Yes, Indeed. I had a home demo of Gryphon Diablo 300 and it was just fantastic amp. I did like it very much and saving for it. Superb bass, smooth highs, darkish sound with a lot of mass and thick thick midrange. It produces a wall of sound, very very big soundstage. My speakers are Harbeth M40.3XD, DAC - Mola Mola Tambaqui.
