Well I contacted Dr Choueri directly with the Email you provided. Did it on May 11 which was six days ago, and crickets. All I really wanted was the answer to two simple questions:
(1) What was Theoretica's upgrade policy? Specifically, I wanted to know how much I would be charged if I started with the introductory version and wanted to upgrade to the Audiophile or the Audiophile+, or the Pro Edition at a latter point in time.
(2) I also wanted to know if it was possible to purchase one of the upgraded packages without the Babyface interface, and if it would be possible to make the system work with another interface such as a Motu M4.
In think those are both perfectly reasonable questions. If they're not selling a lot of units, then their lack of responsiveness could have something to do with it.
Their system has been in the market for years, and even highly informed audiophiles barely know about it. Small wonder if this is how they treat potential customers.
