I above all would like to resolve all the concerns people have. Indeed the platter could be made less heavy, or more so if required!! Unfortunately I only have a Tektronix 475 scope and am not set up with all the measuring equipment needed to produce the measurements required. David among others has. Perhaps in the future HFW will take on the challenge.
What I have done is to design and machine a totally new platter which I know has illiminated most of the shortcomings inherent in the existing one and which all of you were looking foward to since the release of my High Precision bearing. I guess what we need now are some listening evaluations. I honestly do not believe that a large mass of electronic data and measurments is really going to mean a great deal to anyone, as the numbers will be to small to be meaningful or even to be accurately and concisely measured. As Tony has suggested any differences may be infinitely small and therefore below the mean noise threshold of the masuring device.
There is a particular user in the US who is using my platter with two copper mats plus center weight!! That make the total weight about 10Kg!!!!! and his initial response to me is very impressive, however it is not my position to pre-empt any comments he may post in the near future. He is probably taking his time over doing a series of subjective listening tests.
In order to resolve this impass I have suggested to Dave that he provide the platter to someone like Martin or Chris or Marco so that real listening tests can be conducted, perhaps using a series of specificly chosen records from Jazz, vocal, through to classics and in particular Piano.
I can undestand the concerns of all, the platter is not an inexpensive addition to the SL. However Dave and I are looking at ways to get the price down.
