Krell KAV‑250a/3 // Vintage / Class A Solid-State Amplifier / Serviced

The KAV-250a/3 is what happens when Krell decides to build a three channel amp that’s part gym rat, part gentleman. It’s not trying to impress you with bling or gimmicks—it just does the job with relentless control and a smirk that says, “Yeah, I lift.”

Under that minimalist, brushed-metal faceplate is 250 watts per channel into 8 ohms. It doubles to 500 into 4 ohms, and can push a full 1,000 watts when bridged. That’s serious juice—and it delivers it with Krell's signature low-distortion finesse.

Heat sinks line the flanks like armor. This isn’t a “hide in the cabinet” amp—it wants breathing room and a little respect.
