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 ?

Ct0517, on my TransFi the "loom problem" is compounded by slightly thicker discretely shielded wires, and by the extra wires required for a balanced circuit. The feather-lite short wand is particularly vulnerable to fouling.

The gantry grommet is about half way across the LP. The loom is dressed like an egg-beater. It expands and contracts as it moves, with the force vectors of the discrete wires approximately cancelling.
Chris: I am in total agreement concerning the sonic gains you must be getting in having the armboard separate from the plinth. If my room were larger, I'd try the same thing. I do however have some new thoughts in mind for a new armboard (replacing the stock one) that could isolate the ET better. I am going to try this at some point when I get my other issues worked out.

I'm totally happy with the "up @ over", and I have no doubt that with the new mounting structure I'm thinking of (will not be mounted to the TT base @ and I'm going to try Frogman's recommendation of the AN wire), I'll be even happier. One drawback with my current support structure is not very much room to access the lever to pull the spindle back. My new one will be mounted to the Symposium base thereby having better access and less vibration.

BTW Chris, 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?

Thanks for the compliment on my motor enclosure. I built it myself. My second try at one. I really learned alot from my first try. It may not pass a WAF, but to me the beauty is in it's solid construction and how it performs. I'm still planning on using a bearing/pinch roller scheme something like Dgarretson uses, that to me will be killer when it is finished.
Once you try thread drive, there's no going back, IMO.
Hi Henry – welcome to the thread.

I will reply to your question with my actual DD and idler impressions later. Need to catch up with the holiday weekend that was anything but a holiday with two soon to be 18 years olds packed up and sent away to college. Now I wait for their phone calls. Damn... now I need to change their phone plans before I get dinged with huge bills. :^(

Correction – replace the word plinth with platter, motor, bearing

The word plinth is one of those bad words – it has been corrupted by analog audiophiles - IMO.

http://en.wikipedia.org/wiki/Plinth

Plinth to me means common platform. All my TT’s have a plinth. How the tonearm, motor, and platter, bearing connect to this common platform varies. There are good designs and bad designs. I have personally found that a well executed- bad design, can out perform a badly executed - good design.

DG - need to look at that tonearm some more. living /breathing egg beater ?
Chris: I am referring to 'plinth' as does VPI when describing their tt designs, and as far as I know, most TT manufacturerers do. I have to say, the wiki link you provided seems to confirm the intent I initially meant. The plinth in my TT is 'the' platform you speak of. The armboard is connected to this 'plinth', (and becomes part of it) that supports the platter and bearing.
Chris: I think I oversimplified my response to this now, I appologize.

Dgarretson: I looked again at your "egg beater" wire loom. Very interesting and "smart" execution. Question, Do the two 'outer strands' of your egg beater design, need to be slightly longer to acheive proper "force vector"? If so, does this have an effect on your balanced cable design?
