Hmm.... well, it'll work but it's certainly not the ideal partner. DSP33's really belong to the 500/5000 generation of products and as such do have a different timbre to the 5200's which are derived from 8000/G series. It depends how much space and budget you've got. A single DSP3100 would work better if you can't get a 5200C in the system. Maybe even a 5000C Mk2?
If the 33 is the only solution just spend a little while tweaking. Maybe even drop the centre for music?
