Yes agree , then we migth ask how inportant they think their own spec is . drmatt wrote: > Indeed.

Would be interesting to se more test of such DAC's . I've would not be surprised if they are different and further that some of settings do produce small audible differences . Some filter settings combined with some DAC and you hifi may produce undesired side effects . Due to sighted testing and the intellectual corruption gone several rounds in the industry , some "voodoo designers" may actually manage to bodge such a well understood thing as DAC and produce kit that do sound different , but not for any good reason.. It would be healthy if the magazines that do measurements could point a finger at clearly broken stuff instead of producing more smoke and mirrors and FUD usually trying to explain away the strange performance with some claims of unorthodox design principles and hidden unmeasurable variables that must exist due the excellent result in sighted testing ;) Happy to see Archimago do his measurements. It would however help tremendously if MQA themselfs produced a test signal suite and publish it officially so that anyone could test compliance in MQA branded products . -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
