« Nice, class A sound »

I've been using it for two years. Having tried out lots of amps, it comes out pretty good: it's Class A! It makes the room warm up. Wooden sides, black paint with a metallic protection filter on the inside and connected to ground: They don't make them like this anymore...It's excellent for the price. Impressive sustain, very stable stereo image, it takes several minutes to warm up. Very good bass foundation. I always use several systems to judge a sound (amps, speakers) and this amp is really worth it because it's a pleasure to listen to it, it's never aggressive. If you want more pep, you'll need to look for another amp. But eagerness should always remain under control, or it can turn into aggressiveness. Fortunately, the SU7700 knows how to stay in control: Bravo!
