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 ?

Thigpens' recommendations are that with records with an eccentricity of 1/8" a low mass pivoted arm will be superior.

Dover this has been mentioned many times here and is documented in the ET2 manual. What I am curious about however is that at the time of printing of the original ET2 manual MM’s were in their heyday. MC’s became more popular later and BT adjusted with the 2.5. I am wondering if he was printing an update to his manual, if a heavier mass pivot over a lower mass one would be recommended for MC specifically. Any opinion ?

Fwiw

From my record collection there are idk maybe 150 -200 put aside – they can be seen on the ground in the pic of my listening room. These I listen to on a regular basis.
From this group there is only one record I am aware of that falls in that range of 1/8 inch. This record happens to be one of my wife’s favorites and I use it to ....entice her into the room :^)

My solution to this oddball record was to drill out the hole and spend 30 seconds centering it with my DIY center weight seen here.

The pressure points are on the outside and there is a washer underneath. Actually various size washers can be used as needed. Mostly however my records are in good shape warp and off center hole wise (meaning not visually noticeable).

It may do so, but not by design. If not carefully dressed between the gantry and the wand, the tonearm wires have the greater potential to do harm by fouling the wand's free movement. The torque effect is exacerbated with a five-wire balanced harness. To minimize torqueing, one of these days soon I'm going to try making a harness with very light-gauge AN silver wire.

Am I up and running?
Yes and no. I have a loaner compressor, so I have music but it is very noisy and does not pass your stylus on a stationary record test.

I will do the compliant CW arm and spring test once the proper compressor arrives.

I have been thinking about making a longer fixed counterweight rod. The current one is around the same length as original. The issue is making it stiff enough, not easy with conventional materials.

DG - I will make sure the petition of names to the cartridge makers for a wireless cartridge makes it to your house too :^)

Thanks for the info
RK - but it is very noisy and does not pass your stylus on a stationary record test.

...the old dreaded stylus on a stationary record test with the system volume knob cranked to hear turbulence and hum test.....

Air Bearing linear trackers everywhere that depend on clean consistent air delivery cringe at the thought of owners subjecting them to this test.
Its bad enough if they have not been set up to operate in a straight line evenly. But being subjected to a partner pump that is not so great is un-imaginable.

Some of the worst arm/pump relationships I have heard of don't even relate to the quality of the pump itself but its placement. There are some owners in the southern US where winter does not exist. These owners place compressors in their garage (not climate controlled) with a long line going to where their stereo is in a nice climate controlled room kept at 72 degrees F. The garage where the compressors starts air delivery can be anywhere from 30-40 F in the winter at night to well over 150 degrees inside the closed barn on a hot summer day with wildly differing humidity. Imagine the changes to the air as it travels down 100 feet of tubing.

I look forward to your impressions Richard.
