The AGD I heard at Axpona from Alberto the designer room they sound good. If Iam correct Caladan speakers are using atmasphere class D they are good as well.
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.
