My friend gave me this catalog from his dad's work and it had a bunch of audio stuff. He said he could get anything for half price and I thought it would be all crappy brands. There was some good brands (MTX, RE, Pioneer, US Amps) but there were also a lot of brands I have never heard of. Could you tell me if these brands are good or bad please?
