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 ?

I just did the tests with a 60 gallon air compressor from 2 to 14 psi. The setup was:

60 gallon air compressor @ 120 psi>water separator/filter (5.0 micron)>pressure regulator @ 25 psi>coalescing filter (.01 micron)>pressure regulator>Defender 510M air flow calibrator>tonearm.

I updated the chart with the new data:

Frogman: I really appreciate your "measured" responses! I, on the other hand, am quite the opposite. I know that I don't take the time to explain my position, so I'll give it a try here.

Steely Dan: I think I am much harder on them, given their history of making awesome records. The Nightfly ( I have two copies), while it is much more open (a somewhat general term I am using), it strikes me as irritating in a way that I can't enjoy listening to it all the way through one side. IMO, it sounds somewhat unnatural and slightly "in your face". My comparison, while not the best, to "Aja", I think is telling.

I have three copies of "Aja", none of them I'm confident are the 'best'. (This is where I may separate from some). I am very aware of different pressings and how they sound. My yellow label ABC seems to provide me with the most enjoyment of the ones I own. With regard to these 3 lps, they are, in my words compressed, (with this one having a wider sounstage), as are a lot of SD lps, but the difference between the analog era and the digital era is apparent to me. While I notice this difference and understand all of what I've laid out, I can sit back and enjoy "Aja" all of the way through. I cannot do this on "The Nightfly". This is even though I love the music! To me, it's all about the enjoyment, the escape, the freedom I feel when I take the time to listen.

I do want to say my comments about "The Nightfly" were in no way a reflection on anyone here, just my personal view. I hope anyone here who's willing to take the time to compare, will respond.

Here are a couple of very good recordings in my view:

Chris Isaak "San Francisco Days"--- sadly out of print

Mark Knopfler @ Chet Atkins "Neck @ Neck" -- again, sadly out of print.

Both worth the price necessary to have in your collection!

I hope everyone had a great Thanksgiving!

....I tend to post 'in pieces'.

Just wanted to mention that the two lps I recommended earlier, even though they are or the 'digital age', in my view, are again examples of recordings done "right" as opposed to "The Nightfly". I can listen to them and enjoy completely.
In closing.... it seems unless there is some sort of 'reference' established regarding differences in what we're hearing, the whole process is for not. That's kind of what turned me off with regards to comparing the Acutex in our differing systems.
Ketchup, thanks for sharing the data. The question then becomes: how do the different flow rates affect the sound when PSI remains the same? Did you notice differences in the sound with different pumps with the regulator allowing the same PSI? Of course, flow rate would not be the only variable. While I don't have any data on this, I am very aware of the beneficial effects of using a surge tank to smooth out the pulses of air; which, presumably, have different characteristics from pump to pump. What were your findings re the sound when using the compressor and higher PSI (and smooth, pulse-less air stream)?

BTW, I have the lighter magnesium wand which may partly account for the positive results that I have gotten with the Acutex 420. I plan on trying the aluminum wand and will report back.
