Selling my Aesthetix IO Signature phono preamp with a single 110 volt power supply. I am the original owner of this astounding phono amp. I recently had the unit serviced by Aesthetix. The boards and tubes in the preamp are completely new. The boards and tubes in the power supply are approximately 1 year old. This unit, essentially, is a new IO Signature in an older style case. I have the original shipping boxes and can ship the units wherever Fedex delivers. The cases have a few minor signs of use, but the electronics are new. I might consider a trade for a high end solid state power amp. Buyer pays shipping and paypal fees.
