Turntables: 2 Tonearms. What do you Have or Know About?

@elliottbnewcombjr I would like to say, I learnt my lesson with Granite Monoliths.

That is a tale I can't tell, I have a 250Kg Granite Lintel/Engineers Plate, used as part of the support structure for the 845 Monoblocks.

The equipment Racks are seated on Steel Plates of a dimension 900 x 700 x 15 (36" x 28" x 5/8") again a Holiday is needed following the experience of being put in place.

I am hoping my 'new kid on the block' - 'go to' material, is a worthy substitute for these when I return to using the system.

OVERKILL: (websters): ’Found under the equipment rack’

My final TT support, to deal with my springy floors, drop the needle, "gimme 2 steps..."

Notice, my TT’s oversized plinth is on a deeper glass top I had made, it cantilevers a few inches over the back of the normal depth ’glass topped’ racks below.

Fortunately the Spinner’s weight is forward, so luckily no rear support under the back edge of the glass was needed. I designed and built the racks below it, 3 heights

They can surround equipment with some heat, they are ventilated, wide open in the back, see my tube preamp below my tube amp.

anyway, hard not to digress, but to note, many TT’s that take multiple arms need more space, depth, or width, like my friend’s Luxman PD444

My OEM dust cover is lift off, Luxman's is hinged

Fortunately for myself I have not gone to great expense for my equipment support.

Much of the materials in use are selected from trialing and elimination of materials.

When a Material is discovered that has a impact on the sonic that is desirable to myself, I will then attempt over time to discover the same material type in different dimensions and assess the impact it has.

Granite used as Tier in a Support Structure, certainly does offer something quite special for my needs when used in a Mass, not usually considered to be used.

Even a Tier used on my support plinths for a Cabinet Speaker has shown to be much more beneficial when it is a substantially increased thickness used over the earlier samples of 20mm-40mm. Extra Thick Granite used in such a position is still a little user friendly, it is the Speakers Weight that 'hurts good'.

a DUST COVER, yay!
