Product details
Fezz Omega Lupi is a stereo valve headphone amplifier using a push-pull Class AB1 output circuit. Four PCL86 valves perform the output, preamplifier and driver functions, with a maximum rated output of three watts per channel.
Impedance matching for headphones
The front impedance selector provides settings for headphones within the specified 32–600-ohm range. A conventional 6.3 mm headphone socket connects wired headphones, with listening level adjusted by the front volume control. Automatic bias adjustment manages the valve operating point. Fezz specifies a 20 Hz–120 kHz response within three decibels and distortion below 0.3 percent.
Analogue source connection
An RCA stereo input connects a suitable DAC, player or other line-level source, with an RCA signal output provided on the rear. A turntable requires an appropriate phono stage before connection. The Evolution chassis is offered in seven enclosure finishes. A protective valve cage and remote are optional equipment rather than assumed additions to every package.
