Here's another note of appreciation for the 4B3. I find it musical, neutral, non-irritating (like music), and unflappable. I tried a couple of esteemed & more expensive amps and prefer the uncolored quality of the 4B3. Very happy to have it in my system ... for a long time, I'm sure.
Oh, and it does all that without dumping hundreds of watts of heat into the room like some of the competition.
Well done! It deserves all those awards!
