Darren, you are correct, it did not cost much to try this much ballyhooed product. Your business model is a good one, outside of placing advertisements in the forum section of Audiogon.
The Triple AC Enhancer certainly did change the sound, more bloom, almost a tube like midrange quality. However, this came at the expense of rolled off highs and bloated bass in my system.
Thanks for the offer, but I will take a pass on your Corelli, as I have not had much luck with passive filtering devices. I also tried a couple of High Fidelity MC-0.5’s this year, they didn’t work out well for me either. They made the sound-stage height and width larger, but at the expense of stage depth. My system turned into a large, flat two dimensional stage, with musicians sitting right in my lap.
The only passive devices that I have found to offer more good than bad come from Jack Bybee.
