Edward ★★★★★ Oct 13, 2026

I swapped in this amp to drive a pair of floorstanders and the highs are noticeably sweeter without any harshness. Considering it's the most affordable stereo power amp in the lineup, I wasn't expecting this much control.

Kevin A. ★★★★★ Sep 15, 2026

The bass coming out of my bookshelf speakers now has actual weight to it, and the highs stay smooth instead of getting harsh when I turn it up. For the price of their most affordable stereo power amp, I wasn't expecting this much control.

Wasn't expecting this much warmth in the highs for the price. Paired it with my bookshelf speakers and vocals sound sweet without getting harsh, while the low end still hits deep when I push it. Easily the best money I've spent on my setup.
