Hello Everyone. I'm new to this circle and wanted to be perhaps the first owner to report on the Insight power amp. I think I'm the first to receive one. I design speaker crossovers for individuals and for Jim Salk. Although I don't accept payment for any of that work, several years ago someone insisted on sending me a Hafler amp in appreciation for crossover work I had done. It was a Van Alstine rebuild, and has spent many reliable hours doing subwoofer duty in my HT setup. I often have people stop by to listen to one of my speaker designs, and I've always used a big-name (and expensive) amp in the music system just so no one would claim that I was cheaping out in the electronics department. It sounded fine on most speakers, but really couldn't deliver the goods driving the Salk HT3 speaker, which is a very low-sensitivity design. It would often just give up and head for protection mode when I played Wagner at full cry. Very frustrating. Anyhow, Frank learned that I had one of his old Haflers, and very sternly admonished me to send it in for a redo. I wasn't sure what that involved, but Frank is not to be ignored, and I finally shipped it to Minnesota. Back it came a couple of weeks ago with the complete Insight upgrade. I got it into my music system a few days ago to test out a new 3-way design in comparison with the HT3. (I have a volume compensated A-B comparison preamp that allows for valid comparisons between designs of widely differing sensitivity.) After a few preliminary tracks, I gingerly placed my Wagner disc in the player, ramped up the volume, and waited for the HT3 to cut out. But--all I heard was the best sound I've ever experienced with the HT3. I stayed up way later than I should have Monday night listening and to and enjoying Frank's handiwork. Can I say that the Insight sounds better than other amps on less demanding loads and at lower volume? No, because I haven't conducted a valid controlled experiment, and those are the only kinds of results that count in my book. But I can say that the pricey big-name unit is now driving subwoofers, and the Insight isn't even breaking a sweat delivering the goods to my HT3. Thanks Frank!
