We were allowed to post this article by Mr. Paul Stratton in UK.

Intrigue got the better of me (yet again) after discovering this by chance, so an order went in and on return from a trip overseas, 
it was waiting here for me. I didn't intend installing it just yet as my TT is not fully finished but the other night thought ok, let's just 
give it a go and spent a couple of hours swapping the Art 9 over and getting the set up spot on with my laser engraved protractor 
specific to my SAEC WE506/30. Prior I was using SAEC ULS-3x, sintered aluminium oxide which is extremely hard material and 
very very stiff. This is the top SAEC headshell. Though I have not used any other shell's on my arm, I do have access to several 
through friends but was always contenet with the ULS-3x, so just stayed with it. 

Anyway, the improvement that the Nasotec is claiming is to 'reduce', not eliminate error, from a pivoting arm. There is plenty of technical 
info on their website about why and what they are aiming at with this. Does it make any difference? Yes, it does. After the first few 
notes on Tracy Chapmans wonderful debut LP, it was obvious that the claims are backed up with ability. Notes seem to just flow 
unconstrained, at ease, with what I had considered more background notes, ambience etc coming more to the fore, bass in particular 
has very good texture and clean decay which really fleshes out the sound. A dozen or more Lp's simply confirm this, and last night, 
my Antal Dorati-Decca DMM-Stravinsky Rite of Spring sounded better than I have heard before, anywhere, truly captivating from 
beginning to end.

I imagine that the Nasotec gives a taste of what a tangential gives, and is a good option for many vintage arms out there & still in use. 
Floating with crisp imaging free from speakers is what this brings, possibly not to the level of a good parallel(?) but very very enjoyable, 
so much so that the cost is not an issue for what it does.
