Diamond Stylus Enters the 4th Dimension

@mijostyn I think you are right, the Acoustat 6 and the model 8 were in fact doubled up three’s and fours. I seem to remember that they were not called 3+3 or 4+4 though. I did think that the stacked Quad’s were more revealing and accurate in their timbre and midrange reproduction.
I could never get my Acoustat 3’s to really sound that great, the Maggie’s that I sold to buy them, where in my system far superior sounding. The Maggie's were just so much more accurate in their bottom end response and imaged with greater precision. At the time i was using a Counterpoint preamp and a Melos tube amp...perhaps that was the issue??

I use the DS Audio ST-50. On my Dynavector Karat 17DX. Is that similar to the Oznow?

Yes daveyf your problem was the amp. They did much better with class A SS amps. They also had to be aimed right at you unlike the Maggies. The bass was never that great. You either needed subwoofers or one of the 8 foot versions to get decent bass. I had Monitor 4's mounted on top of RH 
Labs subwoofers. That was a very potent system The 4's were using Acoustat's high voltage tube amp. But I didn't fall in love with the Acoustats until the 2+2's. A full spectrum line source is a thing to behold.
Everything becomes life size and the projection is much better. I went to Apogee Divas for a while. After 6 years out of frustration I returned to the 2+2's were I have stayed for some 20 odd years. Only the tall Sound Labs speakers are of interest to me. I would not mind a little more horizontal dispersion and efficiency. The other advantage of these speakers is no crossover. They are truly full range although IMHO they do much better when you take the bass away from them. The digital cross over I use can be dialed in perfectly. 

Some time ago J. Carr explained difference bewteen cantilever
materials. The (only?) advantage of aluminum cantilevers is
that stylus can be pressure fitted in. In ''all exotic kinds'' the 
stylus must be glued in. By those one must avoid fluid cleaning
obviously because of fear for disolving the glue. Those who ''know better'' and still use fluid should not complain. 

This is the advice that is given and I only used a dry brush. However the glue they are using is undoubtedly a cross linking resin of some sort like epoxy which once cured will not dissolve in any common solvent. UV can attack it but that takes decades if not centuries.
