What are the audio differences you hear with turntable Mats.

@wrm57, Please accept my most sincere apologies.  I have suffered 5 major strokes and there are times when I don't comprehend/understand or process thoughts very well.  It can be very frustrating to me as well as to others... so for that I am very sorry.

I have read your posts and I greatly appreciate you taking the time to share your thoughts and experiences with me and others.

When I read your previous post, you had written...."It works perfectly well with weights and clamps other than the one made by Oracle. Personally, I like the Origin Live Gravity One (out of many I’ve tried), which weighs almost nothing but sounds terrific on the Lenco."   To my mind, that tells me that you have successfully used the Oracle mat perfectly well with several "weights and clamps" but you prefer the Origin Live Gravity One which weighs almost nothing ( but yet, it is still a record clamp/weight, is it not?)  I did not see anywhere in your post where you specifically said that the Oracle Mat does not need to be used with a record clamp/weight.

So, with my challenged brain... I guess I didn't understand that what you may have meant to say is that because the Gravity One weighs almost nothing, that it would be the same as not using a clamp/weight at all.  Is this what you were implying?

It is helpful to know that a record weight/clamp is also not needed to be used on the BA mat.  Thank you for that.

Please forgive my "slowness" in understanding and don't give up on sharing your thoughts and experiences with us, as I and others do indeed appreciate your contributions.

Best wishes to all,

Don

no_regrets, I do use a both a weight (about 250g) and a clamp (SOTA) with Boston Audio mats (two different turntables).  However, with a bare platter surface that is concave or dished as mentioned above, I don't know how that would work out as the graphite is not very flexible, if at all flexible, so it would not readily conform to a concave platter surface. And there would be a remote danger of the BA mat shattering if too much pressure was applied at the spindle over a concave surface.

For those looking for a great reflex clamp, don’t forget about the two made by BDR (Black Diamond Racing): a solid 1-pc., and a 2-pc.. Made of Carbon Fiber, with 1/4-20 threading. They show up on USAM used every once in a while for about $150.

@lewm , thank you for sharing your thoughts and experiences with me and others. I think I will keep a watchful eye out for a used BA The Mat.  If I can't find one in a few weeks, I'll order a new one to give it a try 😁

Best wishes,

Don

With regards to mats. Different is easy, better not as much. Analog playback systems have so much individuality built into them its hard to predict the outcome, or what the listener will prefer. You will change the sound, now whether you like it or not is a different question.
