onix used to be a british company that made fine-sounding gear. i have one of their old bwd-1 tuners, which is fantastic - easily competitive sonically w/anything sold today - including the top magnum dynalabs... their older amps/pre's were also fine warm-sounding s/s gear.
the company was sold several years ago; the amp you're referring to is made in asia - likely a proton knock-off. some models are the *identical* models as proton stuff, w/different name on the front. not 100% sure, but i believe the amp you're referring to is one of these... decent budget gear, but nowhere near as nice as the old onix electronics.
