You have no idea what you are talking about and your statements are boarding stupidity land.
Again, after LP cartridge is the most important item in the analog rig.
You might try it.
I discovered that the arm is more important when one channel of my Transfiguation failed and I had to send it back. While it was gone I needed something to play, and the only thing around at the time was a Grado Green new in the box. Since the Triplanar is so adjustable it was a cinch to set it up right- I was only setting it up so I could play something but its so easy to do I spent the time to be precise; but still I was unprepared for what happened next.
And that was that the Grado was perfectly able to easily track anything I threw at it. This was a bit of a surprise as a $35.00 cartridge shouldn't have been able to do that according to my beliefs at the time. It was a bit forward sounding but then I remembered how important loading is for high output cartridges, so I set it up with a 10K resistor on the cartridge loading strip on the back of my preamp, and then it was just as relaxed and detailed as my Tranfiguration. There was no torture track it didn't handle with great ease. The real difference between the two was that it obviously had more output.
Since then I've seen this simple fact play out again and again. Now we all know that if a cartridge isn't set up right it can have more distortion- and this is easily measured. And we also know that some arms simply won't allow you to set up a cartridge correctly as some of the adjustments needed to dial it in simply don't exist. So its not stupid- in fact I am suggesting quite the opposite: if you can't set up the cartridge properly you are leaving performance on the table! This should be really obvious to any audiophile...
Now this is something that I have no surprise that I might get pushback for; the last thing you want to hear if you spent top dollar on a cartridge is finding out a few hundred dollars at the most may have served just as well, but keep in mind that a Triplanar is a $5500.00 instrument and not everyone has one. Some people might say 'well what about loading on that moving coil' and of course I've answered that many times (look elsewhere on this forum); its simply not a variable.
One other thing- obviously people if they are thinking about this might be curious what I'm running now and at home its still the Transfiguration. This is for several reasons- the first is that it sounds just fine so I'm not motivated to cause my hand to move and replace it with something less expensive just because I can. The second is the Transfiguration has held up surprisingly well over the last ten years and to my knowledge, most MM cartridges would have had the suspension of the cantilever fail at least twice in that time. Finally, as a manufacturer if I have a client come to my home, I don't have to explain to them the reasoning behind an inexpensive cartridge- this last bit due to a phenomena known as the Veblen Effect
