OK, so I've installed this, got it working and listened for a while now. Not a massive amount to say, but I thought I'd post my thoughts nonetheless ;)\r\n\r\nI've installed it to a Super Scout Master signature, with a Dynavector 20x modified by VPI. That goes into an Ayre phone then a Music First pre, into Allnic power amp and finally to Avantgarde Duo speakers.\r\n\r\n[B]Installation[/B]\r\n\r\nFairly straight forward. It took me an hour, but I had drunk a bottle of red wine immediately beforehand so was proceeding with [I]extreme[/I] caution ;)\r\n\r\nInstallation requires that you snip your existing wires in the motor unit and on my unit, there was not enough slack in the wires to make this an immediately and easily reversible operation. Something to consider.\r\n\r\n[B]In use[/B]\r\n\r\nSimple and quite obvious benefit of improved speed stability, with all the inherent benefits that brings. Particularly notable is a more realistic representation of voices and acoustic stringed instruments.\r\n\r\n[B]Value for money[/B]\r\n\r\nIn my system I'm happy that this was a worthwhile upgrade. I could have spent slightly more achieving slightly less and still been satisfied.\r\n\r\nIs it an essential purchase? I'd have to say "no" - I was happy with everything before and I don't look back in hindsight and remember sub-standard replay. Is it a worthwhile upgrade if you've got a nicely sorted system? Yes.
