Turntable advice / opinion on setup / sound.

Every design has to compromise one aspect of performance to excel in others.  There are some designs that minimize most theoretical problems, but, these can be quite expensive, such as the Reed T5 arm that has almost no tracking angle error, no skating force, a long enough arm to reduce VTA/SRA changes from different thicknesses of records, no excessive force required to move the arm horizontally to achieve tangency (unlike air bearing tangential tracking arms), and good resonance control. 

Still, it is ear opening to hear arms such as the Viv Float which sound so good with what is massive theoretical tracking angle error.  They must be doing something very right in other aspects of performance.

Have you had an opportunity to actually set up and experience the Holbo air bearing tangential arm?  The only force required to move it sideways comes from the inertia of the tonearm assembly which weighs under 50-grams including cartridge.  It has to cross an entire record side in about 20 minutes so its acceleration is miniscule 

I have no experience with the Holbo.  The concern with required force to move the arm has to do with the lack of mechanical advantage of a pivot that rotates the arm; with an air bearing arm, the arm has to be dragged to its new position.  This may be more of a theoretical than an actual issue, but owners of some air bearing arms have reported suspension and cantilever failures.  
 

Such arms tend to have very high horizontal effective mass and much lower vertical effective mass.  Some claim this is a problem while others say this is a virtue.  On some records with very deep bass, the bass is mixed closer to mono to reduce vertical modulation; this means wider horizontal movement.  Higher effective mass and the lack of movement as a pivot means that the arm resists horizontal movement from groove modulation meaning that the full bass signal will be picked up by the cartridge and not lost by the cartridge moving side to side.  I don’t know if this is the case, but the airbearing arms I had delivered very powerful bass.

IF I was going to champion a ’rigid’ design, no arm height adjustability, I would do a survey of various cartridge heights, then:

1. pick an average. sell all the 3 point cartridges you can peddle.

use Rega designed/approved shims under the arm mount, or above the cartridge for taller or shorter cartridges. Split shims for the base so the arm does not need to be completely removed. 

It’s purposely making it shorter than ALL other cartridges that I object to.

’ALL Other’ until Ortofon answered the need to make 14mm high versions. Thankfully for the OP, because that is what he chose.

And, the lack of measurements to properly mount non-rega cartridges bugs me.

Many things bug me, thankfully more things make me happy, two among them is the easy on the fly height adjustment of two of my tonearms.
