First of all, thank you for building these wonderful little amps. I have had a few days to listen to them so I thought I would give you some early impressions.

Right off the bat, the clarity and speed is very impressive. I have speakers that are a relatively easy load, so the amps have plenty of power. In fact, I am amazed at how much grunt they have! I took your advice and played them initially without a preamp. I have both a digital source and a turntable, and they sounded fantastic without the preamp. I put the preamp back in the chain, and got through two songs before I took it out again. I’m ready to sell it! I don’t mind swapping sources, it sounds that good! I should probably look into passive preamp or some kind of switch box.
