BALANCED AUDIO REX 500
BAT's New 2023 Reference Power Amplifier
"The fully balanced purist-approach-based REX 500 power amplifier is the ultimate expression of BAT amplifier engineering. It couples quickness, slam, and dynamic range with an extended, deep soundstage and an exquisite fidelity to the timbre and texture of instruments and voices... It’s time you experienced such beguiling sonics for yourself"
MADE IN THE USA
BAT REX 500
Massive Power Output, Simplified
Balanced Audio Technology’s flagship solid-state power amplifier, REX 500, represents the culmination of the company’s decades-long pursuit of sonic and engineering excellence. Victor Khomenko, BAT’s chief designer, observes that the unit’s massive power output is largely academic. “BAT has never designed for power alone, and I am most proud of the elegant simplicity in how the REX 500 delivers that power,” he says. For those who demand numbers, the stereo REX 500 produces 500 watts/channel into eight ohms and 1000 watts/channel into four ohms. In mono configuration, let’s just say that the power is more than adequate.
The Benefits pf a Purist Approach
A true dual-mono design with independent channel assemblies, power transformers, and separate power cables for the left and right channels, REX 500 adheres to a purist approach that offers benefits in the forms of soundstaging, depth, dynamics, and insight. The gain stages of REX 500 feature the highest current delivery ever achieved in a Balanced Audio Technology design. REX 500 also employs a new power supply topology (Push SuperPak) and the largest SuperPak (as measured by energy storage) of any product in BAT history.
Fuseless Protection Circuitry
REX 500 incorporates a new protection circuit that eliminates the need to replace internal fuses. Many of us have dropped a needle on a record with the volume set too high or inadvertently shorted speaker leads when changing speaker cables. If you make a mistake, you can reset REX 500 by pressing a rear-panel button. That’s it. The elimination of internal fuses also permits REX 500 to handle higher currents without impeding the circuit's operation. Indeed, the best-sounding fuse is no fuse at all.
