Using Maple Butcher Block Under a Turntable

Asahitoro. Don't bother with granite. Use 4 inch air dried maple from Mapleshade. I had wrote a long post but it got lost in a bad connection. Oh well. 

there are footers that came with my butcher block audio shelf that are rubber and cork.  they seem to work really well

I got my butcher block from Butcher Block Acoustics the other day. It took about 6 weeks because I had mine done at a custom size to fit my Solidsteel WS-5 wall shelf. It came with cork/rubber pads for feet, which I am using to support the block on the shelf. For the turntable I have changed out the spikes on the feet for a set of isoAcoustics Gaia III feet (normally used for speakers, and I have the Gaia II on my Dyn C2s). It looks and works great. I am going to try out some HRS Nimbus pucks instead of the provided cork/rubber feet to see if that makes a difference.

With regards to the maple from Mapleshade or Butcher Block Acoustics is this hard Maple or soft Maple?  If its soft Maple it is not as dense as Cherry or Black Walnut.  Hard Maple is very hard and I would imagine its resonance is at a higher frequency than any of the other three I mentioned.  

I googled Mapleshade and they use ambrosia maple which is any maple that has been infested with the ambrosia beetle. I don't know what exactly the type of maple they use and maples on the Janka scale vary quite a bit. So just guessing which maple, just look at what type of maple grows in Penn Amish country.

Brown maple is prevalent in Amish country with a hardness of 950 on the Banks scale which can go from 350 up to 4380. Its a soft maple from a quick look and guess on the world wide web

I use this block ontop of Mapleshade Isoblocks:

I have two turntables, a Mofi StudioDeck that features sprung-loaded feet and a Triangle Art Concerto with upgraded platter; the platter is much more massive than the standard model platter and the base+platter easily weighs 40 lbs.

The MoFi seemed to like being on the cutting board with the Mapleshade Isoblocks isolating it from the rack. It didn’t seem to like Rollerblocks under the cutting board and it hated having Isoblocks under the turntable’s spring feet. I assumed the feet were designed to work with a certain amount of feedback from the surface they sit on.

The Triangle Art gear have little rubber nub feet. I can’t say that being on vs being off the board makes any difference but I haven’t tested this extensively since moving it around is a pain in the butt. I’m torn between putting the large TA speed controller box on the board or off -- currently its on.

As for hardness, I have the Butcher Block Acoustics end-grain 3" Maple block, and they rate it 1450 on the Janka scale. I am using it under a ~40 lb Clearaudio Ovation (with 2350 gr of clamp and outer limit ring).

dwette with that Janka scale rating it would be hard maple. I sell hardwood lumber and was just curious what the preferred type seemed to be. Thanks for the input.

blueranger ambrosia maple is almost always soft maple (Red or silver).  I have never seen hard maple with Ambrosia beetle damage before, only Red Maple.  I have sold hardwood lumber since 2000, but I guess anything is possible in mother nature.
