Fosgate Signature Phono Pre question

I do not believe it is switchable. I am in the US and mine has printed 120v 60hz on the back.

I do not own the Fosgate. It is a dealer demo that I have had for the last 3 weeks or so. I am waiting to hear the ARC Ref phono 2 which he is getting in. That said I like the Fosgate a lot. I have seriously thought about buying it.

But it can be very sensitive to noisy tubes. You really need to use very low noise tubes. I have a Clearaudio Innovation Wood Compact with Universal arm. The cartridge is a Benz Wood M2. The Benz is a medium output moving coil. The Fosgate has an organic feel while still being very detailed. I have also tried the Moon 310, Nova Phenomena and Sutherland 20/20. The Fosgate is by far my favorite.
