The Best Amp for the Price of Dirt

Hi Fi world magazine reviewed these amps recently.They concluded they are excellent value PA type amps but did not measure or sound up to dedicated Hi Fi standards.

If you want cheap amps that do sound fantastic you probably can't beat the Sonic Impacts or kit chip amps.

The Hi Fi World magazine review showed that these amps do have unusually high distortion.Which is probably the main reason they said they were not really suited to serious hi fi use.
This may or may not cause speaker damage but it is probably a good thing to use them carefully and why they could not recommend them despite their apparent excellent value.
They should be safe for driving woofers though.

Creml,
The A500 was reviewed in Hi Fi World December 2006.

To quote-
"Unlike hi fi amps the A500 suffers considerable crossover distortion even in the midband...whilst it measured 0.14% at 1 watt1kHz this figure rose to an unacceptable level of 1% at 1 watt 10kHz....this is classic crossover distortion in large quantities and it will be clearly audible as a roughening of the treble."

Their Verdict-
"Versatile and very powerful amplifier for next to no money,but needs careful matching to assuage distortion.

I am no Behringer knocker.I own a DCX 2496 myself.

For the little the amps cost,and their power output,expecting them to be near perfect is probably expecting just too much.Doesn't mean in the right system they can't produce pleasant sounds though.
