Great amp for someone who doesnt mind some patina and wear, and only cares about great sound! Heavily sun-faded on mostly the left side, right side is largely black still. The volume pot is bent a bit off axis. Sounds great, this amp is just far too large and overkill for my needs. Includes pictured tubes, unknown if they are the original or not. Includes wall power cable, and power passthrough cable, no audio cables. Will be packaged securely with bubblewrap, styrofoam, heavy duty box, etc.

For sale is a perfectly working woo wa23 Luna headphone amp and pre amp. It is within factory warranty. My asking price is the lowest in the aftermarket for Local pickup and free delivery in Tri State. The local pickup is preferred due to the high risk of shipping tube gears. Shipping would be considered via Zelle and I just purchased new box from Woo, yet I’m just too scared of shipping. For local deal, I would be gifting high quality Kimber PC and Dana RCA that beat all other costly cables I tried and I tried a lot. I way much prefer it to the technical and treble focused Wa33 elite for the thick, full and thunderous and masculine bassy sound, which is non fatiguing but musical, organic and analogue The best deal you don’t want to miss! Selling due to I’m gong electrostat, Otherwise I way much prefer it to Wa33 even elite. Sound demo: https://youtu.be/0FnUTVMJ3Y8?si=vHwtYGWsM7At-yqK https://youtu.be/XQQHG2hHGUQ?si=57yriqF1cgYLtYgd
