Peterayer,
I certainly agree with your point that "everything from the cleaning thru to the interconnects leaving the phonostage should be thought of as a [vinyl] 'system'."
I have had for many years a Nitty Gritty record cleaner. It was certainly a great improvement over my previous ineffectual efforts to clean vinyl going back to my pre-high school days. However, results with the Nitty Gritty were well short of perfect.
I have not owned a VPI 16.5. However, this past year when I re-committed myself to vinyl (we had replaced our old transport & DAC with an Ayre C-5xe and my wife was arguing that we should get rid of the TT and sell our vinyl) and decided that the time to replace the Nitty Gritty was long overdue, a local dealer was kind enough to clean 10 of my most treasured Mercuries, Shaded Dogs and Ray Charles albums with his 16.5. The result was a decided improvement over my old Nitty Gritty, but still far from the level of improvement I was seeking.
I continued to seek advice from some of those whose knowledge, objectivity and opinions on analog matters I greatly respected. Their advice was to swallow hard and part with the big bucks to get a Loricraft. I did so reluctantly, but from the first record I cleaned with it, I was and continue to be very happy with my purchase. Most of my LPs are now as quiet as my CDs, as difficult as that may be to believe. I would recommend the Loricraft to anyone who has a substantial investment in vinyl and plans to continue to play it. I am very confident that the Loricraft will not only allow you to enjoy to a far greater degree the sonic wonders of your valuable collection but will also be a much better partner in helping you to preserve it for future generations.
Good listening,
Ed
