Eminent Technology ET-2 Tonearm Owners

With the stylus down, how is everyone's I-beam angled?  Is it perfectly horizontal or a little down at the counterweight end?  I have the long I-beam and the counterweight end is currently a little lower than the spindle end, but I really don't see a reason to not adjust the I-beam so it's horizontal.

"Normally" the I-beam is in line with the tonearm, ie. "horizontal" tonearm & I-beam.
(I think that's what you see in the manual.)
"Underhung" - which is popular and necessary to a degree with unipivot bearings, the I-beam would slightly slope down to the end. But... this is neither necessary for the ET2 nor does it make sense dynamically.
If not going "normal" I'd try to slightly lift the end of the I-beam, meaning to set the counterweight sligthly above horizontal.
Dynamically it is IMO optimal to have the line from center of mass of the tonearm & cartridge to center of mass of the I-beam passing exactly through the center of the bearing tube.
The beautiful thing about the ET 2 bearing is: It works admirably well even without thinking too much about such issues :-)
 

I've been away for a while as I was lured  by the lazy ease of streaming digital.But now I'm trying to get back. I recently bought a used Sota Cosmos (arrives today) with all of the most recent updates. My plan is to try my ET2 on the Cosmos, as I already own a Cosmos armboard for the ET-2. I've owned an ET2 on a Sota Nova for at least 30 years. So you could say I am experienced, and actually came up with the idea for the long ibeam with minimal weight way out there. My problem is the airpump for the ET2. Right now I run two Wisa pumps running out of phase, with a large surge tank, and the highest pressure I can generate is about 7-8 psi.. I'd like to do better. I've skimmed the last 3-4 years of posts and could find nothing about pumps. Has anything new and better been discovered in the last 5 years other than the shop and dental pumps?

Thanks for any help,

John

I'll answer my own question. I googled air pumps and found a "Silentaire Super Silent 20" pump on Amazon. It's expensive at $600 but very quiet at 30db. I tried a shop pump from Granger a while ago. The higher pressure (20psi) produced a very black background but the noisey pump  was too much. So, I returned it. Anyway, opinions about this pump would be appreciated.

The key to using a shop compressor is to have a large enough tank for at least one listening session.  I can listen to LPs for days with one fill of my 60 gallon tank.  It's the most quiet air source you can possibly have and there's no need for a surge tank.  I waited years to connect it to my tonearm, and once I did, I felt stupid for not doing it sooner.
