Woo Audio WA22 Headphone Amp 100 hrs

Woo Audio WA22 Headphone Amp

$1600.00.  Buyer pays
pal fees and shipping CONUS.

I purchased this new 1 year ago for $2000.00

If I'd listed it 6 weeks ago I would have been able to claim it 10/10 mint.

Extraordinary sound but I'm just not a headphone guy.  I can't sit still.

Less the 100 hrs on the amp.

Included are Woo Audio standard tubes for this model:

1 5U4G Rectifier Tube

1 pair of 6SN7GTB Drive Tubes

1 pair of 6AS7/6080 Power Tubes,

Original packaging.
