SME 309 vs SME IV - sonic differences?

I had a 345 (basically a 309) and a V. I didnt hear a big difference between them using a high resolution cartridge ( ca insider ) and clean phonopre ( custom tube ) The removable headshell is very convienient on the 309 and I preffered using that arm and never missed the performance difference of the V.

I currently own a modified RB300 (Kerry counterweight / Incognito rewire) - I am receiving various recommendations pointing to Morch as a good option as well - goshhh this is though!

Thanks so far for your feedback.

Right Rccc I went from a V to a VPI 10.5 for the better.

I should add that the performance of any arm is going to be cartridge dependent and the sme works well with a fairly wide selection of cartridges. The big selling point of the V for me is the ease of set up. I change cartridges alot and can be up and running in a couple minutes. If the V had the removable headshell it would really be easy.The removable headshell also allows for azimuth adjustment.

Jfrech--I also use a IV.Vi arm, but mine did not come with the damping trough. My trough was an add-on option which wasn't cheap. Maybe the 20/2 table comes complete with the trough, but I don't think that IV.Vi arms come with one.
