Clearaudio Azimuth Optimizer V Fozgometer


I have been through a few threads regarding the Fozgometer for Azimuth adjustment .Has anyone used the Clearaudio Azimuth Optimizer which cost quite a bit more then the Fozgometer and if so how did it go!!

Don, You seem to assume that "correct" azimuth is always equal to the condition where the top surface of the cartridge body is parallel to the LP surface. Not so. Your bubble level will only be "right" for some cartridges; most are not perfectly constructed so that all the innards are oriented as you'd expect.

By the way, the bubble level must add a hell of a lot of effective mass to the tonearm. What does it weigh?
Don and Bif, There were so many reports on this forum of odd results with the Fozgometer that I have never purchased one or even tried one out in my system. I am sure that some of those reported problems were due to misapplication of the instrument, but nevertheless, the seeds of doubt were sewn. I own an ancient Signet Cartridge Analyzer, and that's what I've used to set azimuth. The advantage of the Signet (I think) vs the Foz is that it takes the output of the cartridge directly, not via the output of the phono stage. So, errors due to imbalance in phono channels are avoided. The bad news is that the Signet does not have sufficient gain by itself to work well with LOMC cartridges. I have been meaning to build in an extra gain stage or to have Bill Thalmann do it. But the kicker is that I only bother to use the Signet with my Triplanar and my Reed tonearms, because only those two have decent mechanisms for azimuth adjust. With my other tonearms (mainly the Dynavector DV505), I just go with "parallel to the LP surface", realizing that this criterion is not always the best. I guess you could say that I've given up the ghost. To some degree, I side with Nils.

I am most tempted by the Feickert program, because I have a laptop that does not get much use. The Clearaudio is just plain ridiculous, based on cost alone. How much better could it possibly be than either the Feickert or the Foz? My response would be "not that much, if at all". The dark horse would be the device that Soundsmith was perfecting, last I knew. Supposedly it would read out a variety of cartridge characteristics and also provide for azimuth setting. What happened to that? Is it for sale?
