In Reply to: RE: Anyone after a Stanton 980LZS... posted by flood2 on October 15, 2014 at 02:35:57
Hi flood2
I have the 981LZS (bought new) and saw a HZS on eBay but without a stylus. Figured I'd swap the LZS stylus between the two but when I read Richards manual on the Stantons and then realized that PickeringUK.com had stock of the 3500E I grabbed one. Wish I grabbed two!

Lucky you!! How do you compare the sound of the LZS to the HZS? The LZS is my favourite cartridge (for MM). I found the LZS requires a much higher load than the 100ohms specified. I settled on > 2kohm. At the recommended load, there is a very pronounced roll off above 10kHz giving a minimum of nearly 5dB at 18kHz before the tip resonance kicks in. At the higher load, the frequency response is much flatter with about a 2dB dip at 18kHz.
Once corrected, the sound is very neutral with a wide soundstage combined with the amazing tracking ability.

Hello flood2
Of the two, if I use the same stylus on both of them, I lean towards the HZS as a preference. It just might be from lack of doing various loading trials as you have done. But it is so close that I just leave the D98 stylus on the LZS and run the 3500E on the HZS. I do load the LZS at 1000 ohms. The HZS gets run at 100K Ohms resistance and no added capacitance. I have measured capacitance from the input lead of the tone arm to the input of the phono stage. My current capacitance reading for the system is 168 . I at one time had this reading as high as 312. And that was back when I would "add" the recommended capacitance that the cartridge manual stated. But after several cable changes and mainly their lengths shortened, I now have it down to the 168. You can really tell the difference when using M/M cartridges. If you have never done this check, I think you will be in for quite a surprise at the amount of unknown capacitance that gets applied to M/M cartridges. I use the Elenco Capacitance meter. I did a internet search and found one for $35 approx. Money well spent!

Ahh, just the answer I was hoping for! The electrical resonance for the HZS is positioned right where the "dip" (around 16 to 18kHz) that I measure with the LZS occurs. I always wondered if the HZS was the "correct" match and the LZS more of a "hack" to achieve a unique design.
I presume by zero capacitance you mean nothing added in the phono stage - you will still have capacitiance in the tonearm wires, headshell leads and phono lead. Depending on length, the phono lead is going to be at least 90pF, the tonearm wires roughly another 10pF so you have at least 100pF. This would shift the electrical resonance from about 17kHz to ~24kHz.
Yes, I have a capacitance meter as well (I'm an EE! :) )
I don't believe that it is necessary to deviate significantly from the recommended values - the electrical resonance frequency has to be matched to the mechanical properties of the moving system and so any significant deviation in resistance and capacitance from the nominal would indicate a fault in manufacture or in the replay system somewhere - possibly even the phono stage EQ. It is incredible that even today mistakes are still made in the EQ on commercial designs.
However, I agree with you that even small changes in capacitance can be enough to make a subtle improvement with MM.
BTW, do you still have the original paperwork etc for the LZS? I was wondering if you would you be able to scan the frequency response chart and the spec section of the instruction manual and PM me? Very often design changes magically appear in the specs but aren't documented anywhere else! I'm curious to see the characteristic measured for your LZS to see how it compares to my D88S and D4500S.
Would be much appreciated thanks! :)
