Three Mythical Creature’s to be exact. Dragon and Firebird both silver both have the 72v DBS. Thunderbird 10% silver wire no DBS. I’m sure the Thunderbird sounds great with out DBS but not as good as Diamond, Firebird, or Dragon with 100% silver wire. The Thunderbird HDMI looks to resemble the Audioquest vodka in design.
If I owned a PS Audio Perfectwave Transport I’d be tempted to trade in the Diamond for Dragon. But the modified Oppo and Spdif sound great with Diamond!
