Unipivot vs Linear Tracking


I set up my first Unipivot arm night before last. It took roughly 5 hours to set up and I am still tweaking various parts and cartridge, what a work out. The arm is a Scheu classic with the Scheu Premier I turntable and a Scheu Benz cartridge.

Now I have two questions for the Audiogon club.
1. Do you consider linear Tracking superior to Unipivot?
2. Which would you say is harder to set up properly?

Mikelavigne and Raulruegas are the guiding lights here. Technics applied more money, expertise and R&D muscle to the development of the SP-10 series than all modern turntable manufacturers combined will acces during their lifetimes. You have to remember that this was the mighty Matsushita corporation at the peak of their high end audio venture. The SP-10 was subsidized by the sale of millions of mass market turntables. No one will ever sell turntables in those numbers again. I went from a Well-Tempered Reference table to an SP-10 MK II and it was a leap upward in terms of stability, authority and even quiet. And let me say that very few of you currently own a quieter table than that WTT.

Raul's point about set-up is also very strong because the matter of which design is optimal becomes moot unless both comparative units are optimized. While you are amazed that moving your speakers an inch makes a big difference, you must then realize that moving your stylus forward .2 mm or rotating it one degree can make as big a difference. I have a Technics EPA 100 MK II tonearm with a variable dynamic damping system built into it. This allows adjustability in damping of the arm to accommodate a wide range of cartridge compliances. I've noticed that very small changes in my damping adjustment can affect the sound of my system in significant ways. I would guess that no LTT could match the performance of this pivoting arm without a similar damping capability unless the cartridge match was absolutely perfect.

Some while ago I started a thread about the relative merits of belt drive and direct drive. It went on for quite a while and generated some pretty emotional observations and banter. Ultimately nothing was really resolved but the same result became apparent there as what we are seeing here. People seemed to agree that implementation was more important than the fundamental design approach.

Many years ago I had the first version of the ET tonearm and I could use it happily today if it was a little more user friendly and convenient. I knew less then and maybe I'm being naive in my recollections about it but I mention it because I have experience with both. I've also owned the B&O 4004 LT table and a Yamaha PX-2. I don't really have a preference. I am starting to see, however, that a lot of the best products to come along in history were provided by manufacturing giants. Led by reviewers, we have tended to overlook them in favor of home based garage creations with gimmicks , panache or political connections. This old Technics stuff is absolutely killer.
If you have the time and motivation, set aside a long weekend with all the KAB 1200 modification kits and apply them to a factory fresh Technics SL1210MG5 one by one and you will be impressed at the outcome and with the changes of each along the way.
Well,first off my apologies if I seem to be attempting to convince anyone of "anything" being better than anything else....This "is" a hobby topic based forum,so I think I'm playing within it's parameters....

Raul,I am sure that though it is completely possible,and definitely probable that I have "not heard the "perfect arm/cartridge combination",I'm confident that "those" that I "have" heard were just as "viable" as any you have been exposed to -:)OK?

I'm totally happy to get off the apparent soap-box,some think I'm on,regarding the linear/air bearing subject.....anyone knowing me(from Audiogon threads)should realize that I like to "go on" about certain topical subjects....Those which appeal to my own "personal" thoughts....I DO admit to "loving" this subject.

I really don't have any vested interest in convincing "anyone" about "anything",and the subject of linear/air bearing designs came up,so you have my "opinion"....If anyone thinks it is ego driven,then I am truly sorry....'cause it is ONLY "hobbyspeak"!...ALWAYS WILL BE -- "JUST THAT".

Now,for the curious.....

A few months ago,Hi-Fi Plus ran a superb article/review comparing a few highly regarded 12 inch arms(they actually ran two seperate reviews,but I'm speaking about the latest article)....The review and "somewhat comparisons" included(from memory)the superb Brinkman 12 incher,a "way cool looking"(yet looks to be a Triplanar rip-off)Chinese Unipivot(the Tri is not a uni,but the resemblance to it is almost incriminating),another high priced pivot AND a comparison to a "very reasonably priced" air bearing/linear design("this air/LT arm was at least half the price of the pivots in the review)....

The reviewer(yeah,I know,don't believe all reviews)loved a few of the pivots,but what stood out to me,was his enthusiasm for the Linear/Air bearing "el-cheapo" design!They are not ALWAYS expensive.

His impressions(opinions)were to describe the "sonic signature" as they appear to anyone with enough exposure to the "flavor" of this type of analog instrument....Basically he loved it,and felt in the area of "lack of a resonant signature" it was magical....Not the exact words,but close enough....half the price of the other commonly preferred pivots(which are great arms,btw).

There was another online review of another very low priced air/linear tracker(I "think" it was on Enjoy the Music site),where the "exact same" enthusiasm was relayed to the reader,but "that" arm was even lower in cost than the first!I don't think it was more than around eight hundred dollars,but the owner is supposed to buy the pump,which as designed is not expensive at all(think aquarium pump pricing)....

Here we had two quite low priced LT/Air Bearing arms(they are not all priced in the Kuzma Airline range),where the enthusiasm of the particular hobbyist/reviewer was "way over the top" for the arms in question,and the comparisons to the "High Priced" pivots were eye opening....What can I say?....I'm sure there is plenty for "some" to nit-pick here.

My point is "ONLY" for those interested in persuing this type of arm(I believe the question "was" asked on this thread)....

Myself?....Well I have always been happy with my Graham arms,and have no interest in making any changes...but I can attempt to be open minded,and offer an "opinion",based on exposure....Like everyone else!

You can agree,completely disagree,or find some detail to nit-pick....

It's all fine by me! -:)

Dear Sirspeedy, Can you recall the name of the LT arm that was used as a comparator in that review, OR can you supply a reference to the article? Sounds like there was only one well recognized top quality pivoted arm involved, the Brinkmann. The one or two reasonably priced LT arms that are now currently on the market do interest me.
And by the way, what is the significance of all the quotation marks you use around single words and phrases?
The Cartridge Man is the first arm,I believe!I cannot remember the second one.Btw,I did hear the Brinkman this winter...thought it was beautifully made,and loved the sound of the system it was in.

Why the concern regarding my punctuation?
