So it sounds like you’ve made your decision, to keep the unit for now & eat the $200 if you have to?
I evaluated similar technologies at length back in the 90s, when I was a tech journalist & consultant, and ultimately found those precursors to work best with (and sometimes ONLY with) beamy speakers positioned to optimize nearfield response. Not surprisingly, the quality of the experience varied greatly. The two systems that gave me the best results were ESL-57s and a Sonigistix planar-magnetic desktop system -- for just those reasons. Obviously, I was already living with a narrow sweet spot.
This technology is still interesting to me today, and earlier this year, while actually considering a purchase, I researched in depth the B-SP’s underlying design concept and Theoretica’s claims. What I found was that, although details have changed, the fundamental idea remains the same.
Back in the day, installation meant at most measuring the filtering characterics of each listener’s pinna and/or optimizing speaker positioning to mitigate unwanted reflections. Straightforward, but sometimes time-consuming.
So, not having had a hands-on opportunity myself, I had to ask: how elaborate are these "implementation" procedures you’re talking about? And how hard is it to fine-tune this implmentation to provide satisfactory results?
Given that so many people have had such different experiences with Theoretica’s purifiers, I’m eager to learn what you find with your particular speakers.
