Great sound for the price

Like the Sonic Impact before it, this is a great sounding amp with heaps of uses. It has a great musical presentation that embarrasses many other amps at 10x the price. Don't be fooled by the size as it copes well within it's limitations but don't expect it to be a powerhouse in larger room. The only issue I have is the spring clip speaker terminals (just tin the ends of the speaker wires to be safe from loose strands).
