Upgrade phono stage?


Have an AudioNote M1 phono MM.  It still delivers great music!  I don't know if I should upgrade the phono stage part.  Purchase a stand alone phono stage and run it through the aux inputs?

Chakster, Buried somewhere I still have one of my old Stanton 681EE cartridges brush and all. In it's day it was a great cartridge (brush removed) In no way is it a match for something like the Ortofon 2M Black never mind the Clearaudio MM cartridges or the current crop of Audio Technica cartridges. Some things are better left in the past.
Chakster, u have any MM you would like to part with?  I've looked at a few stand alone phono stages, Decware and Bottlehead....
Chakster, when I asked part with, I was willing to purchase. NVM, I found a couple for sale.  should get them this weekend.  Thanks.
