Ortofon Per Windfeld Load Impedance?


I'm curious to hear what load impedance other PW owners are using for this cartridge. My manual recommends > 10 kOhms which I suspect is a print error. I notice that the dealer sites are recommending >10 Ohms.

A good rule of thumb (i.e. place to start) is 25 times the coil resistance of the cartridge. That generally winds up somewhere between 100 - 1000 ohms as most moving coils have an internal resistance between 4 and 40 ohms. Then you can vary it up or down 50% (from the 25 times number) until you get the best results.

I have both the Jubilee and Windfeld here and in 5 different phono stages including Manley Steelhead, Art Audio Vinyl Reference, Atma Sphere MP-1 (phono version), and Oracle Temple the ideal loading should lie between 125 and 175 ohms.

Pay no attention to the first post's obvious lack of experience.

Zieman,
I don't want to embarrass you further but the impedance of any phono cable is negligible. I'm sure you don't know this based on your posts.

Most phono cables have impedances of well under 2 ohms; some are as low as 0.15 ohms (Zu Xaus).

The only time the phono cable impedance comes into play is when it's value exceeds the internal impedance of the cartridge. Which is seldom and never.

The bottom line is to ignore phono cable impedance.

Check this out with any cartridge, phono stage, or cable designer. I hope you learn something from this.

Now the question is, how do you fit both hands in your mouth where both feet seem to reside frequently.
Thanks Ralph,
You've validated my position concerning irrelevance of the phono cable as it relates to cartridge loading.

This is Vinyl 101 and I hope others pay attention.
>>As you will know the car performs much better the lighter it is<<

That's a bad analogy. The car may accelerate faster but not handle as well without proper weight and weight distribution.

I hope Ralph addresses the other technical errors and misunderstandings in your post.
Everything I've said is correct Zbag.

OTOH, you've been wrong consistently as pointed out by Ralph, Raul, Jonathan, Tvad, me, and every knowledgable person.

However, you seem to excel at casting aspersions, name calling, and insults in general. Those seem to be your strengths as you consistently duck the issues at hand and divert attention from your lack of understanding with snide remarks and worthless posts.

How's that white paper coming along?
Another obtuse response Z and devoid of contributory value.

You've not addressed any of the issues.

Again.

Raul knows the material well in discussion here. As I do. As Ralph does. If that's "2 (or 3) peas in a pod" I consider it a compliment.

How's that white paper coming along?
