Good job. A friend of mine brought over a set of Mark 2. Your review is consistent with what I heard. I thought they were very cost effective for their price. While they did not best my Audio Research Reference 160m they were not at all a slouch.
My new review for The Absolute Sound comparing AGD GAN amps with BHK300’s
I am normally best suited to be behind the camera, but The Absolute Sound convinced me I should try my hand at reviewing. In listening to AGD’s Audion GAN amps I compared them with my BHK300’s. This was done direct from the my Dac - PS Audio DS MKII with APS transformers, to eliminate any preamp interactions.
