Hi audiodreamer, I have another question that might help narrow down the recommendations a bit. What decoding are you looking for in a new receiver that you don’t presently have? Actually could you post the model of your HDTV also?
Also with sony trinitron 30" HD 1080i would I benefit from blu-ray or upconversion.
I don’t think Blu-ray would be worth it right now but since you are using a CRT which may not upscale/up-convert everything thrown at it you could see improvement from up-scaling in the receiver.
