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?

Your system sounds really nice.  Best upgrade path I would suggest is to switch to an MC cart.  Add SUT (like Bob's Devices) or active head-amp (like a Piccolo2).  Also try some tube dampers (even simple o-rings can make a difference).  
Thanks, I have thought about MC..but didn't want to change my system.  Your suggestions are an addition to my system sounds good, thanks again.
exact MM cart.

@robertod2a3 I think you'd be better with another cartridge and your Audio Note phono stage. The exact cartridge offered by Rega (by default) to keep the price low. You can find much better MM or MI cartridge from respected cartridge manufacturer, Rega is not a cartridge manufacturer anyway.
