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

He asked for thoughts/suggestions..

Yes you are right. He only rambling on about components and gear.. And I felt that he is missing the greatest one of them all as I wrote. Just trying to help regarding what is the lowest hanging fruit to achieve better sound quality.

Great we are at the same page. :)

My journey in my dedicated symmetrical 2ch listening room. I got some treatment but far from enough. Even then I had that peek in that room at 73 dB still after many, many different listening positions and speaker placements. 

What I could do is to sound treat and target that 73 hz with Helmholtz or membrane absorbers that need to be tuned to 73 hz..

As we know a DSP will easily take down a peek. 

So best bang (sound quality) for the buck.
The Helmholtz or membrane vs DSP:
DSP will "treat" all frequencies not just one.
DSP will be cheaper
DSP will hit that target issue with greater precision.
DSP can give me 6/12/24/48 dB x-over between my sub and bookshelf speakers.
DSP can compensate for our physical hearing capability (Equal-loudness contour) + "house curves"
And so on..

So it were a no brainier for me to go with the DSP.

And I can now enjoy my HiFi even more with better sound quality despite that I have "degraded" the analog signal with a AD and DA conversion. :)
