One only used demo includes optional Headphone Amp, remote and original packaging with balanced to headphone jack adaptor. The Headphone amplifier option cost $1000 more than the A300 without. Sounds brilliant on my Sennheiser HD800 headpones

A Swiss-army knife of Digital Audio: The Soundaware A300 is a DAC, SD card transport, USB bridge, network streamer and optionally, a balanced Headphone Amp. It's Bluetooth compatible, supports native DSD and is a fully balanced circuit with pass-through or digital volume control by FPGA. Specs similar to the D300 (Not D300Ref).

High-end sound quality with dynamics, detail and body.

6moons.com: "Major personal kudos for the inclusion of a card reader which outside Soundaware we previously only saw with Resonessence. SD cards are a cost-effective solution for top-quality playback of locally hosted files without WiFi radiation, network access, computers or USB improver boxes. When fitted with the headamp circuit, the A300 makes for a reference-grade nightstand system that'll drive HifiMan Susvara planars to perfection, no extra components required. The same goes for an advanced desktop system where the A300 will drive active speakers."
