I really enjoyed the review for all the info and analysis. I actually have owned the Audions for about 1 years now and have gotten the upgrade tubes as well. The claims are true and the change in the faux tubes do change the sound signature very much like tube rolling.
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.
