Dear @djfst : I'm not trying to "" questioning/blame "" you but to understand what you posted in your thread if you have an explanation for:
""""
a sound that is not overly detailed, but smooth through entire range, warmer side of neutral, wonderful midrange, and not overly dynamic, lively, detailed where listening fatigue can set in. """"
those are your needs/targets.
Now, normally we build and upgrade ( through the time. ) our audio system to really enjoy MUSIC and your targets goes against MUSIC against how live music performs:
live MUSIC transmit feelings/emotions because its " power " and " dynamics " that almost every audiophile wants even at home but can't do it, well at least we want to be as nearest as we can. " Lively " is the name of the MUSIC.
live MUSIC is everything you want but smooth or warmer if we are listening it at 5-10 m., of course that if we are seated at 30-50 m. from the live source well....
live MUSIC could produce " fatigue " because its SPL.
Now and talkink on top/decent cartridges and listening audio system at " normal " home SPL: if through the listening time we feel " fatigue " is not because the cartridge but because the audio system overall performance, something wrong with that system not the cartridge.
Btw, the stringreen advise on the Windfels is really good advise.
Regards and enjoy the music,
R.
