Review of the SMARTractor and SMARTstylus


I mounted an AudioTechnica VM95ML on the Sota for it's new owner using these tools for the first time.

The Acoustical Systems SMARTractor: On taking the unit out of it's box you immediately get the feeling you are dealing with a fine precision instrument. Construction quality is through the roof. It is child's play to set it up. The only kink I ran into. It was very difficult to push the locator pin (points to the vertical axis of the horizontal bearing) through the beam. I had to tap it with a small hammer. The grub screw was backed way out. The nylon plunger used to prevent marring the stainless steel was a very tight fit. 
You set the alignment by removing the pillar's locating screw then twist the pillar lining the index mark with the line labeled  with the alignment you want. I chose Lofgren B. You the place it on the platter which you should lock in place, line up the locator pin with the horizontal bearing and lock the beam in place. The Syrinx made this easy as it has a perfect dimple right over the horizontal axis. Next you place the magnifier in it's bracket and line it up with the Lofgren B grid. The grid lines are super fine and close together. They literally light up on the mirrored surface. Super easy to see.
You line up the cross hair with the targeting grid on the mirror. This puts your sight line right down the cantilever and boy does it work! The magnifier makes it darn easy for old eyes to line things up perfectly. 

Now for the SMARTstylus. This is just a piece of plexy with four sets of grid lines, vertical, horizontal and SRA, and VTA. It comes with it's own hand held magnifier. It looks well made. It is also close to worthless with an offset arm that has a permanent finger lift. Both the offset and the finger lift keep you from getting it close enough and angled correctly to the cantilever. I will try it again with the Schroder which does not have a finger lift. 

In short, the SMARTractor is a brilliant, well thought out devise manufactured to the highest standard. It is handily the most accurate, easiest to use cartridge alignment tool I have ever used. Is it worth $700? I have to say that if you love vinyl and want to be sure your cartridge is dead on, Yes absolutely. On the other hand at this time I have to say that the SMARTstylus is a waste of money. The VM95ML? Darn! It punches way above it's price point. It is handily the best sounding under $200 cartridge I have ever used. It is neutral, tracks well and is very quiet. It is as quiet as my $2000 Charisma. If you are after a MM cartridge in this price range you can not go wrong. You can be perfectly comfortable buying it blind.  

Hope this helps people,

Agree.  No regrets on spending the $700 for the SMARTractor.  However, the SMARTstylus was a total waste of money - its worth about $25 at most.  Tried to return, but store would not allow.
Agreed on both counts.
SMARTractor-fabulous and easy to use.
SMARTstylus- which I purchased because I loved the Tractor--a waste.
I have something similar. Put it on the side without the fingerlift to see if the headshell is level. I think the price on this is high. You can find similar items for less on-line

The question I have about this is that if you don’t have an arm with a perfect dimple to set the arm to pivot distance, can you ever really achieve maximum accuracy just eyeballing the pivot? I have an old Dennison Soundtractor that also requires a pin placed on the arm pivot. Yes, of course you can eyeball it fairly close, but when you’re dealing with the distances we are talking about, even a mm or 2 could negate the accuracy of the alignment significantly. The same thing is true of many other gauges. The Basis gauge requires you align the tonearm with two lines on the plastic gauge. Can this ever be done with accuracy to 1 mm? So, IMO at least, unless you can be sure about the pivot point, perhaps only the Mint and its like can give you the highest level of accuracy. Of course to some or to many, including myself, I just try my best to get it right with the alignment gauge I have and leave it there. But anyone buying the Smartractor is obviously looking for the most accurate alignment humanly possible.
@chayro There is a little trick you can use on many arms. Take a fine point sharpi and place the tip on the point where you think the axis is. While holding it there move the tonearm over the spindle. If you are right on the mark you will have just a dot left. If you are off the Sharpi will draw a semicircle which will point to where the axis is. Now repeat the process till you are left with just a dot. 
Fortunately for me the Schroder arm has a dimple to aim at. 
In studying the various alignments it does not take much to be way off in either overhang or offset angle. Getting it right using a cardboard over hang gauge is a matter of luck and the weather. The DB Systems Protractor gets you a little closer but the SMARTractor gets you reliably as close as you can get. Eventually I am going to record files of the various alignments and one purposely way out to see what the sonic differences are.
