Closed: iFi Pro iESL energizer for electrostatic or dynamic headphones

I already sold my other iESL that was mint, the same day I posted it! I sold it for $1500.

I'm on the fence about selling this as having the additional bias voltages is handy, but not needed as all the electrostatic headphones I have right now are 580V.

I did a lot of playing around with this iFi Pro iESL, so I can't call it mint. I bought it from bhphoto, it was drop shipped directly from iFi, and the original shipping invoice is included (out of warranty I'm sure though).

In fact, full disclosure:
I'm an electrical engineer and like to play with all things audio, so I even took this one apart and soldered on it. However, I put everything back and filmed a video driving some of my dynamic and electrostatic headphones. It functions great and sounds great.

The video is on my youtube channel due to size:


Terms of sale:
Must have a PayPal verified address, where shipping/billing addresses match. I will not ship out of the US or to a third party international shipping center.

I will ship using a traceable method, and as fast as reasonable (shipping cost and paypal invoice fees are on me too, but must be CONUS or I may ask for you to cover a portion of the shipping cost).

Thanks for looking!
