Dear @wynpalmer4 and friends: Other that your very clear higligths I posted other gentleman posted in this thread:
" If your set up sounds "wrong" with more modest loading, such as 100 ohms, something might be wrong elsewhere..."""
I don't know why all those " huge " inistence on the capacitance LOMC subject maybe because one of them is a seller .
Now, you are a gentleman that already use around " 100 ohms as loading the LOMC cartridge and in the Madake 60 ohms with great results.
I experienced always in the same way however a " live " evaluation tests are in order and as always I just did it because it's the best way to learn something new or confirm our believes.
I have my own fully proccess to make audio items evaluations in my system through listening sessions. My tests evaluation was changing only one parameter that's the cartridge load impedance going from my usual 100 ohms to 47kohms and 100kohms. Fortunatelly I have that proved proccess ( tested in my system and many other diffrenet systems. ) and a truly high resolution and precise system. Well this is what I found out against 100 ohms:
I found out no more transparency or openess in the system presentation in those HF range but what I heard is lower " definition " of the fundamental and developed harmonics even in some of the tracks of that test proccess part of the detalied HF with 100 ohms not only was veiled but just disappeared. The transient and decay time changed in a way that makes everything more " ethereal " than with live music definition.
The overall presentation at 47/100k has a penalty not only in the HF range but even at the lower ranges maybe because the " contrast " in between goes smaller but I can't be sure why.
Taking those Wyn highlighs and the larryi ( now I remember whom posted the highligth at the begin of this post. ) I agree with both of you and what larryi said is true " something wrong " in the system.
Seems to me that some of you that prefer 47K with out intention to do it what in reality are doing is " compensating " some " faults " somewhere in the audio system links of that complex system chain and could be problems in more than one of those system links.
My take is that before we make changes on LOMC cartridge loading and especially from 100 ohms to 47K we have to be totally sure that at every single system link we have no " problems " but if you are unaware of that then you have to make a proved testing evaluation using a proccess that permit a " true " evaluation. Obviously that we can't be absolutely sure of the proccess validity but we have to be nearer to that " true ".
Is more frecuent/often that we make changes where we don't need to do it but anyway we did it and think that were for the better when in reallity are only hidden system " errors " somewhere.
Of course that for those evaluations we have to be honest with our self and not biased on purpose or because we are accustom to this or that characteristic in the sounds and obviously that we have to be sure that we know how sounds each instrument in a near field live event.
Btw, I made my tests as always: at normal seating position and at near field position. As a part of my proccess tests headphones are inside but normally I don't use it because I'm truly engaged with the system but this time I used and confirms what I said. I always prefer the near field test than the headphones because I'm not accustom to.
Btw, I tested through too using an additional full stage with my AU-1000 SUT with similar results that in the active high gain phonolinepreamp.
Now, sounds bad at 47K? no it did not but when you are accustom to the top quality level I'm the you can listen the difference at once not 3 hours latter, it's immediatly.
