Dedicated Vinyl system next upgrade?


Hi. I love my system. I really do. I love vinyl and listen to vinyl nearly exclusively via “appointment listening”. I do Sometimes stream and listen while I walk or while working but I love just sitting and listening to my stereo. I believe I’ve arrived regarding finally achieving a great set up and have experienced that vinyl “magic” that audiophiles obsess over. I understand that limitations exist and a great stereo will reveal the quality of a recording - good or bad. The law a diminishing returns regarding  upgrading is something I’m mindful of. I don’t have endless funds to spend on upgrades. My question is - what should I consider upgrading next? Should I ditch the integrated amp considering I’m using an external phono stage? Or should I go with a better integrated amp? Or should I look at a better cartridge? Do I upgrade my turntable or just the tonearm? Do I upgrade the power cable on my amp? 
Here’s what I’m currently working with - and thanks for your thoughts/suggestions! 

Clear Audio Concept Turntable
W/ Hana SL cartridge 

Herron Audio VTPH-2a Phono Stage

Rogue Audio Cronus Magnum II integrated power amplifier 

Kimber Kable speaker wire and interconnects (I forget which model - an entry lever set - nothing crazy) 

Bowers and Wilkins 805 D3 stand mount loud speakers

Set of two stereo REL S/510 subs

@mulveling is a connoisseur of high end cartridges. I suggest that you consider his opinions carefully.

I agree with others about the tonearm, and suggest another possibility, the Trans-Fi Terminator air bearing tonearm. IMO it's better than anything that costs less than the price of a car, and costs under $1500 direct from the manufacturer. I have two of them, one on a $10K conventional turntable, and another on a DIY air bearing special.

The only real function of a tonearm is to hold the cartridge in precise relation to the record. It follows that the tonearm must be highly adjustable and hold its settings. The Trans-Fi does that better than most. And of course, it's an air bearing (actually, air bearing horizontal and knife-edge vertical).

Good luck!
Also what’s a reference disc that brings you great joy but also let’s sonic doubt creep in ? And how loud do you listen to that ? Trying to help by listening 
@tomic601 reference disk Neil Young - After The Gold Rush. I have a few pressings. They all sound great and I don’t know if there’s one singular thing that I doubt. If I had to choose I’d say that I sometimes question the top end. I sometimes feel/hear a brightness that can be off putting or a bit harsh. I’m not sure if this is speaker thing, or a matter of recording or something else? I do know my speakers have a reputation of being of sounding bright. I dunno. Again, there are times when I’m listening and I can’t imagine a better sounding stereo. Then there are other times when I’m slightly annoyed with the top end. The nature of the beast I guess. 
My pressing of that is the reissue Winchester in NM-, I will give that a spin. Thanks for the super detailed reply.

Your system seems top notch. Top end brightness can be somewhat resolved with speaker placement and room treatments in my opinion. It’s the “ghost” in my system as well. I’m in a similar place with my system. Totally satisfied 90% of the time. The only upgrade I have done recently was to send some of my reference Lps out for a proper cleaning. I used www.thevinylarchivist.com as he is local to me. I can’t tell you what an improvement a proper ultrasonic cleaning has done for the LP’s I had done. It’s insane what a difference it has made. Even on seemingly “perfect” pressings I own. Good luck on your journey!
