Kenny,
I don't know which amp. It was a big one with meters, something from their recent lineup as he only began carrying the brand about a year ago. I didn't take notice of the exact model because I couldn't stand the system for more than a couple minutes. The room/setup looked professional and well done, so I'm not sure how much that contributed to the poor sound. I've only heard GE speakers at this retailer, the Triton Ones and the Triton Fives, neither sounded good to my ears. The Ones were running off the McIntosh amp and the Fives were running off an Onkyo Integra AVR. Both setups sounded shrill and bright with weak bass. The Monitor Audio and Revel speakers he also sells were far more tolerable in the treble region.
Honestly, I can't imagine how anyone could like the GE speakers if they typically sound like the ones I heard. I haven't heard any Tektons, but after my experience with GE, I'd risk ordering the DI's if I had to choose between these two options. Have you looked into Salk Sound? I almost took a gamble on their Song 3 towers.
