Eminent Technology ET-2 Tonearm Owners

Chris -
No I dont have the equipment, but Martin Colloms did in a Hifi News review years ago ( 1985, I think ). He measured the resonances before and after the air bearing and compared them to ascertain how the air bearing dealt with such. Typically you would use an accelerometer placed on either the arm or bearing housing to measure these.
If my memory serves me well the resonance profile remained in tact, in other words even though the resonance is passing through air and rubber, it went through almost unhindered.

By the way - another little tweak for you - I decoupled the rotating arm lift from its bracket using teflon washers/spacers, another small audible improvement.

To everyone..I'm sure that you have experienced this. Last night's listening was great. All the planets seemed to align. So what causes this? Clean power? Just the right room temp, humidity? My own state of mind? Off topic, I know, but I am curious to read your views on this.

Richard your NZ last night is my yesterday still....

I believe in the one and almighty, and in the things that are out of my control.

He giveth and taketh away.

Yes I am talking about the local hydro company. This is an audio gear site.

I was very aware of the power limitations I had, and their effect on my systems in the big dense city. I feel kind of blessed now that I live in a rural area with an abundance of clean, raw power. Sometimes on a few occasions there is not enough (hot humid july/aug nights). Other nights, more often, there is too much above 120v. When the number on the gauge reads between a certain range I have come to know that good things can happen. It then depends on my own mood. Humidity helps. There is more grain in the music for me when the power reads above 120v. Looking forward to converting my table to battery soon. All Power Conditioners I have tried made the bears sound pleasant but like they were on meds. No thank you for the amps. The OTL's coming have their own line conditioners designed for them.

Yes when you talk to Dover and I you are conversing with the future.
I agree with you. Clean power and I think that we should not underestimate the effect of our own state of mind.
I think that every professional reviewer should prefix their review with...,
Today I feel..., or over the period of this review this was my general state of mind.
BTs comments are interesting. I know the effect of the shims and grub screws. It is definitely positive. As in the drive thread, I believe that there should be nothing soft in the loop between LP around to cartridge. The o'rings are quite soft.
My testing, with and without the bearing sleeve clamped seems to support that view.

Chris, the good thing is, if we have a bad day over here we can fly over to your place and start the day again ...

Yes when you talk to Dover and I you are conversing with the future.

Richard/Dover – have you figured out a way to tell me how the stock markets will open in Toronto or New York ?

Small correction to my previous post. humidity is good I have found for vinyl (as we deal with static), but not good for ESL’s especially my Quads which are very sensitive to levels. They like it really dry. So its like being between a rock and a hard place in a way. Still Quad 57 and 63 are designed differently. Some info I got from a respected rebuilder - The 63 panels will be destroyed soon if placed in rooms with high humidity. Not as hardy as the 57’s – now there’s an oxymoron for you.

The Acoustats do not seem affected by humidity – are they like Hercules of ESL’s ? Both in their ability to withstand conditions over time and accept wattage without problems. Wondering if this is due to the amount of space between the mylar?

Cheers
