Linear Tracking or Not?, Any Experiences and Recs


I am considering the advantange of a linear tracking tonearm compared to a bearing or unipivot arm. From my uderstanding there is no arm that can compare. Is this true. Does this make the top of the current arms not worth considering. Are there any cartridge that will reject or demand the use of a linear tracking arm. From what I understand some carridges won't work on a linear tracking arm, as well as several turntables.

I started using a Kuzma Airline a few months ago and despite the horror stories about these kinds of arms, I have been enormously pleased. Once set up and properly aligned, it is non-fiddly (I did initial set up pretty easily on the Kuzma XL table, but it was fine-tuned by Bill Parrish at GTT, who knows the arm and brought it to a fine point). Setting VTA is brilliantly simple and repeatable.
As to bass, and overall performance, I can give you the following insight- I had bought a Kuzma Reference table and the latest Triplanar, using a Lyra Titan i. The rest of the system was essentially unchanged. Pretty impressive bass (I use Avantgarde Duos, to put this into context) and quiet, dynamic and musical performance. I then switched to the Kuzma XL table- very high mass- and the Airline. More air around and body to the instruments- the bass became far deeper, if a little less pronounced higher up in the spectrum, and the sense of palpability- of real instruments and voices in space- not just a mirage or hologram, but real, with tonality and substance that wasn't there in the more modest set-up. (I grant you, some of this may have to do with the TT upgrade. And with the use of a far better platform for the TT. But, initial comparisons were without the benefit of the finite elemente platform now being used).
There is also less of a sense of a record playing- hard to describe, but when you don't hear it, you realize what you are usually hearing from a phono source.
The compressor must be in another place other than the listening room- it is noisy, it spits and farts, and is an otherwise serious piece of industrial gear. The quality of the arm itself is immediately apparent visually- overbuilt, fairly simple, and so far flawless in performance. I had an ET2 back in the day, and while it is unfair to compare, given the difference in price points-the ET2 was a bargain-
the Airline is an absolute revelation.
As to the need for a vaccuum table, maybe I am not getting the last iota from the XL, but I find that hard to believe- the record clamp does a great job, and the mass of the TT/platter assembly makes for a dead quiet listening experience. But, I'm certainly willing to be educated on this as well.
I do try to avoid warped records- I find it wonderful, after returning to serious audio from a 10 + year hiatus, to find so many, many great recordings now available as reissues on vinyl. (Not to say that new vinyl doesn't have problems, sometimes, but when I last left this hobby, the only source of vinyl was squirreling around in bins at used record stores, or worse- the Internet was not a force to be reckoned with either).
Anyway, I am also more sensitive to how much I clamp a given record since too much force can obviously cause the record to bow. The Vta adjustment on the Airline arm is sooo easy, you'd really be remiss not to adjust it for each record. (I used to think that way lay madness, but at the time, had a Well-Tempered set-up and it wasn't as easy). BTW, I don't bother with the Vta adjustment on the arm tower, which as sold with the XL, is also adjustable and has an electronic micrometer. Instead, I use the adjustment on top of the arm assembly- easy as heck.
Is a vacuum system really intended to compensate for noticeably warped records? I assumed it was to create a bond between the platter and the record, to avoid some kinds of sonic aberration, like 'ringing' or resonance. I suppose that could also take care of mildly warped records, but is it really meant to? (Or is it just a question of degree, and all records are 'warped' to some extent?)
Uh,oh. The Madness is coming on... :)
