How does a step up transormer affect sound-


Guys I just got set of amps that run on 230 volt- I got a pair of step up transformers to convert to 110- does this affect the sound - I can either use the step up transformers or - run a pair of 230 volt lines or send them back and have them set up for 110 volt- They sound good to me using the step up transformers BUT I want the best sound possible so which is the best route to take- thanks so much-

George's advice is really sound- if you exceed 50% of the rating of the stepup/isolation transformer, it will degrade the AC power by adding distortion to the AC line.
Transformers affect sound quality, even the very expensive ones, best to avoid them if you can!
