Up for sale is a PS Audio GCHA Headphone amp. This is the upgraded model with both balanced and unbalanced inputs.
Unit is a year old, and has seen very little use. As it turns out, I am not a big fan of Headphone usage. The unit does sound great. Also has a USB input as well.
Original MSRP: $1000.00
Asking $300.00 shipped to lower 48 via pay pal. Pleas PM with any questions.
