The “other amp” on this table is, I think, equally impressive — the GSX Mk II Frank Iacone reviewed earlier this year. At nearly half the price of the Blue Hawaii, the GSX is one of the finest headphone amps being made and one that will actually drive any (non electrostatic) headphone you care to throw at it, including the beastly Abyss AB-1266.
Shown at CanMania, the GSX was entertaining the full suite from Audeze, HiFiMan and the luscious TH-900 from Fostex.
There’s really not a lot to say about Headamp — their two headphone amps are crazy-good and comfortably laugh at mere mortals from their lofty perch on Mt Olympus. If you can, you really ought to try them out. Either one is a game-ender.
