Dear @dsjs4 : Yes that Clearaudio is made by AT under Clearaudio specs not under AT ones and yes it has not owner stylus replacement and this is far away to be a disadvantage but the other way around:
in any stylus replacement cartridge design the whole part that hold the cantilever/stylus is way resonant against the cartridge with no moving replacement stylus part. So you can have higher cartridge signal degradation with that with the fixed design.
One of the best cartridges in the past were the B&O MMC 1/2 great MI performers that had fixed stylus design, was not at random designers decision.
Repeat, it's an advantage and is a characteristic that shares with LOMC designs.
I like Nagaoka too but looking to your audio system items my vote still goes for Clearaudio.
