What to add or change for my system?


This is my first post, so please have pity on me if I break any rules.... :)

I immersed myself in this hobby a few years ago, and I'm completely hooked.  And best of all, my wife is.....almost hooked.  I initially purchased speakers from Axiom, OPPO 103D from OPPO, and Parasound preamp and amp from a local dealer.  These were connected with Kimber Timbre cables.  I also have a Furman Elite power conditioner.

All of that changed in December.  My system now consists of:
  • Martin Logan Summit X speakers; purcahsed new on AG
  • Plinius Hautonga integrated amp; purcahsed on AG
  • Oppo 105 that has been modded by Tweak Audio for even better audio; purchased on AG
  • Bryston BDP-1; purcahsed on AG
  • Gustard X20 DAC that has been modded by Tweak Audio; purcahsed on AG
  • Gustard U12 USB interface; purchsed new on Amazon
  • Clear Day silver speaker cables; direct from Paul, a wonderful person!
  • Avanti Audio interconnects; direct from Avanti
  • Furman Elite power conditioner; Audioadvisor

As luck would have it, I just got a nice bonus and feel the itch to add to, or make better my system.  Not knowing what to consider, I'm hopeful to get some suggestions from you.  If this was your system, and you had $3-4 thousand to spend, what you add or replace?

Thanks for your thoughts!!!

Thanks djohnson54, sounds like good advice.  The one thing I will do is take a look at room treatment.  With the ML being dipole, I do think I'll get some improvement.  I had not even considered that.

I will get these ordered and then report back.  I promise!

Thanks everyone!  You guys are great!
I'll vote with djohnson54...kick back for awhile and get used to your system.  Play Everything you've got at least 2~3X, esp. the selections you're well-acquainted with.  Fool around with speaker placement...see if anything stands out as an issue.  Do some simple room treatments if that seems likely.

Just because you've got 'the itch' doesn't mean you've got to scratch it. ;)
Besides, you can have the luxury of shopping about at your leisure for the 'next great thing'.  Enjoy....*G*
Other posters have already said it, but to add some weight to their words, three worthwhile considerations are room treatments, isolation feet (vibrapods and support cones worked wonders for me), and a Hubbell cryo'd receptacle all made remarkable differences in the fine tuning of my setup. 

With room treatments, it can be easy to spot what's add if a friend can help. All they have to do is hold a fuzzy fleece blanket in different parts of the room while you listen. You should be able to pinpoint which areas are reflecting sound the most and add treatment there. 

What are the dimensions of the room in question? How far apart are the speakers, and how far are you from them?
Welcome! smills59-

kick back and enjoy the music and your system for awhile. There is plenty of time to change out gear.  Before you do, consider, auditioning cabling (most important).

Happy Listening!
Do you have dedicated AC breakers and lines, going to your system/listening room’s outlets? I wasn’t so much surprised, as I was delighted, when I installed a couple runs of 10 AWG Romex(twisted together) to mine. And YES: room treatments/cabling!
