Due to the fact that other 3rd party companies had been able to test their products with the sonnet echo adapter before the final release a customer of rme could expect more helpful answers than "not released yet." from rme.
Answers like " We try to contact sonnet to evaluate compability" would have been a much better way of customer treatment. (at least if rme really tries it :-) )
but now i am happy that i did NOT purchase a UFX during the last year (my 2 Multifaces were useless after my macbook pro had to be replaced by a new one due to hw failure) .
And to be honest : the way MC answered several month ago some questions regarding solutions to use the hdsp xpress cards together with the thunderbolt macs kept me away from selling my Multifaces and replacing them with the fireface ufx.-> A good customer relationship sometimes helps to sell further products ;-)
