What are the most balanced relatively neutral cartridges at each price level ?

Stringreen,

The least you can do is get the name right.  Ortofon Windfeld.  I agree with you it is a very nice cartridge.  One of the best.

@billstevenson Do you mean to tell me the SME V is not still considered a reference tonearm?  I must be seriously out of touch.  Please define what you mean by reference.

As I've pointed out before, SME gets little love here in the colonies. Rest assured, you have a fine tonearm.

Dogberry,

I believe you are operating under a false assumption although I can understand why.  There are those of us in the colonies who totally understand and respect SME.  I do not own an SME V.  I do own other SME arms, but that was not my question.  Your reply is telling, however.  Wrong headed people apparently believe the SME V is not still considered a reference tonearm.  Never mind that it performs at a reference level that very few can match and in my experience damn few can even approach.  Thank you for your insight.

You don't compare vinyl to digital, you compare it to master tape dubs

Not me, mate.  I know what a full orchestra sounds like in a good acoustic.  That's what I use as a reference.

For level 4, the answer WAS Tranfiguration, now sadly defunct.  The most tonally neutral LOMCs I ever heard. At level 1, Nagaoka MP500 is as good a choice as any other.
