Edge Electronics Signature One Preamp A/C-D/C operation!

The Signature One Pre-amp is rated 8/10 for age and unknown provenance. I purchased it used from Upscale Audio in 2017, so I don't know the entire history of the unit, however, it looks and functions beautifully, with the exception of the remote control which is erratic at best, but the remote does “work”. As you can see in the photos, it comes with the remote, manual, an aftermarket hospital grade power cord but NOT the original box. The "scratch" on the top is a digital artifact so I took pics from different angles to show it isn't real (if that makes sense)~It was designed for and sounds best with the NL-12.1, which is currently listed as well, I will make a discount if a buyer purchases both of these items.
In addition to running on A/C, the preamp has the ability to run on internal batteries (D/C), running on the internal batteries drops the noise floor quite a bit IMO. The preamp itself can also recharge the batteries by turning a knob on the faceplate. The replacement batteries are not expensive @40-60 dollars depending on your place of purchase. There is a photograph of the batteries so you can look them up yourself to confirm price, I found them to be less expensive on a stand-alone battery site vs. Amazon...
