Merlinm3, if your question was directed at me, I apologize for the slow response. I forgot to check off ’follow this thread’. I did fool around with the non-Oracle acrylic mat more after my post. I found the best arrangement was to place the washer on top of that mat. It sounds very good; but I prefer the GI. A tad more ’body’ to the sound. I may try some tweaking - rough-up the platter side or tac it down with some Duco that can be easily removed. And it is nice to be able to play with matching mats with cartridges. The GI with my dynavector and Denon, the acrylic with my Shure.
I have another question for the experts. I recently came into possession of the felt mat that Oracle sold with the Alex MK III and MK IV. It is by far the nicest felt I’ve ever seen or heard, a 3 ply affair consisting of soft felt/stiff fiber/harder, smoother felt. It is difficult for me to tell if there is much difference in SQ from the GI. My question is, why do you think Oracle made the switch? Does it mate better with the MK III & MK IV, or was it a cost savings compromise?
Does anyone have any insight?
