I do not know enough about this stuff to really comment on a technical level. However, If I took the time and care to put something as extensive as this together, I want it the way that I want it. Period. I myself am very meticulous, not having it the way I specified and not changing it would keep me up every night regardless of whether it sounded better changed or not. Change it yourself and be done with it. You will sleep better. Finally, I hate suckey customer service. To bad for them, word of mouth is the best, or in this case worst, reference you can give.
Sorry for your issue,
