Use of a 110 VAC to 230 VAC Step-up Transformer for CD player.

I have no idea

See my previous post on this subject. A simple step up transformer will work fine. I have had a lot of experience doing this over the years without incidents or degradation in sound quality.

Shouldn't I be concerned about the CD player being designed for 50 Hz , but  running at 60Hz. In other applications this may not be as important, but with high end audio gear I just don't know. Thank you for responding

I am trying to see if the manufacturer will sell me just the power supply, if that is all that needs to be changed. They are saying to send the unit to them and they will do it, but that will take weeks or months and add about another $800 - $100- to the cost, which I am trying to avoid. I hope that ypui are correct mgattmch. Thank you

Sound quality will suffer why would you buy a foreign unit anyway??
