Upgrade path question with $2k to spend


I'd like to make my next upgrade in my 2 channel signal path. Right now it goes

Ortofon 2M Bronze (cart) -> Pro-Ject Debut Carbon SB (table) -> Pro-Ject Phonobox DS+ (Pre-amp) -> Yamaha Avantage RX-2070 (amp) -> Focal Aria 936 (fronts) + HSU ULS-15 MK2 (sub)

I understand room treatment can give the best bang but lets count that out for now. From a purely component perspective what do you think I should upgrade? Im leaning towards the turntable. It was my first table and altough I upgraded the cart, its only a $500 table. I was thinking of maybe buying the Rega Planar 6 w/ Aria MC cart.

Suggestions welcome thanks!

Please excuse my question as a newbie. I assume that the Yamaha Aventage RX-2070 (amp) also handles quad Blu-ray.  I am in the same situation. If the amp is replaced with a dedicated two-channel, how would access to the quadraphonic sound of those music Blu-rays, which seem to be proliferating (Chicago, Pink Floyd, Beatles, etc.), be accessed?  Thank you for your consideration.

I have 7.1 so I'll be keeping the Yammy for HT.  I'm thinking of external amp with HT bypass being fed by a miniDSP so I can get Dirac Live (I need major correction in my room and can't treat it)

 

Was seeing good things about the Peachtree

@davedword short answer is if you replace your AVR with 2-channel, you can only play back 2 channels (L-R stereo) of a multi-channel recording.  Consider though that most multi-channel audio releases also include 2-channel stereo.  Frankly, most of the re-channeling of old releases isn't all that great (unless we're talking Pink Floyd), and you'll get more enjoyment out of a great 2-channel system with millions of available recordings than mediocre multi-channel with only a limited amount of available source material.

@icegeek , this one is easy. Get a second sub and  proper 2 way crossover. This will get your system stompin for sure. Everything else in the chain is minor in comparison. It is always at the back end of the system that improvements are most noticeable. If you pull 80 to 100 Hz away from your focals you will lower distortion and increase your headroom as much as 10 dB. That is twice as loud. Clipping will be much less common. You ALWAYS need two or more subwoofers. It takes at least two to smooth out room irregularities but the more the merrier. The bass in the room will be more even and powerful. 

Forget the amp for now. You want the bass out of those Arias. The result will be even better. You would need an amp 8 times as powerful to get the same result. We are also not talking about just volume but clean volume. When your system can play at higher intermediate volumes (90 dB) super cleanly the experience is a lot more like being there.
