Avery ★★★★★ Oct 22, 2026

Finally got a proper SET amp for my Sennheisers and the clarity on complex classical passages is stunning, the handcrafted build feels solid as a rock.

George ★★★★★ Oct 20, 2026

The point-to-point wiring is a thing of beauty once you pop the hood, and the OTL design keeps my high-impedance cans sounding airy and open instead of muddy. It’s been on for six hours straight and the Class-A heat is a small price for that rich, liquid midrange I keep chasing.

Tube amps can run hot, but this one sounds so alive I forget about the warmth. The point-to-point wiring gives a clarity to vocals that makes my headphones feel brand new.
