MC cartridge loading: still baffled


I am using a low output moving coil cartridge- a retipped Linn Troika.  Recommended loading is 100-200 ohms which I have always followed.  My phono pre is an Ayre P-5xe and set to the highest gain.  Years ago, Michael at Ayre said most moving coil cartridges sounded best when loaded at 47k ohm using their phono pre.  I just got around to trying this setting and it does sound more open and better to me.  Lately, I am discovering that much of the dogma that I have been following isn't necessarily correct, at least with my system and to my ears.  Another example I found recently is that my arm/cartridge performs just fine with very little anti-skate force as opposed to just picking a setting equal to VTF as universally suggested.

Back to the loading question:  is the proper loading more a function of the phono pre or the cartridge itself?

Actually Lewm that is Frank Schroeder's method. I prefer to use the HI Fi News test record as it has an excellent anti skate track and both vertical and lateral resonance tracks. But I have noticed repeatedly that once I set up the tonearm with the record the tonearm drifts slowly towards the spindle on a blank record so Frank's method works. 
When using the test record you are using your ears to detect miss tracking.
I can't count the number of screws millercarbon has loose. Setting up a system is simple once you know what you are doing. The vast majority of "tweaking" is mythology. A really good tech can interpret what a client wants to hear into the system's sound. 
Yogi, blank LP is not a good tool for setting AS. The skating force is due to the friction of the stylus as it passes over the vinyl in the groove. A blank LP by definition has no grooves. Therefore, it does not present the same friction related resistance to travel as does a real LP with grooves. This has been stated and restated over and over again on various forums.
While I agree with your conclusion, the number of falsehoods being stated on various forums as facts are as numerous as the grains of sand on a decently sized beach.
lewn,

The blank disc is NOT intended to simulate actual operating conditions.  From experience of many manufacturers and listeners, it gives a rough approximation of what the correct setting would be when playing actual records.  Like all antiskating measures, at best, one can only get a roughly correct setting--actual skating forces change dynamically during play (tends to be higher at high modulation levels) and this methodology is intended to roughly mimic the forces when playing records at average modulation levels.  I think SoundSmith has a video explaining this approach.  

I use to set antiskating using test records (like the Shure trackability test records) with music played at higher and higher levels and I would set the antiskating at a level that minimizes mis-tracking or cause the mis-tracking to be about equal in both channels, and then I would back off antiskating from this level just a bit to account for the fact that I never have records recorded at such high levels of modulation.  I now just use the blank record approach (much easier).
