I have had a pair for about 15 years and I have modified them quite extensively with rewire, bipassing the fuses etc and new capaciters. I have kept the original drivers. Removing about half of the internal wadding helped also. They are suberb speakers and when positooned correctly and driven by high powererd quality amplification they can be quite suberb. I currently drive them with 150watt Krells. In terms of absolute control and tranparency they may not be up there the very best but they seem very neutral and the truth is that I can't bear to replace them. Whernever I have had any work done to them by HI-FI stors the feedback is that these people are are stunned at the sound. They need to be raised slightly and set on solid bases I use concrete slabs.
