Listed is a Bryston BHA-1 balanced headphone amplifier in good condition with the 17" faceplate, internal analog power supply, and power cable. This is a high-end headphone amplifier retailing at $2495 USD. I have to sell it since I realized I don't use headphones much anymore to warrant keeping this amp.

It does not come with the original box and some paint for the text and screws have worn off over time, but the amplifier itself is in perfect working condition and sounds phenomenal. Very neutral sounding amplifier with really standout tight bass impact and detail retrieval, and is made with 6 fully discrete Class A Bryston operational amplifiers. The amplifier also uses balanced dual-mono circuitry, and has the relatively rare left/right balance control built in.

In regards to how much power it has, the BHA-1's a strong enough headphone amplifier for about 98% of headphones on the planet except the most power hungry ones with:

Load at 32ohms:
High Gain - 9.65 V OUT @ 2.9W
Low Gain - 4.84V OUT @ 578mW

Load at 300 ohms:
High Gain - 10.8 V OUT @ 390mW
Low Gain - 5.40 V OUT @50mW
