After switching to the MC611,s my KEF Blades really opened up at low volumes, seriously! I went to the shop to buy a small pair of 2 way, persona b speakers to use for low volume late night listening because the big full range speakers sucked at low volume. At 70 db the blades had no snap, no dynamics or anything that brought attention to the music. I decided to try new amps instead. Out went the Hegel H590 and in came the MC611's and I was instantly startled! #ven cold fresh out of the box the amps, at less than half a watt were giving up layers of bass detail and layers of soundstage depth, detail and tone I never got at low volume before. Does the autoformer act like a loudness button? is this feature the reason tube amps sound so good compared to SS? I have to say I couldn't have imagined this much improvement from a power amp working at idle, 1/100th of its rated output.
Can anyone explain what's happening?
 
Sounds like the McIntosh better matches your preamp in terms of sensitivity. Nothing against Hegel but I am a McIntosh fan, and their autoformers do make a difference in sound. Regardless, enjoy the improvement in synergy in your system.
