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 Dover – thx for the info. Please tell me there is not going to be a pop test quiz on that material.

More on resonances

My Verdier plinth – which holds the platter, armpod, spindle (no physical bearing) instead two large shielded magnets - is made of Granito.

Granito is a material composed by little pieces of marble of very different origin agglomerated inside a mold with cement. Machined and polished.

The resonance of the plinth with its suspension is about 5Hz and it is well absorbed by the air cavities.

The Granito and resonance info comes from Mr.Verdier himself to me in an email.

My SP10 unit (version 4) is bolted in by four - one inch solid stainless columns to an MDF plinth which in turn sits on a pneumatic suspension, which in turn is on a wall shelf (load bearing) The MDF base is a full TT system plinth as it holds all the goods. It supposedly resonates a little lower than slate. The armpod 19 lbs relies on its weight alone but my version 5 plans are to have it bolted in as well, and I am not sure what material the next plinth will be.

The Nantais L75 is an all wood layered plinth and I have convinced myself that if I take my boat to the middle of Lake Ontario and drop it over it will sink. It feels like cement when carried.

This has been said before – The ET2.5 spindle resonates at 2-3 Hz. The skinnier ET 2.0 spindle resonates at around 5-6 hz.

Resonances can be fun ?
Nandric: I took the plunge and ordered the Clearaudio. On Take Five Audio's site, they looked to be short enough to work well. Thanks for the tip for EBay.UK, which is where I ordered.
Hi Slaw, They are 6x2 mm and made from beryllium/copper.
The shrink is 13 mm and can be cut of course. If you need
less expensive 'tags' for experiments there are also Michell Engineering 'solid brass /silver plated ' which look like Clearaudio and cost 12,50 GBP.

I liked the pic you provided us of the wire Take Five Audio built for you. I loved the attention that was paid to the gradual step down coming out of the WBTs. Was this accomplished with teflon tubing?

Slaw - I just got Gene's answer

I am quoting.

"For those WBT RCA's the buildup was done with several layers of shrinktube. The first piece is 1/16" CPX 100 Black, you have to be EXTREMELY careful when applying heat so that you do not fuse the insulation together on the wires. From there it is built up using 1/4" and 3/8" CPA type shrinktube with the last piece covering the first two for an overall clean stepped appearance."

here's the pic again - I am not affiliated with Take Five - Just a customer.

Thanks guys! I am not confident at all when it comes to soldering these little tonearm wires to heavier gauge clips. I just received my AN wire... boy is it skinny! The great part about it is, it is extremely flexible, which will ultimately be a plus with an ET wireloom. I have at least 3 projects ahead of me, all having to do with the ET.

Chris: My post regarding the aluminum plate supplied w/ the ET was just to hopefully get anyone's experience w/or w/o the plate on a VPI acrylic armboard. My concern being that the acrylic may be too soft or not, to be used w/o the plate, and how each may have sounded. I have, as an upcoming project, a DIY armboard, so I'll most likely eliminate the plate as I'll be using a harder substance as the interface. That's my plan and I'm sticking to it, (for now) lol.

Any tips on soldering will be very much appreciated. I'm usually more likely to take my sweet time getting mentally prepared.
