Technics SL1210GAE + Accuphase E-480 (AD-50) + ??? (cartridge)

Looking for some great cartridge options for the Technics SL1210GAE (stock) and the Accuphase E-480 with the AD-50 phonostage.  The challenge I see is that many options like the Kiseki Purpleheart seems to want higher loading than the AD-50 is capable of (300ohms, max).  I'm looking to spend up to $4000 for a cartridge that sounds amazing.  Using Magico S5 MkII speakers.

I like authoritative bass, but a really airy midrange and treble that has a clear "ease" to it.  I like my midrange "painted" in front of me instead of coming at me.  I had heard the Purpleheart was great that way, but I'd prefer not to get into separate phonostages for a second system, hence the use of the AD-50.
@jdal Thank you for the suggestion!  Which headshell are you using?  Did you have to shim for VTA?  Any other setup issues?

@rauliruegas I see there are now two different ART-9 carts.  Is there a reason the XA is best for this setup?

@chakster I have heard of the ART1000, why do you like this cartridge?  Have you used it with technics G/GAE?

@lalitk Curious as to what settings you're using with the AD-50 and Umami Red.  Were there other carts you compared?
ART-1000 is unique design, not a conventional MC, I already mentionad why, this design was invented by Victor in Japan in the 70’s (called Direct Couple type). AT improved and upgraded this design. Read about it, watch Fremer’s video tour at Audio-Technica in Japan. 
I prefer Technics EPA-100 mk2 tonearm over new arm you have on G or GAE series, but it doesn’t matter, with stock arm you can use hundreds of cartridges, no matter what other people are using. Any mid compliance cart is a perfect match! 
I tried over 60 cartridges on various Technics tonearms and turntables. 
No one can tell you what cartridge to use, because you can use so many and this arm is very easy to adjust. Stock headshell is fine, if you want to try different shells you can buy 15 more headshells of different mass to experiment with, no one can tell you what you need as the weight of the shell can change tonearm mass and you have to calculate it according to cartridge weight and cartridge compliance. 


I am using 300ohms settings with Hana Red in AD-50. I have tried 100ohms as well but to my ears 300ohms loading sounded the best. Hana suggested loading is >60ohms. 
The other cart I’ve tried is Hana M (MC) which prompted me to step up to Red. 
Dear @tre9901  :  The ART 9XA is descendent from the heavy acclaimed ART 7 that has a very important design characteristic that no others AT cartridges have and is:  non-magnetic core.

""  Compared with the magnetic core used in most MC cartridges, non-magnetic core cartridges are free from magnetic distortion, allowing for natural timbre and a precise sound field.  "" and it makes a difference for the better.

The other critical important characteristic is that's a lower output design that the other AT models. The XA comes with a 0.2mV output level that means it has less wire at its coils, so the cartridge signal suffers less degradation than cartridges with 0.3 or 0.4mVs.Btw, it will mates very well with your tonearm that's really good one but even its high quality of that Technics gear you own you can improve it using these headshell wires that are an important and crucial link for the cartridge signal ( again ) suffers the lowest degradation down there. At the end what we audiophiles should be is try to preserves the cartridge signal integrity because is there where comes all the sound that we will listen at our room/system seat position. Those headshell wires is a must to change. Here an excellent alternative about:

Obviously that you can buy additional headshells with better performance than the stock one. You can but wood material build headshell or magnesium or blended magnesium and the like. A different headshell makes a difference too for the better or bad depends on our choices about.

Finally could be a good idea ( latter on. ) to re-wire the tonearm internal wires for something a little better and here too you will hear a high differences for the better. With those changes your Technics gear will goes to another levels and you could say it belongs to the big league. Here the tonearm re-wire:

Btw, the VTA mechanism in your tonearm is by a wide margin the best VTA mechanis ever builded, period. It comes from the vintage Technics EPA 500 and today not yet outperfomed, I love it.

Regards and enjoy the MUSIC NOT DISTORTIONS,

I do not have direct experience with the Accuphase AD-50 phono, so my comments come from general experience:
 I would hesitate to jump into a 0.2mV cart unless user experience strongly suggests the phono is up to it. That's quite a low output and generally requires excellence from the phono...For a lomc it is possible that splitting the budget between cart and SUT and then using the MM input *may* yield better results. I am not a 'SUT all the time' person btw...

Oh and the Sculpture A carts and SUT are both worth a look in addition to the other good suggestions above.

Caveat: I am in the trade and have a relationship with Sculpture A.
