RE: V15-III Stylus Recomendations




I'm familiar with the zevaudio web page you mention...
Although the LZS is classed as a low impedance cartridge, the inductance is sufficiently "high" at 1mH that the electrical bandwidth is very limited with a 100 ohm load. The cutoff occurs at 15.9 kHz. This is possibly intentional given that the mechanical resonance for the MM cartridge is probably in the mid to high 20's (kHz) with a high Q. Normal MCs designed to work into 100 ohms have an inductance that is of the order of 10s of uH (i.e. 3 orders of magnitude smaller) so the electrical bandwidth is of the order of 1+ MHz. Bumping up the load to 2k for example gives a bandwidth of 318kHz with the LZS which flattens out the passband, but of course allows the mechanical resonance to be passed through untamed. This is of little consequence since the resonance is at ultrasonic frequencies and shouldn't cause problems with good ancilliary equipment. With LO MC, the frequency response is unaffected by an increase in load unless one is using a transformer in which case the impedance needs to be matched accordingly.

As for FR of the SAS, it is not as flat above 10kHz as the stock stylus. With a 47k, 200pF load, I get a ruler flat response from 10 to 20kHz with the stock stylus (combined with the pseudo pink noise-like response from 1 to 10kHz). The SAS has a hump at 14.5kHz with the same load. Subjectively many people prefer the "brighter" response from the SAS. Personally it doesn't bother me as I digitally equalise my recordings...but I prefer the SAS because of the superior tracing ability of the SAS profile and the superior alignment to the stock stylus! Shure have acquired Stanton's disease and can't seem to align the cantilever so that the stylus is perpendicular anymore....
