Every day I see another turntable recommendation...

Your example of an earthquake (caused by seismic movements, not by vibrations), is extreme.  Yes an earthquake may spoil your listening.  It may also bring your house down around you.

@rsf507 Thank You for your Input, I am sure the OP will be very pleased with the information as well, I really hope the OP has a opportunity to receive a demonstration of the Brands Models. 

As for me, I am very sure footed in such matters, and when the time is right I will be receiving a demonstration of this Companies products, hopefully with ancillaries of my choice.

@clearthinker  As a Support Structure for my TT's,  I use Mass combined with suspension.

Granite and Steel Plate is my got to material to create Mass.                                    A variety of Materials and Devices are used to create the suspension element.

What has changed today for myself is my methods used for Plinth Materials.

I was at one point a person who was happy to have a Nine and a Half Stone (60Kg) Plinth.

Today that has changed, I am a user of compressed lighter in weight materials, of which I will end up with a Plinth Produced from Densified Wood.

My Material of choice is from the Brand Delignit and the Product is Panzerholz.

I am familiar with this material and have had demonstrations of TT's using it as a Plinth.

A friend who I assisted with sourcing a supply has recently produced a Plinth for their TT and Tonearm, which is the same as my own.

The reports returned are uplifting to say the least, the descriptions used about the noticeable positive improvements are very encouraging, the impact was so encouraging the individual has now allocated a spare piece of Panzerholz as a Sub Plinth, which is a method I have been demonstrating to very good effect at recent local HiFi Group meetings. 

For the OP, and the members with a curiosity or already in possession of the Kuzma Brand. The link is an alternative view of the Kuzma Brand from a trusted source I use, who has been presented on here in the past known as Juergen.

Juergen has a vast experience and is a individual that is a pleasure to read up on their experiences, taking a little onboard of his assessments is a worthwhile undertaking.  

The review is backed up by a suggestion that the revered Turntable designer Hideki Nishikawa who is also responsible for the Tech DAS Brand had been showing an interest and curiosity in the designs used for the Kuzma Models.

That in itself is good reason to have a curiosity about what the Kuzma Brand can create within a system.

It is always best to have access to a broader range of descriptions for any devices that are of interest and can come with a need to spend a fair sum of monies.

I went from a Clearaudio Concept with Hana EH to a Clearaudio Ovation with a Clearaudio Universal tonearm and Hana ML. Worlds different and astonishingly good. Could be my last table, possibly not. What made the upgrade even better was selling my Chinook (which blew away my Musical Surroundings Nova III) moving up to the Allnic H-3000. At the advice of others, the phono really does need to be upgraded. My Allnic is one of my favorites and possibly my last phono I'll need.

Spend the money now or you'll be continuing to spend it. Choice is yours. 

@pindac can I ask where are you located?

@saulh, I confess at the outset that I haven't read through this entire thread. However, as some have suggested, going "all in" on a TT set-up can mean many things. Focusing only on TT, arm & cart is, IMHO, rather myopic. There are definitely other necessary accoutrements for achieving the "best" sonic results possible in whatever budget target you set. Respectfully, I suggest adding a good record cleaning machine or system to your list of usual suspects, in addition to a good phono pre-amp. Clean records (i.e. not only clean-looking but actually clean, down to the grooves) are indispensable to achieving the best sonic fidelity with any good quality equipment you choose. If you want ease & convenience in the record cleaning department, have a look at the Degritter. If you don't mind a more labor-intensive approach, you can achieve the same or better results with a lash-up system at half the cost. Regardless, CLEAN records will be indispensable to great vinyl fidelity.  BTW:  even brand-new records should be cleaned before their first play. There will also be other things you'll need, as well (e.g. record camp or weight; stylus cleaner; LAST record preservative; etc.). Up for a little heavy reading and a hell of an education on the care & feeding of vinyl LP's? Check out "Precision Aqueous Cleaning of Vinyl Records" by Neil Antin on The Vinyl Press. Also, you might want to hang out at Analog Planet for a while and get to know Michael Fremer. All the Best!
