Have never upgraded firmware for my mains DSP5500 upgraded to 24/96k. Is the firmware upgrade worthwhile regarding processing resolution? The others don't seem like a big deal. My center channel is a DSP5000C.

DSP5500 Product Firmware Release 5.40 (2011-10-31)

Software Fixes - Useful - May be useful to upgrade but not essential
Aux legend becomes SLS and VCR3 legend becomes Aux
Aux/SLS source defaults to 4C comms type
Optional support for M80 remote
Improved processing resolution
Better integration with two way speakers in theatre systems
Crossover improvements

DSP5500 Product Firmware Release 5.20 (2007-11-16)

Software Fixes - Useful - May be useful to upgrade but not essential
Improved crossover.

DSP5500 Product Firmware Release 5.10 (2006-08-02)

Software Fixes - Useful - May be useful to upgrade but not essential
Volume control responds according to system address - relevant to some two-room systems.
Latency through DSP speakers unified at 7.5ms.

I find it a huge improvement on my 5500HC
It completely changed the sound if you ask me, in a good way.

Mids/high’s are better.
Voices sound more natural, and biggest change the sound is hanging mid air in front of the speaker.
Hard to explain, but it gave me the same kind of effect with 2.5b9 firmware for the 568.2 processor.

Timing latency is now also the same with my DSP33’s, which made a good improvement in surround content.
