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

Both arm and turntable are still made.

Nothing in the Audiogon ET 2.5 discussion group about this particular combination.

What I say to Mijo is that there is another opinion regarding horizontal effective mass that is espoused by some who are at least as intelligent as he is and just possibly better informed in this particular area of engineering than he may be. He seems close minded to any other view but his. I actually think it’s an interesting question. we have tangential tracking tonearms, most of which would have a high horizontal effective mass compared to their vertical EM. We also have the Dynavector tonearms and several other pivoted tonearms, like Moerch, that actually sport added weights extending laterally from the pivot, in order to increase horizontal effective mass. Some of the FR tonearms have a lateral balance weight that probably increases horizontal effective mass. If anyone can think of other pivoted tonearms similarly designed, it would be of interest. Meantime, I invite Mijostyn to read the owners manual for a Dynavector DV505 tonearm, which is available on Vinyl engine. There he will see a rationale for designing a tonearm to have a high effective mass in the a horizontal plane. The reasoning espoused by Dynavector engineers is not far different from what Dover stated. How Dynavector achieves this is very sophisticated. Finally, has anyone noticed that the class of tonearms that present a high horizontal EM compared to their vertical EM is plagued by “blurry” bass response? (But of course you and I might not notice that due to our low IQs.). I do not conflict with Mijostyn due to any personal animus. What I object to is his frequently stating his view as established fact, when it is just his view or that of his favorite guru. It’s fine to state an opinion, but be a little humble.

Mijo, you tend to argue using only your own carefully selected facts and beliefs as support. I am not qualified to comment on the ET tonearm because I’ve never owned one, although every time I’ve heard it, it seemed excellent. I am only focusing on your repeated insistence that the effective mass of a tonearm must be the same in both the vertical and horizontal planes. Else performance at bass frequencies will suffer. As you know, all Dynavector designs deliberately result in high effective mass in horizontal motion. Horizontal motion is also magnetically damped. Many other pivoted tonearms are similarly conceived. You might want to read a Dynavector owners manual to appreciate why their engineers think thi is a good thing. As a long time user of the DV505 with a wide variety of cartridges, I can tell you the DV produces particularly excellent, well defined bass frequencies.

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.)

The force generated by the friction between stylus and groove while playing an LP is usually termed the skating force.  The force we apply in our half-assed efforts to equalize it is "anti-skating".  delm, I am sure you know this.  Just wanted to keep our terms defined.

Wow. What a match!!! I would say no, because the ET justifies a much better TT, and the Transcriptors has a springy suspension which may be thrown out of balance by the heavier than average ET. The Transcriptors was indeed a wonder when it was au courant, and I owned one too, but the design is flawed, though beautiful and stimulating to watch in action. Not that it matters, but I also think the two together would look rather odd, because they emanate from two totally different schools of audio design.
