RUPERT NEVE DESIGNS RNHP Headphone Amplifier

This classified is for a Rupert Neve Designs RNHP headphone amplifier. The RNHP is a high quality headphone amp built for studio and audiophile use. It features XLR, RCA and 1/8" inputs and a single 1/4" output. The volume control is silky smooth. This amp drove my 'phones (Beyer DT880 600 ohm, Beyer DT990 600 ohm, Beyer DT1990 and HiFiMan HE-560) nicely, with authoritative bass and a silky smooth midrange and treble. The amp comes with a 24V "wall wart" power supply.
This amp is about 3 months old and in like-new condition. I purchased it as a temporary solution while relocating for work and now that my belongings have arrived, no longer require it. It was purchased from Sweetwater for $499.
Shipping is a flat $25 to any U.S. address in the lower 48 via insured UPS ground. Shipping to any other U.S. address will be calculated separately. U.S. buyers only. This amp will ship from The UPS Store in Janesville, WI. I will pick up PayPal's fee.
 IMPORTANT NOTE: My job requires long hours and as a result, it may be a day or two from receipt of payment to shipment. I will do my best to expedite shipping and will clearly communicate a shipping timeline at the time of purchase.
