    I had to break out the Achroplat again. I was curious how things would sound with the Grado Sonata and the Moon 110LP since this has been the best analog combo I have had. I remember liking it with the Benz MC Gold but changed my mind when listening to the AT F7.

    Last night I put it back in use. So far so good but I will listen longer before I comment further.

    Part of what has me interested in platters again is the Groove Tracer Delrin platter. Clearaudio and SOTA use Delrin platters. The claim is that since it is made from the same material as the record it interfaces well. Of course the same claims were made for the Achroplat.

    The sound from spinning vinyl last night was tighter more focused bass and a more detailed and layered midrange. I have not listened to enough records to comment on the highs. The upper frequencies sound brighter but not hard like with the AT F7. Of course a change in IC's might help.

    I do not know if I will try a Groove Tracer Delrin platter. I did not buy their subplatter and when I called about the acrylic platter he was not sure about the fit. I thought if it fit the Rega glass platter my DeepGroove subplatter should fit.

    So for now I will be listening to the Funk Firm Achroplat again. I need to decide if this is better than the Rega glass and Ringmat combination with the Grado Sonata/Moon 110LP.

    What problem are you trying to solve?

    Transmissivity of stylus tracing noise into the platter ?

    Which implies transmissivity of floor or table noise that got into the platter then being transmitted into the record ?

    How about a peek at "Noise & Vibration Control", Leo Beranek, graph on pg 412 for starters....

    Or- better record to platter isolation?

    Stylus tracing 'noise' from the record groove would seem to be very low.

    Uh really I am just trying to have fun. There really is no master plan. Many years ago I bought the Rega Planar 2 for $450. A nice sounding budget tables with some excellent design. Then I began to discover aftermarket parts to improve the performance. I was hooked and wanted to see how much improvement various tweaks would offer.

    Lately my interest has returned to platters after reading on several sites about Delrin. Of course seeing Clearaudio switch from acrylic to Delrin has furthered my interest. I read one review who said if you wanted to use acrylic on a Rega you will lose the ecitement and end up with a table sounding like a VPI. This new platter will probably be my last tweak since I cannot imagine anything else I can do for the table. Once I have taken it as far as it can go I will need to buy a new ttable.

    Speaking of tweaks I need to get back to my latest. I had posted before about an edge in the high frequencies with the Achroplat. I use the Deepgroove subplatter but the Groove Tracer subplatter has three dots on it that look like rubber. Then I began to think if the Achroplat was designed with the idea of it resting on the Rega plastic subplatter? The Achroplat directly on the metal subplatter may not be the best idea. I bought some rubber bumpers used to protect tabletops from scratches. I placed 4 on the subplatter and then mounted the Achroplat. Whoops too tall and then I remembered thin corners on my Sanus Euro stands so I robbed some of them and put those on the subplatter.

    Now I have changed the VTA a little and created a better interface than the Achroplat sitting directly on the Deepgroove subplatter. The hard edge of the highs seems to be gone. Of course I cannot say if it was the change in VTA or the damping between platter and subplatter. Interesting tweak to raise the platter instead of the arm for VTA. Ringmat had a system where they supplied discs with their mat to raise the record on the platter to tweak VTA.

    Yes I have fun with my Rega.
