Fozgometer?

Does anyone know how this compares to the Feikert azimuth plus?

Ciao,

I purchased a Fozgometer right after CES when the lead time was only a few weeks. The unit is very well made and works prefectly of course you need a test LP, I picked one up that had the correct test tones at a local record store for about $10, I got lucky. I bought the meter specifically for my Clearaudio Reference table with Souther TQ1 Linear arm. I was having a lot of trouble dialing in the cartridge, if you are at all familar with the arm you will understand why. Everything was set correctly but it still did not sound as it right. We played with the azimuth using a level, measure, then eyeballing it, then my friends eyeballed it, all with the same result. Checking the azimuth with the meter confirmed our suspisions, the azimuth was way off. A slight adjustment, then rechecked it with the meter and the azimuth is dead on. What took hours of guesswork was completed in 5 minutes with the Fozgometer meter. The sound of the table is now perfect. I checked the other arm on the table, a Clearaudio Satisfy which has adjustable azimuth but it was dead on as was the arm arms we checked like a Rega 300/301s where there is no adjustment. Good tool to pick up if you need it.

I purchased a Fozgometer several weeks ago, and I have not had much luck with it. The needle jumps around too much to get a good reading. The manual does indicate that this may happen with undamped unipivot tonearms, which is what I have (JMW9 Signature). I suppose I could add damping fluid and try again, but if I'm not planning on using the TT with damping fluid, it seems like a waste of time.

Also, I didn't have the Acoustic Sounds test record. I have the Hi-Fi News test record. The difference is that, instead of a 1khz tone, it has a pink noise tone. I doubt if that would make a difference, though. Either should work.

No, I believe it would make a difference in that with pink noise, and white noise, it would be even more necessary to have a 1kHz notch filter as these distribute power over the spectrum. I would guess that even with a 1kHz test tone on an LP you would still do better with a notch filter because there is noise in a wider frequency band induced by the scratching of the stylus.

General statements, I'm not implying anything towards the Foz-gizmo. I'm guessing it is a DMM with a built in filter?
