BELLARI PA253 Stereo Power Amplifier
The Bellari PA253 is a compact yet powerful stereo power amplifier, designed and hand-built in Salt Lake City, USA. This device delivers a "Pure, clean, and powerful" sound, characterized by its clarity, detail, and dynamics, often found in equipment twice its price. Its robust steel chassis is coated with the signature "High Gloss Red" powder paint.
The amplifier powers passive speakers, providing 50 watts RMS per channel (at 4 ohms). The PA253 features simple and effective controls: a front-panel volume knob allows for adjustment of the overall sound level, while a convenient 3.5mm (male) input enables quick connection of a phone or player. On the rear, you'll find standard RCA inputs and speaker terminals.
Thanks to its short signal path and quality components, the PA253 ensures exceptionally low distortion (.015% @ 1KHz) and a high damping factor (>100), which allows for precise control over speaker movement.
