Where do you live? You may be able to find someone on here who lives in your area that has either the YBA or the Brinkman that would let you come demo. From my personal experiences I prefer the YBA. Of the many different brands of high-end electronics I've heard, the YBA stuff has always been one of if not my favorite. This includes Krell, Boulder, Halcro, Moon, Conrad-Johnson, Sunfire, Proceed, Mark Levenson, and McIntosh just to name a few and not to say that each of these aren't VERY good manufactures. Its just a personal favorite.
Good Luck to you!
