The Oor and Hypsos will be sold only as a pair together. The Oor is really fantastic and the Hypsos increases its performance. It easily powered any headphone I used with it.

I'm downsizing my audio gear and using only my DAC's built-in headphone amp.

Payment is Venmo (PayPal an option too, fees covered in the price).

I'll cover USPS Priority Mail or FedEx Ground shipping (tracking provided). Shipped only within the CONUS.

Due to the holidays, shipping may be slightly delayed after receiving payment, but I will do my best to ship them asap.

No trades.
