I am no longer listening to headphones. Thus, I have for sale . . .
1. Audeze Deckard pure Class A Headphone Amp in near-mint condition. Original box, packaging and all accessories. It has seen very light use in a pet-free, smoke-free listening room.
2. Sennheiser HD-650 headphones. New OEM headband and ear-pads installed. Original box and packaging.
3. Cardas 16' headphone cable -- custom terminated for the HD-650s and with a full-size jack on the amp end.
The Deckard is quite powerful at 4w/ch and can drive inefficient 'phones as well as difficult planar magnetic headphones. It also includes a line-level output, so it can be used as a bare-bones preamplifier. Finally, it includes a 32-bit 384kHz USB DAC (which I've never used).
$375.00 OBO for everything. Cash or Zelle accepted.
Here's a typical rave review of the Deckard: https://headphone.guru/the-audeze-deckard/
