The September 2012 issue of Hifi'Zine is now out (just in time) and it contains my review of the BSG qøl. Perhaps most interestingly, BSG offer a manufacturer's comment after the review that contains details I'd not seen elsewhere, and also announces the successful patenting of key ideas in the design.
As you can tell, I enjoyed this rather unusual new product. I remain unclear on how exactly it does what it does but the results are impressive in my system. I know the qol has given a lot of people reason to doubt but talking about it is really no substitute for hearing it. I made that point (edited out of the final version) but really, trying to form a view of any component, not least one as different as this without hearing it for yourself is an exercise in frustration. No matter how much you want to dismiss it or embrace it, you need to hear it, ideally in your own rig. BSG make this possible with easy 30-day returns, a trend that is welcome in this day of limited dealerships. They will be at RMAF in October but show conditions, especially given the well-documented volume difference when bypass mode is engaged, cannot substitute for hearing it in your system. Hearing is believing, but never more so when the mechanisms involved are out of the ordinary.
