A Copernican View of the Turntable System

T_bone,

I have been trying my stand alone armbase for the past three days and it has not moved, despite my having been deliberately more robust in handling than I would normally. Unlike Halcro, my armbase (as can be seen on my System page) is only held in place with a few blobs of blue tac. I did take some time in adjusting to ensure that arm and cartridge were perfectly aligned with the detached nude TT but after that I have treated the entire exercise as if it was a normally fixed arrangement. As you know, I'm using the AT616 pneumatic footers and so that might be encouraging if the results althmore surprising for that.

It is too early to be certain of all my findings but I would honestly (and VERY unexpectedly) say that you should just give it a go. The differences are blatant, to me.

Whilst the thread is not on the front page of the Analogue Forum, if you go to the Recent Discourse Forums and press 12 hour, 24 hour or 48 hour link, you will find it there.

I like going this way as a routine b cause you get to see all the current discourse and in their order of popular activity.

However I have asked Audiogon the reason for this?

Dear Chris /all: The " naked TT project " is similar as what happen with the MM/MI alternative: many people are trying/testing with no posts in the threads.

Both alternatives are so un-expensive and so easy to achieve that IMHO it is an audio " waste/lose " not to try it, at least just to " cover up a hole in our audio culture ".

Btw, Banquo363: from the AT operation manual the AT616 works between 10-60kgs. It works for me and for Dgob too.

Now, each 616 footer is a set of three internal and independent insulators design where the third one works when the item weight is over 30kg.

Regards and enjoy the music,
Raul.

We're baaack.....

I re-assured the moderators that I really didn't take my pet snake for a regular walk..........it's just a special treat.

Halcro, points are a sort of mechanical one-way diode. That is they are fairly efficient at transmitting vibration in only one direction. So if your points are pointed *down* under your tone arm: welcome to your plinth, the anti-vibration platform.

Any good anti-vibration platform will have both 'acoustically dead' and 'absolutely rigid' as a mantra.

I agree that a bad plinth is likely worse than none. I've been down this path before- my turntable has been in development since the early 1990s. So the comments I've been making are based out of experience, not conjecture.

If you want to separate something, and if the 'table is not a direct-drive, then the motor might be a better candidate. However IME the vibration of the motor will be of no significance if the plinth works right.
