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

@dullgrin Thank You for a very fair assessment and your encouragement.

@dogberry Both Natural and Manufactured Stone has been regularly seen in use as a Plinth Material for too many years, the Trend I recollect commenced in the 90's with the Garrard 401 being championed in a Company called Slate Audio's Slate Plinth. The Trend grew to other Decks and even Speaker Cabinets.

Not all can successfully Market Slate, hence new Natural Stone was becoming more mainstream, I chose Granite as my material, as I preferred the demonstrations of Granite on a 401, to those I had been to when Slate was demonstrated.

Being brutally honest, I may have even been more attracted to Granite as I preferred the individuals that were advocates of it for the purpose as a Plinth.

Within my HiFi Group, one member has a paraphernalia of ideas, why Slate is inferior to Granite as a Material to be used within HiFi.

I am not without Granite, I utilise it in plenty of places within my System, but mainly now as one of the materials used in an assembly of various Materials that functions as a Structure.

I am also an owner of Manufactured Stone as a Plinth, which has the Brand Name Corian. Again, this is another material I have chosen not to use as a regular choice, it is pretty much reserved for demonstration purposes.

My Friend who has recently converted to Densified Wood - Panzerholz, has a quantity of Corian in Slabs, as the P'holz has been capable of persuading them to rethink their previous thoughts on Plinth Materials, they are remaining curious, and are in the process of utilising the Corian, to try this material out as a comparison.

Lucky for me I will be able to hear this in use, on a TT and Tonearm of the same design I own. This will allow for Two Set Ups to be used of the same equipment mounted on two different Plinth Materials, additionally this will also allow me to have my Cart' used during a demonstration along with the Two standard Ortofon K'bs available.

If all seems worthwhile, I do believe the Kaneta Designs will be produced in both materials, to take the investigations further.

@dogberry In relation to your notification of your next venture to have a Standalone Tonearm Pod Produced, to be used with the SME 10 and SME M2-9 Tonearms.

I have no doubt the Headshell Design used on the M2-9 is a much-improved mechanical interface over any Products it Superseded from SME.

It does not matter one iota, who is pleased, you are the end listener, and you are the one making choices for how monies are used that leave your account.

I am sure you are to share in many hours of fun filled investigation when these arrive at your home. I sincerely hope there will certainly be a room full of music on a regular occasion. 

If it is off interest, the answer does not have to be immediate. I can donate to you, to assist with having an extension of the experience of a Tonearm Pod, a piece of Densified Wood - Permali that is a 75mm (3 inch ) Thick Material, cut to a dimension that would suit having a Standalone Tonearm Pod produced from it.

Let me know, there is no rush.

Very kind of you, John, but I shall decline. My two turntables sit atop a very heavy 17th century oak chest, which I have carefully levelled. I don't think a slab of anything, however good it is in the audio realm, will be acceptable to SWMBO.

I started out just trying to find a cartridge I could live with when my London Reference is finally done, and I ended up with a handful of rather nice carts and a second turntable! And now the madness proceeds towards four tonearms...

@dogberry It is not madness to have a plan in mind for Four Tonearms, it is a little unusual to have four in use consecutively, but definitely not unusual to own Four Tonearms and a selection of usable Cart's to match that number or more even. 

I have owned and used approx' Nine Tonearms to get to the place I am today with a Tonearm.

Today with only one Tonearm in use, I still have a selection of Seven retained, along with LOMC, HOMC and MM Cart's, all with a usable number of hours left on a Stylus. I don't know how ageism may be affecting some through the time in storage.  

As for the offer for the Permali, the offer is for a piece of the size that would be able to be turned into a Tonearm Pod, that by design, when finished will be able to be stored in a cupboard when not in use, or only be as intrusive as a Black Brass, if kept in use. 

A Slab to not be accepted by SWMBO will be very expensive to send onto you.

I was given my own room without any dispute for the HiFi, it was like an approval to go off the scale with madness. To get the idea, the Power Amps are seated on a 250Kg slab of Granite. In the Room I would refer to that one as adventurous.

There are more quirks to be found. 

I am also an owner of Manufactured Stone as a Plinth, which has the Brand Name Corian. 

Corian is about 1/3 resin 2/3 mineral.

Engineered quartz stone is 95% quartz  / 5% resin.

These materials are quite different. I would never describe corian as a manufactured stone.
