Just to be clear Tony...your estimate for a CP750 is about $1000 high. In Victor's situation, I would definitely recommend the CP750 and keeping the CP55 with all the fixins since he already has it. The CP650 is far too limiting as an all-in-one. The only time we use them is if someone has one and is going DCinema (and even then, Dolby has a special quite often that makes using anything other than a CP750 quite expensive). The other time we use a CP650 is if one is putting IN a film system (yes, we still do that!) or is replacing an unreliable system.
As to the CP55/65 parts being obsolete...which ones? The 2:4 decoder (Sanyo chip on CAT 150E or the Analog Devices chip on the Cat 150F)...is about the only one I know of. If so...big deal, getting a "prologic" decoder isn't really that hard and one can stock pile Cat 150s at this point. As for making a replacement Cat 150...just looking at the Cat 150F one can see they are down to putting a chip on the board (and that was about 10-years ago)...any maybe a regulator or two. One need not be too clever to fabricate a replacement Cat 150, if the need ever arises.
Datasat took a different approach with their AP20...they fabricated a "film" board so that one could add film to what is essentially a DSP based box.
So I stand with, rather than obtaining a CP650, I would add a CP750, JSD100, DCPx00 or any one of a bazillion DSP based processors. This is NOT a knock of the CP650 however one should think of it as a FILM processor that CAN play DCinema...if you bought one for film, Congratulations, your transition to DCinema will be at most, a card away. If you don't have one yet, then it is likely not your most economical nor most flexible solution in a DCinema world.
