Stitch,

the only thing that you are missing is paying attention to the OMA advertisements and truing to recognize behind it any rational beside a pimp yearling own merchandise (in fact it is not his merchandises). I told many times before that brain, ears, knowledge and listening awareness behind that Pennsylvania dirt is sub-acceptable and I would like do not be induced to comment on it again and again. Ironically, there is a manufacture in your country who dealt with the OMA dirt before and who after read my site sent me email with surprise how much I know the OMA under-hood.  He even proposed to upload in the site some of his anecdotes about OMA that in his view would make everyone se that his Pennsylvania dirt is not “nothing” but something that deserve to be squashed and destroyed. I refuse as I do not feel that truth about OMA need any “evidence”.  So, please let keep the OMA out of scope of any further attention. The only thing that would make me happy if a lighting strike the dirt, kill him, burn his house with all crap the he is trying to sell and preferably any single person who deal with him. Is it too much to ask? Jonathan Weiss of Oswaldsmill Audio is an audio equivalent of neo-cons in US politics – he uses the identical methods of capitalizing on fears and stimulation of parochial thinking.

About the Idler Drive turntables. Yes, you never see any serious thinking about it. In the best cases you see the people swear own devotion to idler TT but in all cases I was able to recognize a flows in logic and their desire to advance this or that method of transforms momentum from motor to platter. Can we presume that if DD, Idler or belt TT – all of them made with identical respect to own topology then will produce identically result?  I presume that it might be so, but I am not certain.

I have seen a few years back an article in Russian magazine where the author was trying to prove that Idler roll is the most preferable transmission as it forms a mechanical filter of lower order. Here is the link (in Russian):

Saying it, I have to note that the author of the article is well knows falsifier who have a reputation to write fraudulent articles and to conceive counterfeit to ideas into public to fulfill specific marketing campaigns. Still, the conclusions in the articles are not wrong – an Idler roll does have some transfer advantages … but for very light platters. With increase of the platter’s mass I think any theoretical advantages get equalized or completely reversed. Where is the truth? It is hard to say. It is VERY difficult methodologically honest to compare TT.  There is so many valuables involved!

The Idler Drive looks like coming back. So, a few years back it was the microprocessor controlled DD. Before it was a belt or a combination of belts…. I think it is a purely marketing circus invented by idiots of Framer- Weiss level. When SME made 3012 then if few years the pips sold very expensive bronze bearings on this arm. There were a number of highly scientific and serious articles about advantage of bronze over steel. Then the same was reversed to plastic bearings. Then it went to second round and the advantage of steel was rehabilitated. Over the years each 5-6 years the fashion on the preferable 3012 bearing was rotating…  I think the same is with Idler drives. A few companies would like to make them and they make the “market makers” to spread new set of “believes”. A dozen of so on-line cronies join the chorus and the “new” revolutionary topology is born. Isn’t it how the industry proper itself? Have you read TAS blog and alike?

What is important to understand however is that revoltingly-unserious level of industry treating the different technological aspect (Idler Drive for instance) is not necessary an indication that the given technological aspect is wrong. We just do not have any answers as the audio industry never care to ask any complex or deep questions.
