Quick update: After a few hours listening with the AZ's into the Mid/Tweeter amp I wasn't convinced it was the right place for it. For some reason it moved the stage back a bit more and warmed things up a bit but it didn't quite gel with the rest of the system how I had hoped so I swapped it with the Pro Silway MK2 which was between Dac and pre and this did the trick. With identical pro Sil 2's going into each amp and the Az Matrix 2 handling the whole signal from Dac to pre, the synergy just hit the nail on the head... the stage was still a bit further back than before but the air and space was subsequently deeper as well. There was definitely a move to the warmer side of things and hence the occasional trace of sibilance I had noticed on a few select recordings was now gone and replaced by a more natural rendition. This was most noticeable on the all important "T's" and "S's" in female vocals... the leading edges were rounded just enough to nip the edge off but the detail managed to remain... a difficult balancing act that made all the difference for me. So in a nutshell, in my experience, the AZ Matrix 2 will add a bit of warmth when compared to the Pro-Silway 2's (remember, just the 2's, I have no experience with the later editions), it also seems to add some deeper air and spaciousness and doesn't emphasize the detail quite as much, yet doesn't make you feel like it's missing. A trace more rounded on leading edge transients which will probably be a good thing in many systems, as in mine, although probably not for good in an already warmish/or slow/ rich system. The AZ Silver is likely to be the better match there. Hope this helps, just my $.02. Happy Lissn'n
