120/115V vs. 100V

I just successfully transported my Musical Fidelity A3 CD player from the US to Hong Kong. I'll also be bringing over an A324 DAC as well, in a few months.

The CD player has an input voltage of 115V...so to get it to work, I purchased a step-down power converter to get the local voltage down from 220V. However, I was only able to find one that converted to 100V instead of 115/120V. (Presumably for Japanese electronics.)

I've read posts about pre-mature electronic failure if the voltage is above certain tolerances. What about the case when a 115V component is only receiving 100V? Also, is there a sonic impact? I can't tell, because I am using new speakers and a newly modified amplifier that hasn't burned in yet, all in a new room.

Thanks!
