Eminent Technology ET-2 Tonearm Owners



Where are you? What mods have you done ?

I have been using these ET2's for over 9 years now.
I am still figuring them out and learning from them. They can be modified in so many ways. Bruce Thigpen laid down the GENIUS behind this tonearm over 20 years ago. Some of you have owned them for over 20 years !

Tell us your secrets.

New owners – what questions do you have ?

We may even be able to coax Bruce to post here. :^)

There are so many modifications that can be done.

Dressing of the wire with this arm is critical to get optimum sonics along with proper counterweight setup.

Let me start it off.

Please tell us what you have found to be the best wire for the ET-2 tonearm ? One that is pliable/doesn’t crink or curl. Whats the best way of dressing it so it doesn’t impact the arm. Through the spindle - Over the manifold - Below manifold ? What have you come up with ?

I want to say one other thing related to the discussion I kind of created recently. Music. This is what it's all about. Whether you're in it for the mechanics or the feeling...... that's what we all have to decide.

If I was asked, what I could do without, my electronics(system) or my lps, that's easy............ take my electronics, PLEASE!

My heart @ soul is in the music , $@^$## the electronics!!!

By the way, did you hear about the guy who went record shopping @..................

Slaw - My heart @ soul is in the music , $@^$## the electronics.

I agree - I want to share something I came across today.

Check out what the lead track is.

Groove Into Bits Vol. 1 - Tracklist:

1. Steady on - Shawn Colvin
2. Last days at the lodge - Amos Lee
3. Saltarello - Dead Can Dance
4. Golden Brown - The Strangles
5. Come to the river - Hans Theesink & Terry Evans
6. Blues Walk - Lou Donaldson

My favourite songs on side one of Shawn Colvin are actually shotgun down the avalanche and stranded.
Super LP thanks for the recommendation

FWIW - I have a room I play with the gear in; it is a form of therapy for me so it really is beneficial, and l learn a lot in there. This doesn’t have to be a big or elaborate room.
I have the other room that rarely changes. LPs’s all over the place from previous listening sessions, along with some tape. I really enjoy music in there to get my fix and learn a lot about the music itself in there. If something happens in the first room that I think might be good to introduce into the second room. I go for it.
Well, per Bruce T's recommendation, I installed one of my two original (lower mass) aluminum arm wands in place of the magnesium wand (lighter version) that I have been using since purchasing it about twenty (!) years ago. I had been meaning to try the original wand again since returning to MM cartridges about two years ago, but because of the somewhat difficult arrangement that I have of a continuous run of tonearm wire from cartridge clips to preamplifier, I had not gotten around to it. Also keep in mind that I had wrapped the magnesium wand with cloth tape for extra damping, but also adding extra mass.

These are very preliminary observations/reactions, but I must say that I am surprised at the magnitude of change in the sound; with the Acutex 420. It is far from being a slam-dunk in favor of the aluminum wand; in spite of BT's assertion that the aluminum wand would work better with the high-compliance Acutex. The reduction in bass weight with the aluminum wand is striking, with an apparent increase in clarity that I am not yet convinced is not simply a psychoacoustic effect due to the reduction in bass weight and overall fullness. Somewhat paradoxically, the overall sound is leaner while seeming to have less grain in the highs. I need to spend more time with this wand to really understand what is going on, but after only a few sides it has become even more clear that this cartridge, aside from the already and often discussed sensitivity to VTA, VTF, azimuth, etc., may also be unusually sensitive to arm (headshell?) mass in unexpected ways; which may explain, at least in part, the different reactions to this cartridge.

More to follow.
Frogman -
I got considerably more transparency and even less grain when I removed the inner foam and stripped off the heatshrink from the aluminium arm tube with both low compliance ( Denon 103 Garrott ) and high compliance ( Shure V15VMR ) cartridges.
Also I suggested implementing electromagnetic dampening of lateral movement by using fridge magnets early in this post - disappointingly for me, only ct0517 has tried it - a $5 tweak that stabilises the cartridges so much, you get increased output and have to turn the volume down. The dampening increases proportionally with lateral arm movement speed.
By the way magnesium has a lower Youngs Modulus than aluminium, which means it is much softer and less rigid ceteris parabus.
If you want to go one step further, you can open up the cartridge end of the wand ( the aluminium is very thin ), pull out the soft teflon insert, and replace it with a piece of carbon fiber. You can use superglue and clamp it up with a decent vice. This gives you a much stiffer headshell.
Dear Dover, great stuff! Thank you.

I will definitely try removing the heat shrink and the Teflon insert. When I first got the magnesium wand, if memory serves, I was using a Spectral MCR which benefited from the extra mass and dampening of the magnesium wand; with the aluminum wand it was lean and white to the point of being unpleasant sounding in spite of it's tremendous detail retrieval and speed (Raul?). I did not try your magnet dampening tweak as I use the damping trough with my ET2 and lateral movement is already well controlled; I am intrigued however and will try it.

Thanks again, and I will report back after I live with the aluminum wand a little longer.
