Feliks Audio Arioso 300B Integrated Amplifier

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

A rich, muscular sound that rings and sings and swings without ever crossing the line into excess. Ccpable of driving the right speaker with real authority, richness, and subtlety to heights whose only limit is the music at play and our ability to pay it the attention it deserves. Bravo!


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.
