Step down transformer for a turntable


Are there any concerns related to the use of a step down transformer on a turntable?  I am wondering if the use of the transformer in any way diminishes the sound quality of a turntable?  I am considering buying a 100v turntable from Japan for use in USA. Would be an upgrade to my analog side. Let me know your thoughts.

My Japan market Victor QL-A75 runs wonderfully with a step down transformer, it draws 16 watts. Like others have said better to have more watts than needed. Avoid the cheapest ones. The one I use is rated for 1120 watts continuous power, and I plug two devices into it.
