I have an Aune X7s desktop head phone amp. This is not the current X7s Pro. It's still balanced (with a single-ended output) and Class A. I have the original packaging. Balanced output is via 4-pin XLR, single-ended is with a 1/4" TRS. Input is single-ended only: RCA connectors.

Price listed is net to me. Buyer pays actual shipping to be added to the listed price.
