Category: Speaker Amplifiers

An integrated class-A SET with EH Gold 300B power tubes, fully point-to-point. Designed and manufactured 100% in Poland

The driver tubes are the CV 181-TII (“golden” PSVANE 6SN7) and the rectifier is  5C3S (NOS). The output tubes use a stabilized DC current heater supply and a special system that separates the tube heating circuit from the stabilizer system.

The entire amplifier circuit is built using the point-to-point method. It features selected high-quality components, for example the motorized blue ALPS potentiometer (for remote control), "Hi End" class transformers from Mr. Ogonowski, “red Jantzen” coupling capacitors, Caddock film resistors.

All these elements achieve a natural, incredibly detailed, and musical sound, with well-controlled bass and a rich but not overly emphasized midrange.

Benjamin W. ★★★★★

The CV 181-TII driver tubes really open up the midrange in a way I haven't heard before. Listening through a pair of efficient bookshelf speakers, the soundstage is incredibly wide and airy, even at low volumes. It's a level of detail and warmth that makes every recording feel new again.

Edward ★★★★★

The point-to-point wiring inside is a rare thing these days, and it gives the Arioso an incredibly clean, quiet background. Paired with the golden PSVANE driver tubes, the midrange has a lush, open texture that makes vocals feel almost live.

Ava ★★★★★

The EH Gold 300B tubes really deliver that lush, mid-focused warmth I’ve been chasing—it’s like the music breathes in a way my old solid-state never managed. The point-to-point wiring feels rock solid, and the Polish build quality shows in every detail. I’ve had it running for two weeks straight and
