Turntable mat options

You are likely to get as many opinions here as there are mat options... Lol.

I feel you can do a lot better than the felt mat for sure, however as the Rega does not have adjustable vta your options may be a little more limited.
Yes you obviously can adjust the rp8 vta by shims or spacers under the arm itself to raise it for a thicker mat but a bit more of a pain than vta on the fly system.
You can buy fairly cheap examples of cork and vinyl mats on eBay.
I suggest buying a few and trying them and see what you like.

On one TT I prefer a mat that’s a hybrid of leather and lead.
On another I prefer using a 10" 78 album as a mat.
You don’t know until you try!
Relatively cheap fun.

I will be trialing a new mat in a couple of days made by a member right here and will update with results.
I expect it to be a winner!

Hey Chip,
I have had just about every type of mat you can think of and I really do not think the mat makes much difference. I think you can prove this to yourself just going back and forth between your felt mat and no mat. Do use a record weight or clamp. I do hear a slight difference when certain types of record hold down systems are used such as vacuum hold down and the Walker/SME style system that uses a very thin shim at the spindle and a screw on record clamp that forces the record into the platter. I hear an improvement in mid bass definition. 
As far as just a mat goes the felt is fine. If you see one that looks better to you and makes your turntable nicer looking that is fine. The only thing I can think of against felt mats is that if you do not have a dust cover they will collect dust whereas other mats you can just wipe off. Don't fall for the ridiculous marketing claims that come with most mats.  

Right... Mats make no difference.
Of course.
Why didn't I think of that......

I've had a Rega P5 in the past.
Regas are great for simply enjoying a record.

Sit back and enjoy it,unti you're ready to upgrade to the P8/10 and a better phono stage.

No one here, has your ears.
