That might be true for some people Ian, but having benchmarked an absolute level of quality through the (ringless) 7200SEs, I can say that I'd be prepared to live without the rings if I could obtain the 'speakers for several �000 less than new SEs.
What are the sums anyway?

If I go down the road of the clamp rings (that is to replace the 7200.2's), then I'd probably have to consider the 8000SE's at the same time. Either way, it's an expensive journey.
If it's only going to give a 5% improvement, I think there is little point. If the difference is far higher, then lord help me.
There are used 8000.2's currently on HH for �12k, add the SE upgrade at �11,500 gives a total of �23,500, new 8000SE's �44,000 (I think) all full retail prices, clamp rings effective cost �20,500.
