Hello! Up for sale is my lightly used Quicksilver Audio Headphone Amplifier. Works great, looks cool, and has tons of power (7V RMS). I am the only owner. The amp will ship with instruction manual and warranty card.

I have had great success driving many headphones with the Quicksilver including 8ohm headphones to 300ohm+.

Sound-wise this amp has uncanny speed, clarity, and slam without coming across as harsh. It sounds great with everything I've thrown at it, but it sounds absolutely killer with the R70X imo.

Included are the stock sets of tubes (JJ EL84 and Chinese 12AX7B), which imo probably sound best overall, but I can include some very nice tubes for modest additional cost.

Among the available sets are:

12AX7:
JJ ECC803S x2 (modern)
RCA Long Gray Plate W D Getter x2 (vintage)

EL84:
Genalex Gold Lion x2 (modern)
GE x2 (vintage)
Raytheon x2 (vintage)
