Sure. IMHO a lot of matching a particular NOS Dac, or any other component for that matter, still has a lot to do with your system first. In particular your speakers first and foremost.Thanks for the insightful information. I have been interested in a nos dac based on the many comments I have read about them.
I found the Project, and Maverick are a excellent match with both of my systems (mainly do to my speakers), and it fits my particular listening goals. The Great Heils/AMT3's are able to extract more then enough detail, so I don't find my self wanting any "more" in this regard. Because the balance is right on par.
And so my thinking is, given the relatively high efficiency of the AMT3's, a NOS DAC would work well with other high efficiency types, Klipsch, Altec's etc. The nice thing about the vintage speakers is most let you adjust the various mid/high frequency drivers if the need arises. In their current listening environment my AMT3's are on 'normal' setting.
Again, as mentioned they key is with the DAC Box S FL is to let it get warm, as the sound really comes together, and just flows. The Muse is that way also to a point, but the differences between a cold FL and a warm one are much more pronounced, they sound very different.( Both Dac's run on 9 volt dc. The first gen Fl's (with no selector switch) ran on 16 volt dc).
It mentions the need for warm up in the literature from Project. Let it warm up!!
