Our shop just received the latest edition of the Bricasti M1. I had sold our demo to a friend/customer in Arizona about a six weeks ago and the replacements we delayed. Well it took about two CD's to recognize that the new filters are just awesome. Sound staging with amazing front to back layering. In a word, WOW. The latest edition has a volume control and a remote is forth coming so you can plug the M1 into your amplifiers. Haven't tried that yet but a customer of mine has and was thrilled. Might be able to send you a demo to try out. Where are you located?
