A Copernican View of the Turntable System

Not to bad Unoear. I am curious to hear about your experiences. I am in contact with Minus-K for a long time but we failed coming together because of the weight problem - 250 pds. It seems they now have solved the issue. Let's see.

Dear Halcro,
maybe the weak side of the Continuums are their isolation issues. Neither the magnetive leverage of the Caliburn nor the feet of the Criterion are benchmark solutions. Therefore I had to implement my own isolation.

For all my TTs I have special isolation solutions, not only the stands but also additional special platforms (HRS, Micro-Seiki Air, Copulare Corals) provide a vey stable, balanced and quiet environment. It took quite some efforts to find appropriate measurements. But believe me it is worth a try, also to separate motors, body and tonearm stands.

Hi Thuchan,

Yes, my weight requirements for the Minus-K platforms were not as demanding as your needs. I only required 100 lb. and 125 lb. platforms for my tables; however, I do see where they do have a 250 lb. solution now available in their platform mix. Good luck in working out a fix for your isolation requirements, I am sure that you will find what you are looking for... I will post my observations when it all constellates in November.

BTW, thank you for your direct and indirect help kicking me off on this new adventure...indirectly when I run into spousal resistance, I always quietly show her the extent of your growing audio virus :-).

Hi Syntax,

I do enjoy your tall sense of humor :-)!

Yes, bandwidth is always a consideration in obtaining great design and implantation!

Thanks again for your kind encouragement regarding maximizing the reduction of distortions along the signal path of the audio chain.

Halcro,

Whilst I do not like sprung turntables I agree with Dertonam you cant write them off. The key mistake most suspended tt's with belt drive have is that they have the motor drive on a different chassis from the suspended plinth on which they mount the platter/bearing/arm. If the motor is mounted on the floating plinth along with the arm/platter then it is possible to get speed stability - ie rigid coupling of the motor/platter/arm/cartridge loop is the key.
For isolation my non suspended high mass turntable is mounted on a wall hung shelf which lowered the noise floor and cleaned up the bottom end considerably over floor racks with various isolation devices. My floor is a sprung wooden floor, so you may not get that difference with a concrete floor.
