Eminent Technology ET-2 Tonearm Owners

Chris: I am referring to 'plinth' as does VPI when describing their tt designs, and as far as I know, most TT manufacturerers do. I have to say, the wiki link you provided seems to confirm the intent I initially meant. The plinth in my TT is 'the' platform you speak of. The armboard is connected to this 'plinth', (and becomes part of it) that supports the platter and bearing.

Chris: I think I oversimplified my response to this now, I appologize.

Dgarretson: I looked again at your "egg beater" wire loom. Very interesting and "smart" execution. Question, Do the two 'outer strands' of your egg beater design, need to be slightly longer to acheive proper "force vector"? If so, does this have an effect on your balanced cable design?

Here is some food for thought.

I have found when comparing and listening to how the vibrations and resonances in this hobby affect the different sounds we get; that identifying “ground zero” aka the common base/plinth for all components in a turntable system (bearing/platter/spindle/motor/tonearm-cartridge) was important for me.

Slaw – in your system pic - your motor/enclosure is not attached, or even on the same base as your VPI plinth - what this means to me ...

Your VPI plinth is the plinth/base for only the platter/spindle/bearing and tonearm/cartridge.
Your wall shelf is the plinth/base for the actual motor.
Being a vibration/resonance hobby everything has an effect on your overall sound that we are getting so ….

What is the overall turntable “system” common base/plinth that the overall sound is actually based on ?

IMO

1) If all of your turntable parts were on one wall shelf your actual overall turntable system plinth would be that shelf.
2) If all of it was on two separate wall shelves then “The Wall” itself becomes the common base/plinth.
3) Still further based on your photo – if the motor is on the wall shelf and the remaining turntable parts on a floor rack - as it appears in your photo? , then both wall and floor factor in as a shared base/plinth for the turntable system, and how resonances and vibrations will affect the sound.

Thoughts ?

No more coffee for me this morning ...

Interesting Chris....as I have also found the 420STR to act much like a LOMC on my Victor DD in its susceptibility to 'feedback' when the volume is turned up?
This despite the fact that the phono stage gain is set to the low MM value which, incidentally displays no such 'feedback' with 'normal' MMs?

Do you have any thoughts on why this should be the case with the 420STR?

From the nude thread

Perhaps the fact that the 420STR is like a giant antenna (according to Chris and the Professor Timeltel).

Hi Henry – I gave this some more thought. I prefer to label the 420str as a “Nude” cartridge – I thought u would like this name? The 420str has very little “clothing” so why not call it nude. Its not damped and protected to the nine’s like other cartridges so it needs an arm that can pass thru or eliminate resonances really well. If you have any issues with your turntable setup, it will tell you like no other cartridge so far for me. This can be good or bad depending on your perspective.

On a belt or thread drive TT where there is excellent motor isolation, this cartridge has had no issues for me whatsoever. It did however require me to lock things down better on the idler and dd tables, thus its value to me for more than just the sound, but as a test cartridge. I believe that most of the favorable impressions of the 420str here, were with belt / thread drive users ?
Is this not so ?

I look forward to your impressions of it Henry - on your Belt drive Raven when u get your phono stage up and running.

As an update the 420str arrived safely and is with BT.

Slaw – I found a Shawn Colvin - Steady On - LP. :^)

Dear Chris, One may think 'one thread is not the other'
but I got not only 'philosophycal' but also psychological
(involving Freud) disagreement with Lew in the 'nude turntable project'. He persisted in his claim that 'plinth=base' because of the English dictionary (aka
synonym). I as a foreigner was obviously not aware of this 'fact'. That is to say that 'plinth' means the same as 'base'. Aka 'identity relationship' between meanings(??) However he also postulated 'the qualitative difference between a real plinth ' and those 'illegitimate footers'. But because my 'philosophical' opinion is that the meaning of
words depend on the context in which thy are used I mentioned my legs as footers and postulated the opposite. That they are an 'legitimate' base for my nacked or dressed body. However I also mentioned the possibility that in some future time I may need a 'plinth' like an wheel-chair. This I would think will mean some 'qualitative difference' with the previous state of affair but in the opposite 'direction' than assumed by Lew. This interesting (?) discussion was alas ended because of the irritation by some other member: no philosophycal BS in public please ; mail each other if you need.
Regards,
