Wiring for 240V provides the benefit of *balanced* power; a great thing to have when you can do so. Aside from having half the current draw, noise floor should be significantly reduced. All of this may not yield the specific sonic improvements that you are seeking, but it certainly is not going to hurt anything in the least.
105dB SPL is just getting started at my house; I can do that with 2 watts/channel & still have about ~20dB of headroom. We can peak out >125dB SPL in the sweet spot, as measured with a lab grade meter, but no one can stand it that loud.
