Behringer is probably the best value brand higher power 2 channel power amp (new). 'Budget' PA amps of good quality and extremely competitive price. Their A-500 is iirc 2*220 w, weighing only about 8 kg (18 lbs), due to its light-weight switch mode power supply, and small heat sinks.
Any thoughts on how Behringers compare for sound quality with 2nd hand traditional amplifier engineering, ie toroid transformers and hefty heat sinks, that are likely if nothing else to be more robust and if necessary repairable, like you'd find in 2nd hand amps by Randall, Crown, etc?
As a sub amp, I suspect you probably wouldn't notice any difference.
But let's say up to an active crossover at about 500 Hz, any experience or thoughts on their relative sound quality?
Thanks
