PERSONAL GEAR LIST; Your opinion on next best upgrade?

 I purposely didn't want to talk about what I think is weak due to wanting uncolored gear focused opinions. I guess I can say that the system seems to have "plateaued". I am after advice on which piece, if all other things were equal, would be considered the weakest link in the current chain.

Yes, either speakers, room treatments, and/or improving the source material by finding the best masterings.

I think you could get better sounding speakers, not knocking NHT but many, many very good speakers out there...could improve your system.

Thanks.
I should have added a pertinent condition here.
I’d like to spend up to $4000 on the next upgrade. So I suppose the question should have been "given the current gear which link(s) is the next to upgrade with a max budget of 4k?"

Bad, I would like to share another tidbit of info FWIW. I went searching for speakers within 90 miles of my home. I wanted to LISTEN and compare myself. I was advised by a couple of good dealers to bring my own music, to include some music I know very well. While I listen to jazz and acoustical music I had found a couple speakers sounded better with that kind of music, others better with Rock and so on. So I learned it’s not that there are really good speakers or terrible ones, it is moreso what you like for the kind of music you enjoy. I settled on Magnepan for one system and Vandersteen for my higher end system. I made sure to match the speakers to the capability of the amp, running tubes with the Vandy and SS with the Maggies.

Here's a few of the more recent threads on speakers (my reccomendation).

Thanks @gnostalgick for the threads. I read the one on the 4k speaker price. Question for you... do you think my elektronics currently support moving up in to a better speaker ?

I'm no expert but it all seems solid to me.  The Pro-ject is a classic, Jolida is IMO underrated, and Hypex has a good many fans and should power most anything (maybe not planars?)

Also +1 @2psyop's response above.

thanks for your thohghts on my current gear. https://forum.audiogon.com/users/gnostalgick  I agree with @2psyop  that to listen is to know. I prefer "rock" but listen everything M83 to Let it Bleed to Kind of Blue (except for twang). I did audition new speakers a month ago, maggie 1.6s with ReL subs and really liked it. But then had the original question pop in my head.... "does my current stack of gear warrant the speaker uogrades now or should I still be working on the gear first?" Thanks agian for commnets that specifically address and contrast the current gear versus the upside of upgrading the current speakers.

Maybe my question is lame. ;-)
