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

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.
