How to change voltage on Esoteric K05X? Or is step down transformer ok?

Hi,

I would be grateful if somebody could give me some advice on the following, please.

Around five years ago I bought in Japan an Esoteric K05X Sacd player (Japanese voltage). Now I have moved to South Korea and the voltage here is 220V. I am running the unit on a voltage step down converter that I brought over from Japan.

my questions are:

1. in terms of sound deterioration, how ‘bad’ is it to use a voltage step down transformer in general? 
2. I wonder whether the Esoteric K05X can be modified to run on 220V? If so, how? Does a dealer do this? Can it be done by somebody who knows electronics, ie is it a matter of doing ‘only’ some soldering?  I looked into the unit and I could see the ring transformer and on the main board some writing showing 250V. 
Thanks for your help!

cheers,

Steffen

Not all step down transformer created equal, A good one will not degrade sound quality, in some cases, an isolated step down transformer can improve SQ.

Depends on the model, some model just simply move connectors, some need to replace transformer, ask your dealer for advise.

Can you provide a link to some close up photos?
