I'm not trying to insult you, or anyone else, but the difference between hearing (a physical response to sound waves) and perception should always be kept in mind. I hope you can get your loaner.

Merc has a really cool solution to the double bass issue (see above) and if the digital (A->D->A and D->A) part of the 950 is clean that would be a possible solution for me. The noise measurements soundhound took really shake my level of confidence though.
