Eminent Technology ET-2 Tonearm Owners

Not sure if your last post was intended for me or not, Slaw.  In the event it wasn’t or you still want company:

Well, work being what it is for me this time of year and some relatively expected life/family issues, I’ve had practically no time to “play” with my system, so the two (single and double spring) long I-beams that I received from Bruce are still sitting unused and lonely.  My impressions of my home-brew I-beam from a few years back may not be entirely relevant for obvious reasons, but the use of blu-tack should work the same way on the “official” beams.  I will certainly respond when I can do some critical listening using them.

Yes, I know this is an ET II forum but I can't restrain my recent good fortune.  A family member just gave me a Garrard 301 for my birthday.  It is complete with a Garrard arm.  As much as I love my VPI HW 19 (which I will keep and become a two turntable kind'a guy), this is a turntable I have lusted after for nearly 40 years.  Since it comes to me at no cost I can spend some $$ on an arm.  I know that while Chris is reluctant to admit it, he does have some pivoted arms.  Do y'all have any recommendations for an arm for this table.  The plinth is not an issue as I will be replacing the original Garrard plinth.  Perhaps with a new plinth it would even accommodate an ET II, but I'd like to hear your opinions.

NOSTALGIA

Many years ago there was a high end store in Soutn Dade county, Florida run by a very eccentric owner (I think his name was Larry).  He had a 301 mounted in (believe it or not) a huge butcher block.  One of those that is a freestanding table that sits in the middle of your kitchen.  Not sure what arm he was running, but it was S shaped - probably an SME.  I have no recollection of the cartridge he was using but I have a long standing recollection that, at the time (40 years ago), it was the best sounding vinyl I had ever heard.

@frogman,

It wasn’t directed at you or anyone.

I look forward to your impressions.

@vpi,

I don’t have any specific recommendations for you. I assume the S-shaped arms are shaped this way to provide more mass that would have complimented the majority of cartridges of that era? I’m envious!

- Regarding I-beam and weights: I often used BluTak to adjust or increase the counterweight mass to a certain degree and never felt it was compromising the sound in any way. I also form tiny balls of ca. 0.05g (or less) to precisely adjust the VTF in a repeatable way (by putting on and taking them away). For this I measure these balls on a 0.01 precise Mapleshade scale. BluTak is simple & very practical.

- On the website of the Adanalog MG1 arm – which is similar to the ET2 – several of the user images show Lenco drives with new plinths, and I heard very good sounds from a Lenco / Reinders PTP / limestone plinth with an MG1 arm.
In my experience idler wheel or direct drives work very very good for air bearing arms, ie. optimal. (Better in my system than a very good Merrill Heirloom, a medium weight belt / subchassis ET 2 combo).
- I think this has to do with the tendency of a belted subchassis to slightly  (counter-) rotate around the platter axis at low subsonic frequencies and the way this continually decenters the air bearing a bit, compromising (to a certain degree) bass quality and others. The very low horizontal resonance of air bearing arms adds to that effect.
A radial arm has the center of its horizontal mass (almost) in the rigidly placed bearing and so the cartridge/arm combo is not displaced by horizontal accelaration (or much, much less).

@pegasus ,

Your post reminds me of some of the possible adverse affects of a suspended (spring especially) plinth TT used in conjunction with the ET. I believe this was THE major pitfall I encountered through all of my iterations of the HW-19 and all of the upgrades I did to it and my ultimately going in another direction for a while. I do not regret my learning experience one bit.

(In your last post, I noticed you referred to the Mapleshade scale. I’ve used it for years).

I do admit that after watching MF’s Rega factory tour several months back, one (of the many things) that struck me was their development of an extremely accurate scale! I’ve been waiting for it to come to market. Finally, It’s here! I have one on it’s way to me now.
