Platter mat insanity

I was doing an idler upgrade to my 401 (more anon) and when finished used the Keystrobe disk to ensure speed. I use a 10" EP as a platter mat. I played a bunch of albums and it sounded fantastic. On the 6th side, I noticed I'd forgot to remove the 4" strobe disc. Duh. I took it off and figured VTA was responsible. So I lowered the arm to see if that made it sound so good. Nope. Put back on the 4" strobe disk and raised arm. The awesome sound returned. So air under the record removed haze, smearing, flattened soundstage and muddled bass; and made it so more musical.

I have tried several different mats on my G-401, an Acromat, the suspended design from the maker of Trans-Fi Terminator (which didn't seem to work well at all for me), and a solid TTW copper mat (along with TTW brass weight), and I always come back to, and stay with, the copper mat and brass weight.

I don't know what to make of your EP mat, though I could try using the strobe disc from the KeyStrobe speed setting system. May be worth a try, though.

Have you ever heard of the "Resomat", made by Trans-fi in England?  Contrary to most dogma, it raises the LP above the platter on a bunch of rubber tips. This permits the LP to resonate freely.  That mat has a loyal following.  So, maybe you are in a way correct about why the strobe disc effects an improvement in SQ, according to your ears.  Of course, be aware that VTA may play a role, in fact.

@lewm I tested for VTA. While it had some small impact, it was nothing like the improvements wrought from the 4" disk. The Resomat and Trans-Fi have sadly ceased business.
@islandmandan Dan, well aware of your setup! I’ve been wary of the weight of the copper as we’ve discussed a while back. I would be delighted if you can do the strobe disk test - don't bother with adjusting VTA initially. Just dig the opening up of the music!

Yes, noromance (by the way, does your moniker suggest that, like me, you are beyond your prime?), I'll have to get off my lazy butt and spin some vinyl and try your trick out. You never know unless you try, right?

Dan, as a friend told me once when I asked him if he was still interested in women, he may be old but he wasn't dead! Looking forward to your findings.
