In Barn for Review: Enleum AMP-23R Integrated Amplifier

My hi-fi underground has been buzzing, again, this time about the Enleum AMP-23R Reference Compact (Integrated) Amplifier.

The diminutive Enleum (9″ square and 3 1/4″ high with the Enleum footers) is a Class AB integrated amp that uses no negative feedback and produces 25 Watts per channel into 8 Ohms (45W into 4). There are two pair of single-ended RCA inputs and a pair of proprietary ENLINK current-mode BNC inputs for tying the AMP-23R to future Enleum source components (like a DAC).

I’ll point you to the Enleum website for the scoop on the finer points of what you’re looking at, which I’ll talk about more in the review proper, where appropriate.

The AMP-23R weighs less than 9 lbs. (yay!) and also includes a headphone amp (part of the buzz that’s been buzzing in my ear).

I’m a fan of simple integrated amps but as they, the proof of the buzz lies in the listening. Stay tuned!
