increase in headroom - if your speakers can handle the extra power! 10 db is perceived as "twice as loud"!
Why would 2 schiit aegir amps sound the same as 1?
My setup is forte 3s, schiit freya+ preamp and 2 schiit aegir amps. They accidentally only sent 1 amp last week so I was able to trial my system for a week before my second amp came and I switched the aegir from stereo mode to two monoblocks. Yes my speakers are high sensitivity but I’m surprised I need to turn my volume dial to roughly the same spot on the dial. I was definitely expecting more going from a 20 watt stereo amp to two 80 watt amps. Overall I’m happy with the sound but maybe I just don’t need both amps?
