Does any Audiogon member have a Holbo air-bearing turntable?

Nothing arrogant about stating that something appears to look inadequate. I didnt say it was I said it looked. Dont interpret, read what it written. If you search linear tracking arms one of the cons listed is the complexity of the arm as well as the significantly higher cost to manufacture. Just admit that my statement offended you at a personal level and you responded as would a delinquent. 

In terms of tech and similarities between your arm and the CS Port I would guess the manufacturer told you this. I would also guess that much of the tech from both arms was taken from earlier tangent arm designs and hopefully improved upon. The first tangent arm I remember seeing was the Eminent arm which suffered from problems intrinsic in this type of design.

So my statement was based on fact and a decent familiarity with this design. I think this design has merits, but also a great many problems which are best dealt with by throwing money at the design and most critically the materials used. Now to help you out I am not stating more expensive products are always better. And lets confine this statement to the components in this discussion.

I did not know about Allclear Audio - thanks for the tip (sorry, another pun).  Garrott Brothers is another Aussie service that has been mentioned here.

2L.no has started producing vinyl records but I don't have any yet.  If fact, not much of their production is classical so they get lots of Grammy nominations. My current rule of thumb is to buy SACD or Pure Audio Blu-ray if they are available, then vinyl, then CD.  With 2L.no you mostly get SACD and Blu-ray versions in the same pack.

Norway distances are about as intimidating as Australia's, but with a lot more bends and gradients!  Whereabouts do you live?

Far from it.  It does not take much for somebody with a science / engineering background to understand how most things work.  As I see it, there are two big differences - but as I have never got my hands on a CS Port I could be wrong.

The Holbo has a tubular air bearing riding over a passive shaft.  Air is fed into the bearing itself which is very efficient and only needs a very small airflow.  The CS Port seems to have a half-tube bearing riding on a shaft which contains the air distribution ducting, so my guess is that most of the air is wasted. Bigger pump, more noise.

The other big difference is that the CS Port has a removable headshell.  The headshell plus cartridge must have a mass of 20-grams or more (from CS Port’s website).  Instead the Holbo has a solid platform to mount cartridges directly to the arm, which is obviously more rigid though less convenient than a removable headshell.  The tonearm mass is just 31.6-grams which, together with the cartridge (say 7-grams), makes up the inertia that has to be moved sideways by the stylus to provide tracking.

That's why the Holbo is a breakthrough product.  In terms of materials and manufacturing costs, my take is that high precision CNC machines are the big secret.  The Holbo makes use of a small number of components with simple shapes assembled into a brilliantly simple but highly functional design.  The polar opposite of the Garrard 301.  There apparently is more than one way to skin a cat.

I appreciate this response. How I would like conversations to evolve and I admit I am sometimes the cause of any deterioration. 

I also am not a fan of removable headshells for obvious reasons.

What is paramount is that you are a fan. I am very happy with my Tri-Planar and Merrill-Williams setup but always on the lookout for effective ways to improve the experience. 

My digital setup is modest in comparison to my analog front end. Not a fan of digital but a fan of what may come with streaming.
