sd: you are probably too young to remember, but they made all of the same claims in the 70s too. that was the last time that there was anything approaching a major interest in linear tracking arms. yet, for all those virtues, the standard arm persists? maybe its the air pump.

Rube Goldberg for sure.

The bearing for the cartridge holder has grown exponentially over the years, but those pesky air hose and cartridge wiring are awkward, to say the least. Still, that very substantial bearing should minimize binding, but I still wonder about the drag and resistance, particularly as caused by that air hose.

Whoa. If I ever entertained thoughts of buying one of his products, that would put me off. It would have served him better to show more about him actually building his TTs rather than spouting off inaccurate crap about digital vs. analogue. Oh well...

Thanks for the link.

Dave

a liked susan. the first part was great, about 30 seconds, then the last little bit where he talked about hand making his products, about 30 seconds. the middle could have been filled in with more susan.

how about a picture resize, self?

Me too. I've got broadband and like to use it.

Are people still on dial-up???

Dave

nope..no dial up..just the damned picture is too wide to fit in the screen.

i hate to click the slider to see another side of a picture.

pure laziness.

I am shocked by the willingness of the contributors below to express views based solely on visual impressions.  This is of assistance to no-one and makes the writers appear ignorant which does them no credit.

Have any of you actually heard this piece in action?   If not, kindly keep your views to yourselves.

In fact Aeroarm performs superbly and is the only fully successful parallel tracker I have heard.  Yes it needs careful set up but certainly no more than fixing a cartidge at the correct difficult to ascertain angle in a pivoted arm.  Lateral levelling is critical but not difficult to achieve using a base support at one end that has a screw adjustment.  Levelling is best carried out in realtime using an uncut disc, commercial levels are nowhere near accurate enough.  Being parallel, cartridge alignment is all in straight lines against protractors and so takes far less time than on a pivoted arm and the result is always perfect.  Once set up it will hold its setting forever.  Correctly dressed, the soft latex air line and the vanishingly fine signal leads exert far less force on the arm beam than the signal cables on many 9 inch arms (eg how to dress your Linn - with great difficulty, I had one).  Think about it, if these connections exerted any significant force at all, the stylus would skip the groove since only that interface only is what drags the arm along the arm beam.

I team this with the Simon Yorke S10 and Ortofon A90.  The synergy with A90 is made in heaven, both lightweight high compliance.  Compliance with cutting head parameters is only a small component of why this is far better than any pivoted arm - after all, pivoted arm tracking error is tiny.  The main reasons Aeroarm works is because the effective pivoted length is a quarter of that on a 9 inch arm and effective mass also around a quarter of most 9 inchers.  Thus it is far faster and more compliant than any competitor.  Just watch the way it rides a badly warped LP, where a 9 inch arm is launched into orbit.

I won't go into further detail here about the performance.  Those interested may refer to a review I put on Simon Yorke's site.
