With every design stage focused on one thing, sound quality, the Bellari PA253 Stereo Power Amplifier makes listening to your music collection rewarding. The PA253 connects to speakers with impedances ranging from 4 to 8 Ohms to deliver 42W RMS at 8 Ohms and 50W RMS at 4 Ohms (both per channel).

There are stereo RCA connectors in the back for connection to your preamp, DAC, phono pre, or other players. For quick accessibility, there is a 3.5mm TRS input jack on the front panel with the same functions as the RCAs on the rear.

Connection to the speakers is via two pairs of binding posts on the back panel. A large volume knob controls the output level for both L/R channels.

Made in Salt Lake City, UT
  • The chassis is made in Salt Lake City, Utah. The steel sheets are cut, bent, formed, and finished, then powder coated to a high-gloss red, all done by US labor. Bellari tests the PCBs and sends them to mechanical assembly, where the PA253 is then completely tested again.
  • The boxes that are used are made in a facility just a few miles from Bellari. Even outbound shipping boxes, biodegradable peanuts, and printing materials are made in the US.
  • Some parts, such as the power adapter, jacks, knob, and ICs, are not made by Bellari and come from countries other than the US. The company prides itself on keeping as much as it can in the US, including 100% of the product development and design.

  1. Marty –

    My Bellari power amp is just right for computer sound. It runs cool, sounds great and doesn’t take up much room on the desktop. Combined with my Fournier preamp and Orb speakers, it’s an all U.S. made system!

    Just needed a small amplifier at the bedside for my Wi-Fi radio run it low volumes a lot more power than I needed. Sounds awesome with the Bellari eq! Doesn’t even get warm, build quality great!
