Mystere pa11 (show piece/demo) – This amplifier is incredible. Mystere is part of the same company as PrimaLuna, Durob Audio BV in The Netherlands. Because of that it adheres to the same guiding principles: The finest build quality that put megabuck brands to shame, point-to-point wiring, Adaptive AutoBias, and more than you should get at its price. It’s 40 watts per channel using EL34’s. It can also use 6L6GC tubes and other tubes that have a smaller diameter base. So who should buy this amp? It’s a pentode design, and for that reason the mid-band has a resonant quality like you would get from a single-ended 300B or 845 amp. But unlike those amps, it’s push-pull so you get real bass and power so you don’t have to use high-efficiency speakers.

Comes with original box, manual, two-year factory warranty, and tubes test as new. It’s a $1995 amp and comes with Uncle Kevvy’s seal of approval. Steal it at $1395

Mystere pa11 Stereo Power Amplifier

When we break down our integrated amplifiers into separates, we offer much more than the pre- or power stage of that integrated. So while the pa11 power amp evolves from the critically-acclaimed ia11, it offers much more. For instance...

We once again offer 40 watts of pure pentode output per channel, maintaining all the glory and beauty of tubes. However, the transformers in the pa11 are completely different, providing much more efficient power that delivers incredible depth and punch. We do implement a very modest amount of global negative feedback to make the amp rock solid.

We also use a high power, low impedance, solid state rectification circuit followed by a massive pi network using the highest quality caps and resistors. In the signal path are only two high quality Solen coupling capacitors.

Finally, we implement Mystère’s proprietary Adaptive AutoBias circuit, specifically tuned for Pentode operation. Optimized for EL34s, the AutoBias circuit is continuously tweaking each tube to its sweet spot. No biasing, no need for matched tubes, no worries.
