I have just finished setting up my system after a 5 year break (building our next home), I now at last I have a dedicated room for my quadraphonic system.
My gear is a CD4, SQ system exactly as it was circa 1972-1975.
After the last replacement stylus for my jvc Victor X1 cartridge wore out around 15 years ago I have been using a DL160 for normal stereo and occasional playing of CD4 records which it did I thought reasonably well.
Moving on I bought a AT440mlb cartridge after reading the quadfather's recommendations ( this is the first Micro ridge stylus I have ever used I always assumed they were like ordinary line contact types) (not shibata) which never gave success.
The cartridge took several hours to set up as azimuth and stylus rake angle seem critical with this stylus shape and rewired my technics SL110 and got the total wiring and plugs capacitance down to 57 pf.
Finally deoxed the 4dd5 and got my CD4 test record out and started setting the left channel difference control and WOW! the null point just snapped in, virtually zero crosstalk, same on the right channel and after 3-4 clicks on the level pot zero distortion!
This is a great cartridge for CD4 probably better than the Victor X1 ever was, though getting low capacitance cable was always hard back then (no cheap capacitance meters) and most UK HI-FI shops didn't know what capacitance or cartridge loading was.
Finally again
THANK YOU
