I had an MP500 a couple of years ago.
In my system it gave a very lively presentation, "full on" everything all of the time which eventually became a bit tiring. It's hard to say what was missing or exactly what was so wrong but ultimately I couldn't live with it - so close and I still can't properly figure it out, but it just wasn't for me. Closest I can get is that maybe it was just a tad too toppy with too much "energy" trying to escape. Masses of detail flooding out.
I'd say if your system needs livening up this would be a great cart to try. Probably very sensitive to VTA adjustment.
