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 ?

Hi Geoch – You are always candid, honest and passionate based on your personal experiences/observations. I can appreciate that. We are all big boys here.

But let me be candid and honest too. My personal detailed TT impressions are on my page however just briefly. The VPI TNT was originally designed for the ET2. There are many out there. I owned one for many years and can say that when you say:

Probably because of a faulty air pressure or wrong alignment, or even because the DP80 is a hell of a TT while the TNT was a lousy plastic sucker.

I would put my money personally on a faulty pump and the wrong alignment part. You now have me wondering if Nikola considers his big Kuzma to be a big plastic sucker?

My old TNT modified with thread, became a new TT far surpassing the belt version in my own setup. The TNT/ET2 you heard if it was an early TNT version with a basic ET2/pump and the POS PLC controller as mine was originally – well I rate it “2 out of 10” compared to the threaded TNT/SDS version with ET2 HP arm and pump mods later. In thread form it surpassed my SP10 mkII set up and forced me to look for the next version. But it became a little higher maintenance in this form. Just like that special girlfriend. I remember our discussion on what material I should use to fill the leg cavities as I was resting them on the excellent AT 616 pneumatic footers instead of the sprung feet.

Your reply back to me was to used beeswax and leadshot in the cavity. Ingenious I thought at the time but it would be really messy. I ended up filling all four of them with blue tac at one point. But it produced a sound like it was coming from the dead. Unlike death itself this was easily reversible. So we have our personal experiences. The Verdier btw took this little tonearm to unimaginable heights for me personally. The JN Lenco however I am keeping safe for when I have more time to explore it properly.

“I'm not convinced for the maturity of what the industry has to offer on this subject as yet and the clinical environmental conditions of handling them regarding dust or smoking is another disturbing thing to consider.”

You are absolutely right. IMO - The demand for these tonearms has come from what I can tell from word of mouth and forums such as this. Just look at the upgrades discussed on this forum alone. Many here now have turnkey systems. One button turns everything on. When people buy these ET2 tonearms used they do not realize that the price being paid is not the price of admission. Significant investment and more importantly time needs to be made in a proper pump system. A new ET 2.5 is not cheap, and then the pump is not included. Bruce Thigpen makes it clear on his website, that sourcing of the pump system is not included but they will offer advice and help to source one. For someone inquiring into a ET2.5 and maybe getting to the next step of ownership – this is not appealing. But there are so many pump options available with it that Bruce has no choice but to leave this option open. Unfortunately most into analog want plug and play I have found and are not willing to do their homework here.
Cheers
Dg, I use 1.5 meters of wire with no sign of any issue due to length. I suppose it's possible that a shorter length sounds even better, but the Cardas and Discovery looms are both 1.0 m and the AN is obviously superior to both; according to my tastes, of course.
Hey guys, I've mounted my Acutex 420 and thought I'd send some intial impressions. I am having a couple issues with my current wire loom that's keeping me from an optimal set-up. So please keep this in mind regarding remarks I make on cartridge performance.
My wire loom was made with longer than usual cartridge clips that require me to use an 1/8" spacer. Now that the cartridge total height has increased, I've had to make adjustments to allow for this by raising the manifold assembly in the vertical post. Only now can I get the top of cartridge body parallel to the record surface with the arc block centered in it's adjustment range. So, now the center of the spindle is farther than I'd like above the height of an lp.
The tonearm exits the back of the armwand: I constructed this with a braid/shield inside the armwand and had it exit around an 1" . This makes it impossible to get overhang exactly right with this cartridge at this point. I'm about 1/32" too far forward.
Obviously, I will correct these issues in the future.
I'm using a double leaf spring, w/ VTF @ 1.5 grams, top fo cart. body parallel with lp, running slightly above 17 psi. All remarks are comparing the just removed Dyna D3.
The first thing that hits me is the bass. It has greater authority, the bass lines are very easy to follow, has greater realism.
The midrange is natural and unforced. The treble is pleasant and has no edge. Not as extended as the Dyna.
Soundstage has nice separation, placement of performers and instuments are nice in the context of the total picture.The spread isn't as wide as the Dyna. The Dyna has more of an airly quality. Soundstage doesn't extend beyond speakers.
Doesn't do audio gymnastics, but that's is fine with me.
I'm loving it already and do not miss the Dyna.
The two lps I've listened to so far are Police "Ghost in the Machine" which was the last lp I heard befor making the switch and Shawn Colvin "Steady On". If you don't already own the latter, I can recommend it.

Bear in mind that you are not comparing a Dynavector 17D to an Acutex 420.
You are comparing a "Dynavector 17D plus Bob's Cinemag 3440 MC transformer" to an Acutex 420.
Hi Slaw, tuneful bass indeed. The Acutex on the ET makes the most realistic bass that I have ever gotten with my setup. Not just powerful (a lot of cartridges do that), the bass moves with the same rhythmic impetus as the rest of the frequency range; essential for music to "make sense". A truism among musicians is that things always start from the bottom up. Again, not the quantity of bass, but the clarity of the musical contribution of the bass "voices". Get that right, and a lot of things fall into place.

The soundstage will open up as the cartridge settles. When you say you have the "body" paralell to the LP, I hope you mean the top mounting plate and not the "nose" of the cartridge. After the cartridge settles in (takes quite a while) try increasing VTF .1-.3 grams, while at the same time raising the back of the ET a bit. Increasing the tracking force will lower VTA.

Also check the amount of torque used on all the ET adjustment bolts. A subtle effect, but I have found that if the bolts are too tight the sound is not as open and opulent as it can be. It's even easy to over tighten the bolt that secures the end cap that holds the leaf spring to the extent that the spindle tube can be squeezed and become misshapen, adversely affecting the sound.
