Lyra Atlas experiences
The SMEV is a great arm, but not for a cartridge like the Atlas. The compliance is ~ 12x10 cm/dyne bei 100 Hz You need a heavier arm to get best results. I had a Kleos in an Origin Live Conqueror with 18gramm eff. mass and in a Reed 3P with the same mass. The SMEV is a great combination with Van den Hull cartridges. |
The simplest way to check the anti-skate is by ''tracking abiity'' test on the test records. The first distortion will appear in the right channel. By increasing the anti-skate force the mentioned distortion will disappear. So much about the causal relation. However one should not try to get those 80-90 microns ''pure'' because to much anti-skate is worse than no skate at all. |
Heavier arm - perhaps - I think J Carr wrote that it is possible to tweak the mass of the arm. I thought the SME V would be an OK match. I’ve tried some more mass (damping material) on the headshell and the arm but it didn’t work for me (not even some ’magic dots’ I had). I did some eyeballing tests now, using a loupe and then some 20x glasses. Stylus settles as before, a little to the right, in the hole in the front. Mirror test; it looks vertical. I had to turn down the AS to 1.1 to avoid the arm sliding to the right (the platter is level). I wanted to have a look at the stylus tip also, but the glasses are too weak. So I tried a little 100x microscope with light. I got nervous, however, it has to go extremely close the cantilever. Perhaps later I will try a small USB microscope that I also have. But well, so far, there is no visible sign that the azimuth is off. So it should be an OK starting point for listening tests. |
All theory, after repairing in Japan my Kleos had a very high compliance and my bass speakers made synchron movements to the out of center vinyl. https://www.youtube.com/watch?v=R1yvgCINtI4 |
