The TDM uses a 48 bit stationary point. In theory the 32 bit floating point should have a greater flexabillity. In addition the convertors in the 002 are a close cousin to the 888/24 but do not come close to the 192's Power is the major issue, that is what can be done with a particular system. I have used an 002 properly and with 20+ tracks have seen no "flattening", but you must be aware of the available headroom and this is where we seperate the men from the boys. The 002 can not even begin to match the power or sound of the HD systems. the 001 is not even in the same league. the 002 will do many of the things a Mix system will do with the exception of Larger track counts more DSP and surround which has been discussed to death here on the DUC. DIGI must offer at least 5.1 in order for the 002 to remain viable, but the Mix systems are old technolodgy and shouldn't bear any weight here. Although they are capable of far more DSP than the 001/ 002 they are a dead end. The HD systems are already in thier 2nd incarnation (ACCEL) and if we are talking about HD vs 002R there is almost no comparison but there is a huge price gap. Only you can decide what works for you and your clients. I often start by flushing out ideas at home using an 002 but when I get the basics together I will bring the idea in and work on it with an HD system. I hope I have clarified this a little more, my real world experience does include 001/002/m-box/mix+ and HD and accel. I am trying to lay before you the facts without coloring them too much. If you need the power of HD spend the money it's a great investment. On the other hand if your needs are not so grandios and you and your clients can't tell the difference use the 002. As always it comes down to pocketbook vs. need and available production methods.
