I'm curious about the THX certifications. Does that get in the way of a strictly music set up? In other words, would I be paying for something I don't want and, as it is designed for home theater also, is it an infringement on my needs?
Just because it its THX certified, doesn't mean it is designed for HT use only. And your not paying for it. Parasound is by paying THX for the certification. So consider this a bonus.
I have had Parasound THX certified components in the past and it is excellent, high value gear for 2 channel application. I wouldn't hesitate getting another HALO amp.
