Purchased new a few weeks ago. Life has happened, so I'm forced to sell even though I've really enjoyed this as both a headphone amplifier & pre amp. Comes with everything included as if it was brand new. Price includes shipping and paypal fees, so it's a huge discount from the $1499 new USD price.

Here's the official Product website:

Feature packed, and everything works well:

• Class AB headphone amplifier, which was the main reason I bought it. Sounds excellent.
• Class D speaker amp 2x100w with speaker impedance detection
• USB, Toslink, SPDIF, Bluetooth, Phono, and Analogue RCA inputs
• Pre-amp, headphone, and speakers outputs
• Can use a remote control via IR or bluetooth phone app

You'll notice my reputation score is 0 as I haven't sold on Head-Fi before, but if you click on my profile you'll see I've been active in the community for several years.
