Garrard 301 - Project

What specifically do you not like about the DAS plinth?  I believe yours is constructed with a slab of MDF on the top.  That's how he builds the plinths with the radiused edges because he can't wrap the radiused edges with veneer.  If it were plywood, you'd see the layers of ply at the radius.

Do you think the top MDF layer has any negatives?  Is the TT chassis coupled to the MDF layer or is it coupled to the next layer of plywood below the first layer of MDF?  I believe DAS mentioned to me that the TT chassis actually sets on the MDF layer, but it was a long time ago and I may be misremembering.

I am very familiar with much of what occurs in the UK with Idler Drives, and the Power Supply in the Link is a New Brand and New Model to me.

As stated in other posts, the LDA, is a very difficult design to surpass.

MDF is basically wood dust and glue. The reason MDF has no purchase when you screw into it is because the glue is the most expensive component, and the manufacturers only put enough in to just hold the wood dust together and no more. It is designed as a very low cost material. I worked for a number of years in the timber industry.

When you buy something like DAS plinth you are buying weetbix wrapped in xmas paper.

This doesn’t necessarily mean it will sound bad, it simply means you are buying a plinth that’s full of wood dust and glue.

Personally on my 301 I used a hybrid of compressed bamboo ply and birch ply. Bamboo ply is harder than Maple, can be CNC’d ( I did mine myself ) and provides a stable platform that won’t warp over time. It is not pretty though, which appears to be important for some folk.

I do not use wood veneers because they are not stable and eventually you can see all the joins and I personally can’t stand that. If I wanted a wood finish I would do a shindo style laminated solid wood block plinth.

"When you buy something like DAS plinth you are buying weetbix wrapped in xmas paper."

That's a little harsh, no?  I think most (maybe all) DAS plinths are 100% birch ply (not counting the veneer obviously) with the exception of the ones with rounded top corners that I mentioned above.  Those have one layer of MDF on the top.

Look at these pics.  These are all birch ply since they do not have large radiused top corners.  Why would you call that a weetbix wrapped in xmas paper?  Not trying to argue at all.  Just trying to understand what you're saying.  Seems like pretty solid construction to me.

Bamboo Board with three tiers as the minimum and compressed on both planes, is a improved Board for intrinsic Damping/Dissipation Properties over most of the usual board types seen used for Plinth construction.

A 401 listened to, mounted on a Compressed Bamboo Board Plinth, is my most impressed listen I can recollect. 

Compressed Bamboo Board as referred to above does not cost too much. As a ,material it can be further enhanced for the attractive intrinsic properties, by applying thinned oils for it to absorb. I recollect seeing Shellac referred to as well as a Treatment to improve the properties, all good on my camp, as aesthetics are also being dealt with as well.
