This one is fresh in from just North of Seattle. Well, uh, er, its mine actually. The reason for the post is that I'm using the slate plinth for the first time in quite a while. A few years, actually. And guess what -- it's good this way. Noise floor goes down quite a ways while in the slate.

I dig the look of slate. Non-reflective and rugged looking. Industrial. We visited a slate quarry / mine while touring Wales a few years back and I have to admit the were a few moments when the audio-dork in me was fondling (sp?) chunks of slate wondering about hi-fi applications.
BTW, I really like the look of the naked 301 chassis. Any plans to paint it or are you going to leave it nude? It matches up well visually with the rugged slate.
Hi Waxxy.
I think I'll leave it bare for the near term. I like it looking kind of 'roughed-in' if that is the right term.
re: slate. Ime it is definitely not the same as any other solid rock I've tried. Granite rings with a long sustain. This stuff does something else. Not sure what. But it seems to soak up drive train vibes quite nicely.

plinth yourself? I ask, because I purchased several pieces of slate at Lowes in hopes that I could work the material myself someday. The material is neavy but also prone to cracking. I was planning to grout a few pieces together after all the cutouts were complete.Slate is certainly a very dead sounding material like soapstone. Surprisingly, the density of slate is almost identical to marble, even though I have always thought that marble is very dense and hard and was not dead sounding. I am guessing that the internal structure of the two materials is different.

Slate is a more homogeneous material than marble - Marble gets its patterns from other materials, such as sand, Iron Oxide, Chert and the like - this breaks up the material such that it has boundaries within the cut slab/pieces. While slate can have occlusions - typically its value is in homogeneity where as Marble's value is in the 'movement' the patterns of impurities.
-It should also be recognized that Marble covers a wide range of materials from calcite and dolomite to metamorphosed limestone.
Other than water jet cutting- Slate can be cut with diamond tools and copious amounts of water - it is also relatively soft, so can be polished/honed with Aluminum Oxide (AlOx, Al2O3) or Silicon Carbide (carborundum(r) SiC)
Happy Listening

Did the 'slate' thing on My thorens in '72 Worked OK ..no more no less.
Kept it as plinth for a few years, eventually went back to OEM as it was easier to house/move and I tired of slates' dust magnet attributes as well.
Not noticing a significant loss as result of it's replacement TBH.
Granite ..Bluestone.. Lotsa Dense rocks about to experiment with
A Headstone shop can carve out a plinth to design for passable prices.
Should one feel the Lust.

The slate has to be much thicker than any flooring tiles you could find at Lowes. The slate I have came from a quarry in Pennsylvania. Circa 2007. Story about it at link below.
I wrote a .dxf and with some help from J.Weiss at Oswald's Mill, got mine water-jet cut. The slate quarry lapped the ends into a good flatness. But the top and bottom faces were rough. I've done some lapping on those but there is more work to be done. I'm kind'a lazy, I guess.
re: density of slate. I don't know exactly what it is about this material, but in thicker pieces it tends to soak up idler drive train vibes quite nicely. Good isolation from surrounding support structures as well.

cheap and use several layers of slate tile held together with the Lowes provided grout. Of course, the grout may eliminate any of the advantages obtained with a single thick block of slate, and leveling the top layer of one of those Lowes tiles may be impossible. I visited our local stone shop in Alaska, and they are unable to provide any worked slate slabs.
