A Copernican View of the Turntable System

Dear Nikola – you said.

I 'assist' ( by looking) my machinist while
he was busy to cut from a billet of bronze a collar for my
Pioneer P-70 tonearm.

For your information – here in North America machine shop rates are by the hour and are based on the following criteria.

$ XX – tell him what you want and go away – come back to pick it up.

$ XXX – if you want to watch him make it

$ XXXX – if you want to watch him and also ask questions.

Now I know at least a couple of us have spare sp10 mkII’s sitting idle ? Well my 2nd sp10 mkII recently got set up in the city. I am satisfied with the sound but being this a hobby I need to get more height on the footers to accommodate another armpod that I am planning on making.

Now I naively thought that all Australians were as nice as Henry. How greedy that person is on ebay asking what he is for those AT 616’s.

This got me thinking. I believe I had a mini epiphany. I was so pumped about it and its simplicity that I had to head over to the local machine shop to see if the costs were in line. The costs were so I had some made. Attached is a picture of them.

These are 5 inches high and made from One Inch diameter solid stainless steel and have adjustable threads. I have just installed them, may get some time to listen before we go away for the weekend. Any comments from those that have direct experience with Nude Sp10’s ?

Well ok I will open it up to all ? I have a thick layer of Teflon.

I have found that different footers on TT’s change the sound dramatically. Any guesses on how the sound will change from the Pneumatic AT616’s ? They are coupled to 4 inches of solid maple that is isolated on three metallic filled legs spiked to the house basement slab.

Oh I almost forgot – Material and labor $48 cash for all four. I had to go away for a couple of hours and come back to pick them up.

BTW – thank you very much Henry for teaching me how to add links and pictures. What a PITA it is an archaic outdated system.

Cheers

Dear Chris, You made some kind of drilling (oil) platform
for your SP-10. Looks to me more convincing than the AT footers below the cover because this cover is very questionable as support. I would add the Stillpoints underneath the the steel 'points' for some damping. I assume that the threads are made in the SP-10 frame? This way you don't need the AT 616 and than (as seller)will probable have some other perspective reg. other Australians than Henry.

Regards,

Dear Lew, You must feel 'Majestic' at present. The
rumours even in Holland are that you now own the best speakers in the world; anyway the best electrostatics ever.
Then you have your both sons near you so you must be a very happy guy at the moment. Hope your sons also love jazz.

Regards,

Hi Ct0517,

I tried to send this before but it seemed to fail. If I therefore repeat my self here I can only apologize.

My experience with the AT616's beneath a nude Technics SP10 Mk2 found improved performance, particularly in the areas of timbre and detail retrieval. This means that you will more clearly be able to distinguish instruments (such as a viola and violin and a wider range of percussive instruments). It also means that the retrieval of inner detail with instruments such as various guitars, double bass and piano are much improved.

My earlier experience with the nude Technics included using Syposium couplers on a Symposium Ultra platform and using a wide variety of footers and cones on distinct platforms. These were all fairly pleasing. However, using the AT616's was a marked improvement on these options.

I hope this helps and good luck

Jcarr,
you forgot something: a ladder !

by placing a ladder (which reaches high enough over the shielding) in front of the TT you will be able to climb onto it and maintain the TT from above.

But seriously: air isolation is one of the best measurements if designed and implemented properly.

I am wondering why most people are positioning their TT(s) near one of the sidewalls of their listening room using very long cables and also giving their speaker systems the opportunity shooting into the room free
and fast. Why not designing a LS system and positioning it two meters in front of the rear wall in such a way that most of the waves are not entering the space one meter behind and in between the speakers. reflections should be dispersed by corner, rear wall and ceiling measurements too.

We are always speaking about one unit - a TT or an arm pod. But we never look at the whole system - the listening room.

best & fun only
