Your favorite KT 150 based amplifier?


Help me decide for powering my Graham Audio LS5/5s.  Have an EAR 868 pre.  Considering CJ, ARC, Octave… but lots of others out there. What’s your favorite that you’ve heard?

After decades of wanting a Audio Research amp, but still reticent because of tube life and their reputation for unreliability I went to a demo of the new REF ARC 160m. They finally put the tubes under microprocessor control… auto biasing, extending tube life and reliability. I said as soon as they released a stereo version version I would buy one. I did. It is an incredible amp and has significantly improved my system. The amp also has been reviewed everywhere gaining the highest praise. A tremendous amp, without the fuss of some. 

The ARC REF75se is a long lover amp as well.


Looking back, I probably should have bought a ARC amp years ago. But really glad I did now.
Well I've only heard one. The Allnic T-2000 and it is an excellent sounding amplifier.

I just recently purchased an Octave V70 Class A that is stunning. It came with KT120’s and I have went back and forth with KT150’s. Love them both so I can’t really decide. With my Spatial M3 Sapphire I think I prefer the KT150’s but either way it is a very nice pairing.
BTW: specs are

Nominal impedance 8Ω
Sensitivity 88dB SPL (2.83V, 1m)
Recommended amplifier power 50 to 250 watts unclipped programme
