One turntable with two arms, or two turntables with one each - which would you prefer?

In motorsports engineers do not like to try other things if what they have works. 

We create our own densified wood to our specs. We consolidate it at a higher psi and are hold times are longer. 

This makes it even more stiff and rigid. 

Who cares. Buy the one which is the best bargain

Why are you posting here - this is the thread for those who think a bit of floobydust and magic material will turn their Thorens 160, Garrard sp25, Teac into the best TT on the planet - bar none.

Some wag here thinks panzerholz is hard - on my CNC machine it is so soft it cuts like butter. Engineered quartz cuts like butter too - these materials are epoxy in reality. 

But what do I know - I've machined, drilled, cut, tapped,  CNC'd both.

Corian was trialled by a few TT guru's back in the 80's and never took off. Maybe this is for the baby boomers who want the 80's back along with their bell bottomed jeans and paisley Viyella shirts.

Now compare this to $16000 pounds for a phono cable from LFD that has a lovely electrostatic inducing plastic shroud, big chunky metal connectors so those micro wires know what a real man looks like and contains an assortment of different wires based on listening over 30 years, and of course they can voice them for you - you can have Freddy Mercury on helium, or Dolly Parton sound like Nat King Cole - now thats a real audio high end product.

Panzerholz is a material like any other. It has it's uses in places which require good rigidity and high damping, like tonearm wands for low compliance cartridges and turntable motor boards. No magic, just engineering.

One turntable with two arms, or two turntables with one each - which would you prefer?

An Inquiry of this type is able to suggest that a New Plith is a requirement.

One turntable with two arms: This as a method has seen many Bespoke Built Designs to suit an individual's specific needs or wanted aesthetic. 

or two turntables with one each: This can have various permutations, where one of them is for the use of Two TT's of the same design used with different Plinth Materials and the same Tonearm and Cart' used for both.

Either of the above, to suit one's specific needs, can require a Bespoke Plinth.

Plinth Materials are always going to surface when an Inquiry lends itself to potentially having to have Bespoke Equipment at hand to realise the method proposed.

@syntax Your statement is correct, My Granite Plinth which weighed in at 9 Stone, was produced as a design using professional services from a Stone Mason Company. There was no Middleman's mark-up, for the era it was produced, it was quite expensive, from recollection approaching £500, I'm sure another £500 was able to be added if Purchased through a Dealership.  

When P'holz was in regular supply, it was approx' £150-200 for a Plinth Blank from an individual supplying Blanks, and even cheaper if sourced as an off cut through another source.

I would have selected P'holz over the Granite, if I knew what I do now, through the experiences of both in use. 

Today I have selected P'holz for Plinth Purposes, over other owned Board Materials and other Structures available to me as a Plinth Material.

As said Sub Plinths in this material can be found selling at £1000, so sourcing and working with a Board of Densified Wood, if very cost effective.
