Hi, just saw your post from last summer re: my 1.6-based system. Looks like you're doing nice things here! I'll bet the Rogue monoblocks were a huge upgrade. I'd suggest you keep working on your digital source if you can. Cambridge Audio offers a good value, but the more signal you feed your Maggies, the happier they will be :)
I'm still using a Classe .5 that sounds decent but is on its 3rd transport and can't manage to track on a lot of my CDs. I A/B'd it with the Ayre CX-7e on a pair of 1.6's at my local audio store, and the difference was gigantic in terms of pure sound, soundstage and detail. So the Ayre is definitely a winner, and I've seen some Esoteric gear on Agon lately for reasonable prices. Esoteric is just a stunning product line. And of course there are many other contenders.
I'm mightily interested in Mapleshade's Maggie stand, http://www.mapleshaderecords.com/audioproducts/epiphany.php. Simply running my speaker cables on top of their Triad lifts made a considerable difference in my system's clarity; I'm pretty sure the Epiphany stand would change the game entirely. The one poor thing about the 1.6's to my mind is their woefully unstable, non-damping feet.
I'd be interested in keeping up to date with you, let me know how your system is doing.
