I finally got to audition the DAVE for several hours here in Texas. I was impressed and I was unimpressed. Allow me to explain: I brought as much of my desktop rig as I could to compare my current setup with the equally British iFi iDSD micro against the DAVE, fully expecting the DAVE to kick its ass. Well, the DAVE did...and it didn't. With PCM and with the crossfeed set to 0 the iDSD and the DAVE were a wash. They sounded very, very close to the same, and the salesman agreed. There was no extra resolution with the DAVE, no special width of depth gained, nor was there anything within the redbook audio that I had never heard before. The caveat is that it took the combination of the iDSD micro and my SPL Auditor to achieve what the DAVE was doing just by plugging my HD800s direct to the DAVE's headphone jack. However, the crossfeed, at 1 & 2, on the DAVE sounded awesome, which is something that the analog crossfeed circuits on the iFi products have not been able to do. The iFi crossfeed is very subtle, and yes, while it sounds natural, it's not much of an effect, while the DAVE crossfeed sounds equally nature, only more pronounced, as if you are listening to a different system. But is the DAVE's crossfeed worth 11k or 12k more for PCM? No, I don't think so. DSD audio with the DAVE was something different. Neither me nor the salesman heard a difference in sonic quality with DSD files played through the DAVE, but they sounded just as good as the redbook presentation. Ironically, given the name of the iFi product, the iDSD micro, the iFi product playing DSD sounded harsh and edgy going through their proprietary analog filters. It took playing DSD against the DAVE for me to hear how brittle and unresolving the iFi is doing DSD. Anyway, since I listen to 95% PCM, there's no reason to get the DAVE. There just isn't. As an aside, I also auditioned the Berkeley Design Reference Alpha DAC2 against both of them, and the Berkeley killed them at every turn. I've never heard digital like this...ever! The reproduction the Berkeley gave the sound was slightly forward; nevertheless I would take that natural sound at every turn. @bigfatpaulie & @romaz, when talking about the M1, was it the M1se that you guys had owned or just the standard model?
