SME IV vs V

If you have both then why not mount both and find out. Sorry just couldn't help myself.

Anyway I do have the V and have never heard the IV but the only diff is that the V has the spring VTF dial which gives you dynamic balance and also the damping trough is standard on the V.

The bearings are a little better in the V:

"Many of the component parts of the Series IV are similar, if sometimes less rarefied, to those in the V. For example, bearings of ABEC-3 tolerance are used instead of ABEC-7."

This link has a pretty detailed difference list:

I had both and agree the differences arent to big

Thanks for the link Mofimadness.

Rccc, could you give your impression of the subtle sonic differences?

OK, so I started reading the link Mofimadness supplied, and the IV uses copper wire, instead of the silver wire found in the V. If I wanted to upgrade wire, what are my options and how difficult is it?
