I sold it because I didn't (and largely still don't) foresee 7 channels, and at the time I was looking at it as freeing up money within my audio budget. But honestly, if you are expecting logic regarding a hobby of passion, you won't get it from me! If I still had the 2007, I certainly would not look twice at the Monolith 5.
But rationally looking at my audio buying habits, there is decidedly a hint of audio addiction. Fortunately, I recognize it as a vice and don't let it cause financial stress (I've saved more money by driving econoboxes then I'll ever spend on audio...unless it gets worse!
) at least that is my attempt at justifying/normalizing it!
