Suspensions on turntable...really effective?

diamondears - Suspensions on turntable.......really effective ?

I think that the OP - diamondears is thinking about what type of shoes the turntable is wearing ? Women have this thing for shoes you know. But truth be told I think I do too. My SP10 MKII has worn maybe 15 sets of shoes during past bouts with audiophilia. Each set of 3 shoes transformed its’ personality each time. Yes, turntables have three legs. Well, they only need three legs. We have all heard the term "clothes make a man". How about shoes make a TT ?

But we know that magnetic fields are bad for the sound especially in proximity to low level signals. For that reason I’m out.

Oh no....

Every low level signal phono cartridge consists of key components: the stylus, cantilever, MAGNETS, coils and body. What are we going to now GK......you better go tell every cartridge maker about this.

Now the platter itself on my La Platine is this big aluminum thing, and I think it isolates pretty good as it allows me to use a direct shot of unshielded phono wire.

Geoffkait Of course the other objection is the very slippery nature of the opposing magnets doing the levitating.

Well, I can tell you that La Platine is anything but slippery. In fact the opposing magnets provide braking action to deal with the records behavior, at the record location. Do any others do this ? Kinda cool. The distant motor happily provides pulses of power through loosely applied thread. It can be plucked while the record is playing, and so far no listening can tell I am doing it.
This is really fun to do with Audiophiles that are used to "loading" up the record, "loading" down with heavy clamped center weight and heavy peripheral weight; ready now, activate speed controller, ready, ok. push start ........at speed in milliseconds ......

La Platine - very much like a little girl pushing 6 - 200 lb guys on a playground merry go round.
hey its a unique experience - not for everybody.

Audiophiles are immediately attracted to La Platine because all the family jewels are exposed, accessible, and they think..oh my .. so much to access and modify here.
The problem is ...from what I have heard .....true audiophiles all end up doing the same thing with her... they mess too much with the design...they go to far, and they then get bored because they have destroyed its genius dna, and created "audiophile bedlam".

You heard it here first.

What I’m looking for is some white paper or really comprehensive post or thread discussing the merits (and demerits) of suspensions on turntables.

Hi diamondears

imo - You will always get only one view, opinion when reviewing white papers.

A recommendation, I did this myself and it worked for me. Talk directly with the TT manufacturers whether you own their table or not. They will send you the information you are looking for. You will discover the levels of study and analysis that they went to.

A TT itself is a Sum of its parts - imo

I like this definition from the internet.

A concept in holism. Related to the idea that the total effectiveness of a group of things each interacting with one another is different or greater than their effectiveness when acting in isolation from one another.

It conveys the meaning to me that you can not just look at one aspect of something - especially in this case where we are dealing with vibrations, resonances. Too many audiophiles, including myself can get buried too deep. Go too far down the rabbit hole.


fwiw
I had many conversations with JC Verdier prior to and after my purchase of La Platine Granito Vintage thread model. It has pneumatic shoes and a granito plinth.

JC Verdier

"Granito is a material composed by little pieces of marble of very different origin agglomerated inside a mold with cement. Machined and polished. The resonance of the plinth with its suspension is about 5Hz and it is well absorbed by the air cavities."

some pics of it here.

diamondears - Re magnets, when the magnet moves, so does what’s on top of it?

Not sure I follow what you mean here. Are you referring to my previous post on La Platine ?
On La Platine, the bottom magnet is part of the plinth. The top magnet is part of the platter. There are many pictures showing both ends at this link.
Just scroll down the page.

It can be plucked while the record is playing, and so far no listening can tell I am doing it.

lol
Sorry for the error and the others in my previous post.

That’s it... out with these new Arabica beans my wife bought me - in again with the Costco Zavida. The Arabica brand aren’t kicking in fast enough.

correction to the previous post.

It can be plucked while the record is playing, and so far no "one" listening can tell I am doing it.

@Geoffkait and all manufacturers, designers, dealers, distributors, and all those in the audio business...... posting on Audiogon.

Why don’t you guys take the opportunity to show your company name in your monikers box so all like myself, non professionals, can see your professional affiliation?

Just sayin...

Kudos to those like PBN Audio who have already taken this opportunity.

You said, "Gases are compressible, too." I Never said they weren’t. Sheesh! Never said air is not a gas, either.
Furthermore, I said air is a fluid, not a liquid. Hel-looo!
Obviously liquids are not compressible, at least not generally speaking.

google is my friend.

A fluid is any substance in which the molecules are free to flow. This includes both gases and liquids.
A liquid is any substance in which molecules are free to flow, and volume is fixed or nearly fixed. Liquids are a subset of fluids.

Hmm
Could this be the reason that Lewm’s "small cans of Mandarin Orange slices in water (sealed, of course) footers" work so well for him and his turntables ? - quote taken from TT for life thread.

Now I think that Lewm uses OTL amplifiers ?
When I was using a couple big OTL monoblocks the temperature in the room would rise - quickly.

So Lewm a question for you out of curiosity.

Are your TT’s (and the footers containing water) in the same room as the amplifiers; and if so have you listened to your rig at say 65 degrees F and at 75 degrees F ? Be interested in any differences you found.

They say sound travels faster in warmer air, but that sound travels farther in colder air. And I know I have read that cartridge designers test out their cartridges at a specific temp and humidity level.
If I am dropping big dollars on a cartridge I would be seeking out this info from the designer.

As posted earlier this really is all about the sum of all the parts - including the room and music listener too.

Thx diamondears for letting me ramble. Took my mind off of markets, our dollar..for a bit anyway.

btw- an Audiogon search on those two tables in your last post produced many forum entries of info.

Happy Listening
