P5-xe, codex, XLR interconnects

I have some experience with Ayre.  I’m running all my sources balanced into an Ayre AX5/20, including the Ayre Codex. Before I upgraded to the Ayre AX5/20, I had the Rogue Cronus Magnum 2, which sounded great for the money but was single ended. The Codex sounded significantly better balanced than unbalanced in my opinion (I tried using some expensive RCA cables with little improvement).  I also own the PX5e phono pre-amp, my turntable is running fully balanced (had to change the tonearm cable to run balanced) into the PX5e and fully balanced out of the PX5e into the amp. The PX5e is an excellent phono pre-amp, very very quiet.  My only negative is that every time I want to change from a MM cart to an MC cart, I have open up the box and change the settings from the inside.  It would have been awesome if there was option to change the gain setting without opening the box.  If you’re thinking about Ayre equipment, I highly suggest running fully balanced.  Don’t get me wrong, single ended sounds great too but balanced just sounds better with Ayre. If I were you and I wanted to go with Ayre components to match up with the AX7e, I would buy the Codex and PX5e used and saving up for better cables.  I also think that Tomic601 suggestion is soild. The Treos are fantastic speakers and would bring the most improvement to the sound. Good luck! 

To be fair, I don’t change my cart often. I did change the settings a few times while upgrading to a different cart, a/b comparing a couple different carts, which was a bit of a pain.  I haven’t change the cart in over a year.  It’s not as bad as it sounded, I think most people once they find the cart they like, don’t really change it until the cart wears out.  I do have friends who switch out carts every few months because it a hobby for them to collect different carts.  Considering you listen to mostly digital, i would try the Codex first before buying or trying anything else.
