The reduced distortion provided by the UNIDEN alignment is a revelation, a quantum leap beyond what you’ve been using. Before you buy some wacky-priced piece of wire, buy a SMARTractor. You won’t regret it.- Tone Audio 2014 Product of the Year – Accessory
The Acoustic Systems SMARTractor isn’t all that expensive but for an alignment tool it is. It costs more than many spend on a phono cartridge or turntable. However, it is a brilliantly thought out product that helps assure accurate overhand and zenith angle set-up - March 2014 Stereophile.
Mating ultra-precision with utmost ease and swift operation
While the UNI-Protractor represents the most universal and versatile phono alignment tool ever introduced in high-end audio, it is an instrument which - due to it’s complexity and versatility - appeals more to professional users.
The serious audiophile who is interested in aligning - if only periodically - his analog front-end to the utmost precision does look for precision which comes handy and which is easy to operate.
To answer this request we have designed the SMARTractor - a direct off-spring of our UNI-Protractor.
The SMARTractor brings the same unparalleled precise tangential alignment for which the UNI-Protractor earned it’s laurels - PLUS the 0.05mm precise mounting distance measurement of the UNI-P2S.
An unique bundle of features:
The SMARTractor comes with 5 (five) tangential curves combined in 1 (one) template.
the SMARTractor's template is made from 3mm (= same thickness as 180 gr LP) strong premium grade german XT mirrored acrylic supplied by Evonik.
no-error-possible single-point alignment with 3mm deep parallax (for ALL helping lines) - an extreme precise, easy and fast alignment.
super easy to use with 1-point fixed setting for every tangential curve.
all alignment lines are cnc-laser cut hairlines.
incorporates real glass aluminum-frame magnifier with automatic focus jig for unrivaled precise magnified view during alignment.
all 5 tangential alignments are based on true triangular positioning and thus are independent of effective length and thus suitable for ALL pivot tonearms, no matter what their effective length or mounting position.
The SMARTractor further comes with in-built direct mounting distance - P2S -measurement with 0.05mm accuracy.
The total of 5 tangential options of course includes the old audio phono standards set by Loefgren and Baerwald in the late 1930s and 1940s in both - IEC and DIN - norms.
* Loefgren A / Baerwald DIN
* Loefgren A / Baerwald IEC
* Loefgren B DIN
* Loefgren B IEC
furthermore the SMARTractor features the critically acclaimed UNI-DIN tangential curve.
An all new tangential curve which is the latest calculation and the first one which does really take into account the special requirements and circumstances of a stereo stylus tracking a non linear stereo groove with increasing differences between the two groove walls.
The result? - real sonic benefits!
In the last 2/3 of the record's groove, the UNI-DIN curve offers significant (18-45%) less average - as well as less total! - distortion than Baerwald or Loefgren.
Sonically this gives you less stress on human (female) voices, more subtle details, less "grain", increased "air" and considerable more "headroom" in critical passages and especially so in climaxes.
Rest assured - you'll love it, once you've heard it's direct results and merits.
the UNI-DIN tangential alignment is available only in the SMARTractor and the UNI-Protractor.
Now - why 5 different options for alignment of cartridge/tonearm?
The vast number of tonearms introduced in the past 40 years not only displays a large number of different concepts, but also a considerable diversity in geometries.
Furthermore it makes a significant difference whether the record we want to track with best possible results is a modern pressing with a very long run-out/lead-out ('unmodulated groove' or 'dead wax'), or whether the record's groove is cut close to the paper inner label.
The later is often found with countless records made in the early stereo years from 1958 up till 1974.
The SMARTractor takes into account the diversity of geometries found in pivot tonearms - as well as the different situations in records past and present.
The SMARTractor offers the best possible tangential curve for every request.
For every pivot tonearm - as well as for every record collection.
And it makes sure that the serious audiophile gets the most perfect, utmost precise alignment possible.
Even more important, this ultra precise result is achieved swift, with ease and free of any possible error.
No in-deep knowledge nor any special manual skills are required.
Setting up your analog front-end with unparalleled precision - and with the BEST SONIC results obtainable - is only a matter of a few minutes when using the SMARTractor.
While we’ve all been arguing about whether to align our phono cartridge to Loefgren A, B or Baerwald spec, Acoustical Systems has gone back to the drawing board, looking at the problem from a new light: updating phono cartridge alignment from the perspective of modern designs, materials and stylus profiles..
The result is their UNIDEN alignment geometry, implemented with their SMARTractor. Nope, you won’t find this profile for free on your favorite internet forum; you’re gonna have to buy it. Granted, $795 is a little spendy for a user with one table and one tonearm, but we guarantee you will never hear a more profound improvement to your analog system than this provides for anywhere near this price.The reduced distortion provided by the UNIDEN alignment is a revelation, a quantum leap beyond what you’ve been using.

Tony Bolton immerses himself in the world of cartridge alignment with a new cartridge protractor from Germany.
HI-FI WORLD September 2013
" I have found this review fascinating and have come to the following choices of alignment: for my shellac, I will stick to the original Baerwald curve. For microgroove use, both mono and stereo, I shall now be using UNI-DIN. I liked the presentation of the music better, enjoying the greater space and definition of the shape and form of sounds.
I like this product. It is expensive, but the quality of finish, and the precision of the engineering make the cost worth while. It also allowed me to fine-tune a turntable to a better level than I could previously. With the result that my records sound clearer and more enjoyable, which is the whole object of the exercise in the first place."
