START OF LECTURE...
This is a big part of my unhappiness with our Audio community. Very few of us take Pinoy innovators seriously but instead some "gurus" try to sound ever-so-smart by trying to put them down. I have had talks with many who are in my opinion knowledgeable members who simply refuse to post their ideas because of Pinoy prejudice and Kamikaze "guru" attacks. I know how they feel! I had thought long before posting this thread exactly because of this but decided to do so in the hope that a few will be encouraged to do their own little experimenting.
END OF LECTURE.
"From Harry Weisfeld at VPI comes yet another rather simple method, requiring only a mono record and a pair of ears. He suggests that a simple mono recording of voice should provide a stable, non-wavering image, precisely centered between the two speakers. Adjust the azimuth to achieve optimum results. This method works well if you’re practiced enough to know what to listen for, though most listeners would be better served by using one of the tests outlined previously."

I call this the Dante method. Problem solved!

Glad you brought up those methods (At least I'm not the only one that uses the bubble level method ). I did use the polished metal plate before but the problem is that easily gets attracted to the magnet. I replaced this with a polished aluminium plate.

What I've witnessed so far has been an honest to goodness sharing of views which is healthy at the very least. Neither did I see any so called 'kamikaze gurus' as earlier suggested (not in this thread anyway). I should commend Master Mandy for starting this thread. His invitation for us to join in the discussion was gladly accepted by even those who have 'little knowledge', but shared them anyway. But however little they shared has nonetheless enriched WS knowledge data bank, I sincerely believe. I tip my hat's off to Master Mandy Maybe I should reiterate his invitation to everyone; there's nothing to fear, the water is fine.

The online oscilloscope program is quite a revelation. And very interesting too. Hope you can guide us through as some of us are very interested to know where to download it and how to use it.
You mentioned that your 'measured crosstalks are 29.82 and 31.40 mV. Good enough for me.'
What would the absolute values be? Like is there such a thing as perfectly 'matched crosstalk'? Like 31.0 and 31.0mv for both channels? And how much is the tolerance to be able to say that 'that is good for me'? Also, can it happen that the measurements are 'good' but the image is off center, assuming nothing else is wrong in the audio chain? Thanks for sharing.

Remus wrote:As mentioned in my post, I only applied the oscilloscope-crosstalk method to check my set-up which has been previously set using the mirror method. Being "good enough for me" means that what I heard is already acceptable to my standard. The magnitude of the crosstalk really depends on the cartridge. Theoritically, it is possible to attain "azimuth perfection" but this depends on the headshell/tonearm mechanism if it allows micro-adjustment of the azimuth, and of course . . . . one's patience.
