Excellent Value!

This has got to be the most underrated line of amplifiers I've seen in a long time! The power output alone is worthy of the price, but throw in the quality components used on the board and the decent amount of adjustments to tune it in, and the price of the amp is worth it right there. The overall sound is extremely good at this price point, and it rivals many Top Name companies at twice the price! I'm very happy with this amp!!!

Well worth it!

Super happy with this amp so far. Haven't had it very long so can't comment on durability, but definitely happy with the quality. Unlike everything else these days you get MORE than what you pay for!

Amplifier

Very sleek and streamline amplifier. I wanted something subtle and this hits all the points.
