The Pre/Headphone amp sounds just beautiful and even though it’s OTL it powers anything, except maybe electrostatics, and can even work on my speakers. Anyway, it has some tube richness (not as much as the 834p adds) but is very very good with details.
The matching power amp has about 12 WPC which with my speakers is plenty. I get 90 db in my listening spot with the knob on the pre amp at just 9. The amp, I think because of the tubes it employs, EL84s, can produce and grip bass far better than expected from my prior experiences. The amp has no transformers and is very quiet for a tube amp. I think Analogue through this pair is liquid and rich - which is just what I like. And although I’m not that expert or experienced in stereo stuff, I believe this gear also delivers excellent detail and balanced harmonics.
Moreover, the sound is just real. Human. You know. But really fine. I think.
I bought these components used or demo, in fact everything in my system, except the linear power supply for the pre-amp and my turntable cartridge, was purchased second hand.
