I went from DSP5000, through DSP6000 & DSP7200 to the DSP8000SE Anniversaries.

I've tried DSP5500s, DSP5200s and DSP7000s and they've never stuck. Each has limitations and issues.

I bought the 7200s hoping they would improve the DSP6000s, and was disappointed. It wasn't until I upgraded them to SE status that I heard the improvement I had hoped for.

DSP6000s when fully serviced can out-perform some of the newer DSPs, it all depends on your space and budget!

The DSP8000SEs are a major upgrade on everything but in saying that, I still use other studio monitors for 'critical' listening.

Cheers,

Steve
