Well it took me a year to buy a separate amp, on account of I had to buy a new house first. Built a home theater in the basement, with acoustics as a priority.
The amp is a VTV 7 channel class D with Hypex modules. It is 700 W into 4 ohms for the front 3 channels, and 250 W for the 4 surround channels. As I was kind of expecting, it was not a huge notch up in sound quality improvement. A notch to be sure, just not huge. I guess the Integra's internal amps were getting the job done pretty well. But if I ever decide to upgrade my Arendal 1723's to speakers that are hard to drive, I'll be ready.
