I believe AGD dropped him as a dealer some time ago. Some short time after that event OCD came out with a video saying some Jeff Roland class D amp was better.
I got my Tempo from Verdant.
AGD Tempo in the house
It is very interesting to spend time with amps. You go to shows or even go to someone's house and listen to and amp and because it isn't on your gear and in your environment, it sounds good but it is insanely difficult to judge vs other gear.
So AGD is a brand I had been flirting with and finally a customer asked for a demo so I put in my order and a few days later the Tempo arrived. I dropped in into my system and all I can say is WOW. It has all the grunt required to drive my Vivids. Is warm and sweet with an extremely wide sound stage.
Even fresh out of the flight case, (no box here) it didn't sound digital at all. This sounds closer to Class A to me than Class D. I have not heard a different GaN at this point but I am fascinated by this and how good it sounds compared to other Class Ds and even Class ABs.
The other surprising part is this unit is about 1/3 the size of a normal component. I know I am a hair late to the game with GaN but damn, is it ever too late to celebrate a product.
