A-2000 25th Anniversary




The Allnic Audio A-2000 25th Anniversary is a 100 watt (pentode) push-pull, stereo power amplifier. Like its integrated amplifier brother, the T-2000, the A-2000 25th Anniversary is pentode/triode switchable “on-the-fly”, providing more than 50 watts in SET sounding triode mode. The A-2000 25th Anniversary offers stable, resolute power in the proverbial velvet glove, along with amazing, revelatory clarity, incredible dynamics and drive, articulate and powerful bass, and standard setting low noise and distortion.

New Review and award – July 2021!

Part-Time Audiophile names the A-2000 a Reviewer’s Choice!

It’s rare for me to review a product like this which is just so thoroughly sorted, and at what I find to be a very fair price…

 If you’re in the market for an amp that does what the modern 100W per channel solid-state stereo amplifier purported to do; power anything big or small, do so quietly and with great character and flat frequency response, I’m here to tell you that you can do one better, and even get those magical glowing vacuum-sealed bottles while you’re at it. If you have an opportunity to lay ears on this amp—don’t miss it.
