I have been curious about the THX eval of AVRs. I was surprised to see some lower level Onkyos with THX certs. I don't put much value in a THX cert for higher end units as they all meets the needs, but I was surprised some of the lower units could meets the requirements. Or, does that mean THX criteria is just that easy and their stamp of approval really is just marketing hype? Your quote sounds like real evaluation, if 18A, 12.5A, and 6.2A are significant hurdles. Anybody care to explain the significance of those tests to use lay folk?
