Hi Bill, sorry for my late reply.
I heard the Micro Be with the Gryphon Tabu but it was very long time ago so I can not give you any details. While looking on the net for this Tabu integrated (I could not remember its name) I stumbled on a few sites saying that the Gryphon Tabu is identical with the NAD Silverline integrated which was sold at a fraction of the Gryphon price (2000 vs. 6000 euros) and which according to NAD was an improved version of the TABU. Gryphon on the other hand denied this. I find such stories very disturbing. (I also read here on audiogon that Focal uses 1.5$ caps in the crossover of the MicroBe.... and that one can significantly improve the MicroBes by changing those caps.)
Coming back to the Gryphon, I spent around 3-4 hours (by myself with my music) with an all Gryphon system (i.e. mirage pre, colosseum power amp, mikado cd player and Trident speakers). While the sound was not bad at all my impression was that the company strategy is to impress people with their exorbitant prices and strange looks rather than sound quality. But then this is not the first time when I had this impressions about extremely expensive systems which I can not afford.
Regards,
Paul
