[QUOTE="n2audio, post: 6595634, member: 540940"] Geez FJ -- you're surely aware of the multiple scientific double blinds done over the years concering this issue with the results continuously disproving all the voodoo you're spewing. I'm sure all those tests were flawed in your eyes, but if you want to continue down the path of analysis paralysis please take it to PM. The rest of us are just fine listening to the music despite the price tag.

I was running a Lanzar Opti100.4 bridged to my components at 180x2. Simply because my comps are rated for it I wanted to run something that could get 250 to them. I went with one of the Opti4x400d's - which is VERY similar design to the PA full range D's. I like the amp. SQ has not been an issue. Power is substantial and the amp has been reliable. My only complaint is that I have a high pitched noise issue since installing the new amp. Not a problem at higher volume, but when it's low enough to talk over naturally the whine is painfully obvious. I've tried a soundgate noise supressor w/no luck. Looking like an internal amp issue so that's something to take into consideration. It could be an isolated problem with my amp. [/QUOTE]
