Eminent Technology ET-2 Tonearm Owners

@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.

@slaw: Regarding Mapleshade scale - as much as I like it's precision, it is always drifting slightly (besides the necessity to place the needle at exactly the same spot).Thinking about it, I dream about a solid 5kg linear low noise power supply to feed the scale and to be placed on the subchassis while measuring :-)

@pegasus ,

I made a mark on it’s center resting plate for my own peace of mind..

Check out the Rega at the Cable Co website... I think you’ll be impressed! It seems that everything about a scales' construction/accuracy has been rethought and addressed.
