Well, here is my new All-SP Tech Ultimate Mundorf 5.1 system. It consists of:
* a pair of SP Tech Revelation MR1 MK IV (my new name since the latest wonderfully musical tweeter mod was done to these, first in the US I think) with the Ulitmate Mundorf external crossover boxes
* a center channel Continuum AD with custom stands and Ultimate Mundorf external crossover box

* a pair of Continuum AD's with custom stands and custom Intermediate Mundorf crossover boxes as music surrounds (sofa's not in the way, just looks that way; ultimately the back of the room will be on 8 inch risers that are level with the foyer entrance))

Bob and Jason are my heros!!! They took the long 5 hr drive from LaPorte and arrived around 8:30pm last night. After many hours of setup, tweaking, modding the Revs, polishing the cabinets, wiring the crossover-to-speaker umbilicals (Bob's custom Zero Resonance cabling used internally of course, but the external umbilicals weren't ready in time so I'll break-in the crossovers with the supplied zipcord for now), munching on pizza, Cajun wings, drinking some liquids of various toxicity..we finally got down to some listening. First up was my very familiar 2 channel demo playlists so I could confirm that the Rev mods were indeed an improvement....and they were in spades! Then we listened to some 5.1 Dark Side of the Moon and Beatles Love. WOW! First time I have 5 identical drivers, and boy does it matter. I'm gonna demo tonight with the LFE sub out of the loop and see what the Revs do in true HT mode...I bet they hold their own.
Again, this is just a synopsis. I'll write a full review once everything settles in, breaks in and the Zero Resonance cables arrive.
Thanks again to Bob and Jason for their products, support, and above-and-beyond customer service. Nothing like having a speaker manufacturer that you think of as "family". And thanks to buddy Rob for his help too.
