This amp and its big brother were reviewed by a very experienced audiophile as coming very, very close to a world famous $20,000 amp. Yes, the sound that good.
The Qualiton A20i is a Stereo, Class-A integrated amplifier featuring push-pull circuitry. The rated power output of the appliance is 20 W at the most, each side. The outputs at the rear panel can be connected to 8 Ω nominal impedance speakers. The design of the output transformers of the power amp enable to connect the amp with 4 Ω nominal impedance speakers as well. This entails a slight deviation from the parameters indicated in the technical data sheet.
At the front panel, the volume control potentiometer and the input selector rotary switch are connected to the same shaft. Indicators informing about the actual state of the amp are located at the front panel too. It can be monitored whether the appliance is ready for operation (if so, the LED next to the volume control turns from red to white light). The user is also informed about the actual position of the input selector unit. The amp is made of solid, 1.5 mm thick, polished stainless steel sheet.
Warranty: 2 Years. Tubes 6 Months.
