I have joined in the ZYX Family


Funny how change comes about. I’ve been intending to get a tube preamp for years 10-12 years. Instead, I got a tube amp which sounds great. . Tube amp with SS preamp sounds GREAT. FWIW, the SS Preamp was a Stereophile Class A Conrad Johnson PFR. So, its not like I was shooting in the dark. The PFR is a really good preamp. And the Bob Latino ST-70 seems to be a great fit along with the Silverline Sonatas. So I set out to get my turntable up to its optimum. I have a Teres 340 which has an Origin Live Illustrious 3 with Benz Ebony L cartridge. I put the OL Illustrious on it as a temporary arm. I figured the Teres deserved much better. But Maybe I am wrong. It sounds great. However, being an audiophile, I can’t leave it alone. So I set out to get a new tonearm worthy of the Teres 340. But then someone reminds me that a cartridge will make more difference than a tonearm upgrade, especially since the tonearm is a pretty good one. . So I consider the idea and come across a ZYX 4D for a good price. Thank you Raulirigueus(sp) for the idea. In the process, I saved some $$$ too. I’ve wanted a ZYX for quite some time. NOW, I see what all the fuss is about. This cartridge is fabulous. Next up is to clean the electric. Oneac seems to be a good way to go. But, who knows. My plans often go sideways. But I’ve really made some big steps forward thanks to some good advice and the good Lord above who over rules my ignorance. FWIW I often pity those who miss the beauty of good music. I love it. Thanks for your help along the way.

The ZYX 4D internal impedance is 4 ohm and MC cartridges with such a low (or even lower) impedance is not sensitive to loading. How would you all comment this statement?

ZYX own top of the line headamp designed by Nakatsuka-San for his cartridges is 125 ohm (fixed).

Recommendation for loading is just "higher than 100ohms".
Chakster, I can only tell you what I heard. I was happy with 100 ohm loading. But since the recommendation was higher than 100, I tried the 470. My post above notes my observation
Chakster:

According to the specifications provided by ZYX, they recommend a load impedance of greater than 100 ohms. Why would ZYX make the recommendation, if in fact as you say the 4D is not sensitive to loading? Hoping you can provide more insight for us uneducated masses. :-)
@thaluza 

well, i can point you on setting of the Nakatsuka-San (ZYX designer) own headamp for his top of the line cartridges. The load impedance on this device is fixed at 125ohm. When a designer build such device for his best cartridges the choosen load impedance (if it's fixed) must be the best match (in his opinion). But users are free to connect MC cartridge even directly to the MM (47k ohm) input, some people like it, and that's why the only limit in the manual is not lower than 100 ohm. 

The statement that low impedance ZYX MC carts are not sensitive to loading was posted here by other users too.  
Hhhmmm..

my ZYX R-1000 Airy 3 SL (4 Ohm) was more sensitive to higher
loads. It had a tendency to harshness when loaded with more than
320 Ohm.

My ZYX 4D XH (8 Ohm) was more flexible and played even with
47 kOhm phantastic.
