Hold on a second. Lets look at the geometry of a tonearm. The pivot point is all the way at the back end of the tonearm. So adjusting the height of the back end of the tonearm can make a relatively large difference in the Stylus Rake Angle (SRA) or the angle of the diamond in the groove at the front of the tonearm. Maybe as much as 5 degrees overall for a typical range of adjustment, and potentially more.
Conversely, the thickness of a record will make very little difference in the SRA because it is affecting things all the way at the front of the tonearm. Maybe as little as 1/2 of a degree overall.
So adding a mat may make a difference in a very sensitive moving magnet cartridge with a fine line or Shibata stylus, where adjustments need to be fairly precise. It will make no audible difference in your typical moving magnet cartridge.

Just read what vinyl guru Michael Fremer says about this.
"I said "why don't you ask him how he set SRA", which he did. The response was that it really didn't matter because as soon as you switch from a 120gram to a 180gram record it's completely changed the SRA. That is completely wrong of course. You would have to change the back of the arm 4mm to change SRA by 1 degree. At the front of the arm, raising or lowering it the difference between the thickness of a 120g and 180g record would change SRA by well less than a degree and I submit that no one can hear that small a difference, especially if your starting point is an unknown SRA!"
BTW - 4mm = .157 inch
Now a record mat is likely 1/8" thick or so, and it could make a difference in the height of the record off the platter, but more importantly it changes how the record mates with the platter, and dampens vibrations. Also, it makes little to no difference at all unless you are using a cartridge with a fine line stylus. That is usually found on MC catrridges, and more expensive ones at that. If you have a MM cartridge this is all moot.

Well I don't know who this Michael Fremer dude is, but I'm not impressed with his grasp of logic and basic geometry.
But then, you did say he's a vinyl guru.
RadioShack got out of the stereo business several years ago anyway, save for a few nick-nacky things. They used to carry a few good drivers and for a few short years some decent low end gear. But like many a big box stores they started staffing their stores with people who were willing to work for minimum wage rather than keep people around with any knowledge.
RatShack had a bum rap for decades and deservedly so but it usually had some gems amongst the rubbish. What always hurt that franchise was their best attribute - diversity; not specialized enough to be the definitive source for high quality in anything, but they'd always do in a pinch because they usually had everything. They were the 7-11 of electronics. The last few years they were reduced to selling cellphones and middling RC toys.
Just a note to BobM and Pr33t regarding a recent cart replacement. I replaced my Sumiko Blue Point 2 with a Dynavector 10x5 cart. Three weeks is still to short a time for breakin but a couple of thoughts. The Sumiko is a nice cart but there are a couple of things I wished it had done better. Channel separation and sound stage could have been improved. I noticed this while listening to ELP's Knife Edge. During the sweep near the end of the track, the sweep seemed to stall or pile up in certain places. Not a smooth left to right, right to left movement. The Dynavector took care of this as the sweep is now clean and free moving. On older pressings, the Sumiko seemed to flatten out the tracks whereas on newer pressings, it performed nicely. Some of the older pressings I used were, Bowies' Diamond Dogs and The Allman Brothers, Filmore East recordings. Older and newer pressings on the Dynavector sound great with alittle beef behind it. Great sound stage and no instrument is lost in the back of the mix. Again, three weeks is not enough time to make major statements about a cart but these are things I've noticed right away. The Sumiko is a nice cart, make no mistake. But at this point, the Dynavector is producing some great sound. The TT used is a Pro-Ject Classic Xperience 2, Olive.
The older I get, the better I was.
staun - glad you are enjoying it. Dynavectors are some of the best cartridges around these days. One suggestion, now that it is mostly broken in, go back and recheck all of your setup parameters again.
The suspension has loosened up and it likely needs readjustment (or at least double checking) for VTA and tracking force, maybe anti skate and azimuth.
Enjoy,
Bob

Congrats Staun. I am running a Dynavector 20X2H along with the P-75 phono stage and it is giving me by far, the best sound I have ever had from my vinyl. I don't know about the 10X5, but the 20X2H does a great job minimizing surface noise, clicks, etc. that the Ortofon 2M Blue didn't.

Staun, I can't remember what you are currently using. In the past, I've always used the phono stage in my amps. When I decided to get back into vinyl, I put some money into my equipment. I had my 30 year old TT tuned up, I replaced the tonearm and started with an Ortofon 2M Blue. I hated it from the day I got it. It was on the advice of the dealer with whom I had a lot of success in the past. (Can't win 'em all.) Luckily, he left town to open a store in Toronto so when I went back to replace it, I dealt with someone else who was a real vinyl nut. I demoed a few carts including the 10X5 which I liked. He said that for a little more $, I could get the 20X2H and the results would be really significant. I went for it but with the phono stage in my old Arcam integrated amp, it just didn't have the presence the 10X5 had in the store. So I shopped around a bit and found a guy in Toronto that was selling a P-75 MK 2 just after the MK 3 had been released. So what extra I spent on the cartridge, I saved by buying the previous version of the phono amp. My high output moving coil cartridge has the same specs as a moving magnet, so the jumper settings are the same for both. There is another setting for low output MC and a third setting is specific to Dynavector's low output MC. (Sorry, can't remember the marketing name for it.)
What I am getting is much more detail and better imaging and presence. With the Arcam, the sound was veiled and recessed (some people say it's akin to sitting at the back of the hall). With the P-75, everything is clearer and I seem to be sitting at the front of the hall now. It's not over the top by any means as Dynavector has a relatively tame presentation compared to many others. For me, it's just right. It's not a miracle worker though. I was listening to Tull's Heavy Horses and that recording is just so flat and lifeless, nothing could bring it to life. On the other side of the coin, I have Joe Jackson's Blaze of Glory which is all digital and the shrillness makes it practically unlistenable. But when it's a good recording, it's bliss. Last night it was Ralph Towner's Solo Concert and the detail and image I was getting was just fantastic.
Now, the P-75 MK 3 is probably in the $800 range. Used is probably half that. If you want to go lower, you can check Audiogon for used phono amps. Names like Rega, Cambridge and Pro-ject run between $100 - $250.
