Bel Canto ACI600 vs Black EX Sepates


I'm trying to decide between these two Bel Canto beauties for an office setup. Both are similarly priced.... The ACI 600 is an integrated version of the 55k Black system. The Black EX separates are the more budget friendly system.

Whatever I choose, they'll be driving KEF Reference 1's.

I'm looking for advice/impressions from people who have owned these systems or heard them at an audio show/dealer. What are the pros/cons of each setup?

Please, no advice on different electronics or speakers.

Thanks!

Just came across this older thread, just wondering how everyone is liking their Black / Black EX systems.  I am considering trying out the Black EX Integrated with my Martin Logan speakers.  I know Bel Canto has great DACs and I am really interested in an all-in-one solution to simplify things for the time being.
I know the Black EX integrated very well. I listen to it daily and still love it. Yes, I'm a Bel Canto dealer, so you can take it with a grain of salt if you like, but an absolutely fantastic piece.

I've been using the Black EX integrated w/a pair of DeVore Gibbon Xs now for about 18 months and really love it. (WyWires Platinum speaker and power cable). Continues to sound fantastic. It really is hard to imagine budgeting 15k for separates (amp, pre-amp, phono, DAC, streamer) that do the same thing at the same level (plus all the cabling).
