Increased air, space, and depth
Just plugged this in to my Decware SE34I.4 and my first impressions are coming in. There's immediately a greater sense of air and space around the music compared to the Valve Art 274b. Only gripes so far would be that it's maybe even too much air for me. If your amp lacks highs extension, this might help you but for my ears I feel this might get fatiguing and hope it will smooth out with some break in. It also sacrificed a bit of the lower mid range punch to get the highs. That said, it's smooth and grain free. Will report back with any changes post break in.
