Recommended a highly resolving cartridge


Hi all, all tube system that is warm with a good midrange presence inherently. I’m looking for a cartridge that offers high detail / resolution and wide / deep soundstage. This is on a stock SL-1200G TT. On a side note, if anyone has experience “upgrading” the stock tonearm on a G please chime in. I’ve read conflicting reports of the merits of such a move, and while I’m very happy with the tone of my TT and am not looking to move off of it, I am curious about a tonearm swap (must allow for headshell swapping).

I have my ART20 installed in my second home system where it does sound quite good to me.  Unfortunately I have no frame of reference for comparison.  It is installed in an SME 3009 Series II, which was rebuilt last year by SME Canada.  TT is my old HW19 MKIII that I have had since new.  While the system is quite enjoyable, it does not really stand comparison with my main system.  All these favorable comments force me to consider taking the ART20 with me when I return south for the winter so I can more fully understand it.  

Wow, loud for me is 80 - 85db. I am thankful when I was in my 20's my quest for 115db did not damage my hearing. 

Peaks at 113.1db are quite different than average volume at 113.1db! As per the meter the average volume was at 87.5. Yes there may have been a gummy + beers + an empty (no wife) house as factors too.
