yeah, i actually enjoy the chainsaw quality the 5150/6505 has to it. other amps are just too...smooth. i don't like smooth. it's all preference like you said
I bought mine 3 months ago, never looked back
most brutal amp i've ever played, that's for sure. I've played rectifiers, mark V's, marshalls, and a 5150III and none of them held a candle to this beast.
happy NAD, OP
