Step down transformer (220V to 100/110V) or buy 220V version of Shindo preamp


I really need to buy a Shindo preamp. a) Should I go for a original 220V Shindo preamp (harder to obtain, no local Shindo dealer here) or  b) get a 110/100V version from USA/Japan and use a step-down transformer c) Or get the Shindo dealer to alter the 110V to 220V.

questions:
1) At this level, is there sound degradation if I use a step down transformer?
2) The Shindo dealer will change the 110V to 220V but it will be done by a US tech not Shindo, I wonder if it will lead to some loss. Since soldering and change of resistor will happen. If that's the case I might just buy the 110V version from him.

Any thoughts on using step down transformer in general, does it lead to sound degradation?

I ran a Japan voltage (100v) Luxman amp with a step down and it worked great. Just get a quality on with double the power rating your amp is rated at. That’s the power usually on the back of the amp as you want the usage power rate not the out put power. My class A 50wpc Luxman was happy on a 1500w step down and ran silent and cool.
