Does the Eminent Technology 2.5 arm work well with the Transcriptors Reference turntable?

As Mijo well knows there is a valid school of thought that supports benefits associated with tonearms having a high effective mass in the horizontal plane Because extreme low bass frequencies are encoded in horizontal motion of the stylus and because they are high in energy content you want the pivot to be stable at those frequencies. Else the tail can wag the dog. (The stylus can move the pivot from side to side.)

@lewm

He is completely ignorant

The horizontal effective mass is almost twice that of the vertical mass. This puts the related resonance frequencies is disparate locations. The end result is messed up bass one way or the other creating not just creating problems with the quality of the bass (most people are not sensitive to this) but also the ability of the cartridge to track correctly.

The differential mass in the horizontal and vertical planes results in 2 much smaller resonant frequency peaks ( instead of one large one ). This reduces the amplitude of resultant resonances further up the audio band by several db, resulting in better tracking and more linear bass response.

The test results are all documented on the Eminent Technology website, which it would appear mijo cannot be bothered to read.

@frogman

I don’t think he has a beef, he simply does not understand how the ET2 works and is not interested in finding out. Of course there may be other reasons for continually making outlandish unsubstantiated claims, but I’m not a mind reader, I can only surmise.

@lewm , That is wishful thinking Lew. The suspension has a certain compliance that is is essence omnidirectional. If anything vertical compliance is lower than horizontal which makes this problem worse! There is a reason that no tonearm of this type has gained universal acceptance, they perform poorly and this is easy to demonstrate The problem is that t most people, on most systems, they sound OK and of course if "I" use it it must be the best and it looks cool. The same is true of 12 inch tonearms. Only academically challenged people buy into this type of thing and you are not but I get it, you like to argue with me which is fine. It keeps me sharp and I learn. You can not argue with the physics. People almost universally prefer the Kuzma 4 Point 11 over the Airline.  

@vinylzone , meh? That lady on the cell phone is about to crash into you. I suggest you close your eyes.

The late Brooks Berdan---well known in the hi-fi business, and referred to as Mr. Analog---probably mounted and set up more arms & tables than anyone else in history. He was one of Bruce Thigpen’s first dealers, and mounted a LOT of the original ET arm on his then (1980’s) favorite table---the Oracle Delphi.

Brooks---having worked in the race car field before entering the hi-fi business---recognized the Oracle had a non-optimum mass distribution in it’s floating subchassis, and came up with a mod to eliminate that fault (Oracle eventually incorporated Brooks’ idea into the Delphi). He may have noticed the Oracle’s mass distribution problem because of the way the moving mass of the ET arm affected the subchassis suspension of the table; It was inherently unstable if left stock.

When the TNT was introduced by VPI, Brooks favoured it for use with the ET arm, as the TNT provided a much more stable platform for the ET---higher in mass and having a stiffer spring suspension. Brooks sold that ET/TNT combo for years, installing one in the system Bill Johnson had in his winter home in Palm Desert, about an hour-and-a-half hour drive east of Brooks’ shop in Monrovia.

Both Bill and Brooks are gone, and the TNT is history, but the Eminent Technology arm lives on! 

Brooks continued to race cars after he got into hi end audio. His widow runs his shop Brooks Berdan Ltd. still in Monrovia at the same location. His son Brian Berdan started his own hi end shop Audio Element in Pasadena California. Bruce Thigpen is building an ET arm for me as we speak which Brian will install in an Oracle. So it's back to the future.

On Dover's advice, I got a Moerch arm for the Transcriptors. I have the Moerch. Waiting on the Transcriptors to be built. Will use the Van den Hull Calibri Grand Master. Dutch needle, Danish arm, English turntable.
