Dear Ethos, those are all great questions.
The Cambridge receiver has been lowered to spur sales, as this unit does not have Atmos nor HDR yet, I think the management of Cambridge felt that lowering the price would make the CX 200 go from a good deal for the superb sound quality to a must buy at that price.
I talked with managment and they said that an HDR software upgrade is in the works, but who knows with these companies.
One great review of the CX 200 from I think Home Theater magazine said it is the best sounding receiver under $5k. we concur only the Arcam or the Audio Control with Dirac are a match for this piece and those products are $3,400.00 and $4k.
Personally I feel that Atmos is a sillyfeature that most people don’t have the extra money or space for the extra speakers.
The Cambridge sounds better than the 787 we had all three in our showroom you might be able to see that shot in our
video
https://www.youtube.com/watch?v=1NPIn3pEmI4NAD T787 on the top, CX 200 next shelf and we had the Primare SPA 22 in that shot, we must have sold our demo Anthem 720 which was usually in that room.
Our current rack we have the CX 200, Audio Control Maestro M9, and the NAD T758 with the Anthem AVM 60
The NAD has great punch but isn’t as clean sounding, the NAD has a warm, punchy sound, the Cambridge wide deep soundstage, great clarity.
Room correction is a nice feature that can improve the theater experience but to me it is not a make or break issue.
You should give us a ring I am sure we can assist you in determining the pros and cons of all of these models and considering we sell Arcam/Audio Control, NAD, Cambridge, Pioneer Elite and Anthem I think we are in a great position to field any questions.
