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 ?

Hello all,
Been away for a few days.  Drove over to Nashville for a long weekend of live music.  The venues were pretty terrific and I was afraid I wouldn't be able to listen to my system when I got home.  Not so.  Turned on the system, warmed up the tubes and it sounded excellent.  Not live music but still sounding great.  I think it does us well to walk away for a few days.

Frogman, I received the arm board. Thank you much.  Going to wait a while before trying it out.  I'm very pleased with what I'm hearing.  The mag arm wand was a nice improvement.

John, my plugs and resistors arrived while I was gone.  I'll try it out later this week but I've got nice tight bass and nice cymbal shimmer without brightness, straight into my CAT at 47k ohm.  Like you, I think my ET II tweaks are showing my Delos at its best.

Glad to hear that Harry. Did you visit the "Bluebird cafe"? I'd love to make a visit.
I'm excited about a new acquisition, arriving on Wednesday. -An Allnic 1201 phono preamp. It's tubed, but uses a transformer based input. I'll have to stick with the lower impedance loading on this piece, as the unit has a max of 260 ohms which is what Jon Carr recommends with the capacitance of my cables.
This is uncharted territory for me, as I've never used step-up transformers on low output cartridges. I hope it's a step up for my system. I'll write a f/u.
Best to all,
John
John,
Tried to go to The Bluebird for lunch not realizing they were only open for dinner.  By then it was too late for reservations.  Good luck with the new preamp.  Let me know how it works out.  I've never used a SUT either.

Hi Guys
Look forward to your impressions of the Allnic John. Harry would love to check out the Nashville music scene one day ...

Of note on the loading discussions. Taken from Lyra website

Kleos

 Recommended load directly into MC phono input: 95.3ohm ~ 816ohm (determine by listening, or follow detailed guidelines in user manual)
 Recommended load via step-up transformer: 5 ~ 15ohm (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)

Delos

 Recommended load directly into MC phono input: 97.6ohm ~ 806ohm (determine by listening, or follow detailed guidelines in instruction manual)
 Recommended load via step-up transformer: 5 ~ 15ohm (step-up transformer’s output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)

***********

My XV1 has a recommended loading of > 30. I have run it full out 47k with no issues.

From this thread..

There were good takeaways for me from J. Carr on that thread, from quite a while ago.

J Carr

Generally speaking, the greater the capacitance across the plus and minus cartridge outputs, the heavier the resistive loading needs to be to control the resulting high-frequency spike. Conversely, less capacitance allows the resistive load on the cartridge to be reduced, which will benefit dynamic range, resolution and transient impact.

*************

PS. The possible frequency range occupied by the high-frequency resonant spike also includes the frequency range encompassed by LP pops and ticks, and these can likewise be of quite large magnitude (larger than any music signal inside the groove). Just as with the high-frequency resonant spike, controlling pop and tick energy is the task of the phono stage (although it is a big help if the cartridge has a low-mass moving assembly). The phono stage and cartridge can have an immense influence on how "noisy" your LPs appear to be.

^^^
It highlighted for me also, how important a role the direct shot wiring plays. I am sure it plays a big part, along with my phono stage, for the reason I am able to run with no load.

Cheers Chris

Hey Chris,
Thanks for the link to that rather involved discussion of the interaction of cartridge, interconnects, and loading. I must say I'm more confused than ever, but have learned a few things.
Has anyone taken into account the break in of the connection between cartridge and phono pre? With only millivolts on the cable, does it ever break in, and stay that way, if you believe in such things?
I got sold on a new interconnect by "Allister" at Audioquest, incorporating the DBS system. -Never used DBS before, but seemed like a good idea for this application.
I imagine it will beat my 25y/o AQ diamond IC's. An AQ water will arrive tomorrow. If it doesn't work in that application, I'll try it elsewhere in the system.
I'll get back to you about that.
John
