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

You're in the dreaded "it's good, but what's better?" zone.

Endless advice from A-Z. Consider just  playing  clean records and open a beer.
Replace your cartridge when it wears with something different.

When you hear a REALLY good system, you realize just about everything needs to be upgraded.
@tablejockey 👍 totally agree. I think my best bet at this point is to look into finding a cartridge that’s more compliant with my tonearm. Not sure how long the Hana SL will last. Will I hear an audible difference and know?  I’ve had It for about a year and listen on average an hour a day. So I have 300-400 hours of wear on it now. Still sounds amazing!
mijostyn. It is good that you like your setup regime of SRA. There is always room for improvements.

For me is that a suboptimal procedure and explains why you do not put that much care in my opinion to it that it may deserve.

Don't get me wrong I also have a USB microscope laying around. The SRA regime you use I call it for the Michael Fremer method.

I am more in the Peter Ledermann camp of method. There we adjust the SRA during when the record is playing. There is a difference between when like Michael F put down the stylus at stand still in stasis.
If you adjust to 92° at stand still and then when you are done, play a record that will put friction and grove modulation on the stylus then you will no longer have 92°.

The dynamic adjustment that Peter L is using is then to do the final fine adjustments by ear.
Now there will a micrometer precision instrument come handy when adjusting the tone arm height on the fly, while you play the record. There is information online on what to listen after and what albums and track to use.

During my years of study how the best do their setups I have learned that there is usually several ways how to go about for adjusting each setting/parameter on a TT.  
So that is why I believe that making sure that the stylus is in the groove with all the parameters as close to ideal is more important for sound quality then what tone arm it is. If the angles between the stylus and grove is little bit more "off". The tone arm cannot compensate for that.

And yes the ideal SRA is changing with different records but the ball is on the playing field and not somewhere in the arena. And on the other hand that is then easily adjusted if we want/needed.
Other than room, it depends on what you want. If you want accurate, uncolored, very detailed sound, a Rega P8 or P10 would be a great option, more for the arms they provide. Cool dustcover that doesn't present any problems. Cartridge that goes for the same accuracy -  Van den hul One Special. (assuming your phono stage goes to 100-200 ohms). It's higher output MC - about .75.

Since vinyl is what you are looking for, the source is key. You can never get better sound than what comes out of the preamp. 
Three things Optimize. 1st is I adjust SRA with the platter turning so it is a true 92 degrees. 2nd is every record is a little different by perhaps give or take 10 minutes. So, if you adjust it by whatever method to one record you will be off on many of them. Third is your ear is nowhere near sensitive enough to pick up 10 minutes of error. You can not even hear 20 minutes.  92 degrees is all you need. Just make the oncoming face of the stylus 90 degrees to the record surface and you are in business.
