It's been really really tough deciding what to keep. I have 8 systems up and running and I really only listen to 3 of them so I figured it was time to pare down. At the end of the day, I like 300b tubes and the way they sound. I also really like these amps and the baby black beauty's. I think the Carver amps deliver better bass and the 300b's have a magical sweet spot in the mids....It's not even an apples to apples comparison, it's more like apples and oranges.
The AN amps I run sound great on the horn systems but sound like crap on Khorns. The Carver amps sound great on the Klipsch's and really good on the horns, I think they probably are more versatile and will match with a wider range of speakers than the AN amps. i know what you are thinking and the answer is, you just have to hear those mids on the 300b.
