Hi Heath,

Good heavens, 105 dB!!!. Don't!

Use 75 dB or 85 dB--whatever is comfortable. It's somewhat arbitrary anyway.You want the test signal to be loud enough (especially with our ears' insensitivity to deep bass as levels diminish), but not so loud that it's uncomfortable. I've been using 85 dB SPL at my listening seat because that's a fairly typical "average" SPL level for much of my listening.
