New Air Tight PC-7 Cartridge...a contender??

I've heard the 7000, not in the same class of the Air Tight PC-7. For the cost, I don't know of a better MC cartridge that I've heard. 

@jeff1225 : From your first post I think that the issue could be that the PC-7 is a better match to your system and your sound priorities. I respect a lot the work of My Sonic Labs.

My Shelter suggestion was because you posted about the 901 as alternative, that's all well it's not because I listened the 7000 and 9000 and are way better performers that the 901 or 90X I owned.

Shelter 901 "not up to today's performance levels" ? :-)))

It's not a computer, it's a cartridge.  Good sound doesn't go obsolete.

Going by your theory, the Grace F-9 Ruby or the clearaudio Insider are also not up to today's standards - because they're old?  You don't notice that today every cartridge is going for more and more detail, and more and more high frequency extension?  Today, even (the used to be soft sounding) Sumiko, Goldring and LINN cartridges sound bright.  You like this  kind of "progress" ??.....

Today's "standard" is garbage.
