I sold off my A6000. The buyer's friend was so impressed he desired a pair. I found out the A6000 was discontinued last year. There does exist one silver chassis available if someone had the desire.

But the good news from the gentleman who is a long time A6000 owner and the person I modeled my system off. "On the triode setting, the M-3000s sound a lot like the A-6000s. Nice to have the flexibility anyway. And KT-150s are way cheaper than EML 300B XLS!"

It seems the M3000 MKii is the sweet spot for sound, price and care free maintenance. Those amps will drive anything and I am please they produce a similar sound to the A6000's which I adore.

Cheers!
