Remarkably better sound possible with just 1 system component change?

I could have posted this discussion to a few other categories but chose this one because discussions related to 2 of the 4 components in question belong here.

So it's been ~2.5 yrs since I purchased my current system. I did a lot of research at the time here on audiogon, but no auditioning, and put together a system that sounds very, very good to me.

While I have no complaints, the itch to upgrade has surfaced recently.

I am curious as to whether you guys think it will be possible for me to replace just 1 of my primary 4 components and obtain significantly better sound as a result. The more discernible and obvious the sound improvement, the better obviously. I am not looking for a marginal upgrade - I want dramatically better sound. And I am not looking to replace more than 1 component at this time. I am hoping to get a few ideas/candidates and then may decide to audition some of the recommendations before making a decision. Hopefully some of the upgrade paths are such no-brainers that I may even be able to take a leap of faith without auditioning. Note also that acoustic room treatments are not viable in my current listening location.
 
My current 4 part system:

1. Lumin D2 - 100% of my listening is streaming via Tidal
2. Mcintosh C2600 preamp
3. Mcintosh MC452 amp
4. Focal Kanta 2 speakers

Cables are Cardas Golden presence RCAs from the Lumin to C2600, Cardas Clear Cygnus XLRs from the C2600 to the MC452, and Kimber 8TC speaker cables to the Kantas.

Soundstaging, dynamics, imaging and overall clarity are all great. I have to say I love the Be tweeters. And the bass is punchy, tight, fast and certainly sufficient for my needs. Vocals and overall sound are warm, liquid smooth and analog-like, just the way I like it. (Forgive me if I've botched some of the characterizations - I'm no expert at this). The only thing I can think of that could use some improvement is the sound quality at lower volume levels, although that is not terribly important to me since most of my listening is in the 90+ Db range. Would be nice, though.

So while I do love the overall sound, surely dramatically better sound can be obtained via a 1 component swap? Budget is ~10k. Or will I need to spend more, or upgrade more than 1 component to achieve the desired result?

Thanks in advance for your time and thoughts.

You’ve received a lot of good advice already.

To lower the sound floor and get more detail at low sound volume require power. Your Macs are more than adequate at delivering that. It’s your speakers that are the limiting factor.

Hybrid electrostatics would be able to give you what you are looking for, I’ve been partial to Martin Logan’s.

Here are a pair of ML Expression 13A’s that would fit the bill at $9000:

Be forewarned that they do require at least 3’ of space around them.

My system has all digital input sources and is very similar to yours, though I do have a "PS Audio stack".  Most often I stream Qobuz using my Roon Nucleus Plus server into my PS Audio DirectStream DAC, then into a McIntosh C2500, McIntosh MC452 and Focal Sopra No2's.  I upgraded my PS Audio P10 power regenerator to the new P15 model and that one change improved the soundstage, the detail and improved the definition of the bass.  I also have a pair of JL Audio F113V2 sub woofers, making the improvement in the bass immediately noticeable.

I once purchased 5 new power cables, because I had money burning a hole in my pocket, but didn't believe they would change the sound I had. I put them in place, and went to work. When I got home, I had forgotten about changing the power cables. My wife came from the kitchen, asking what was different as soon as I turned music on. It was THAT noticable. Shocked me to death, cause I was not a believer at all about power cords. I still am shocked today about it. But as good as my system was, a clarity like veil lifting occurred. All of my friends that regularly listened to my system noticed immediately, WITHOUT knowing I had  changed anything. THIS is proof power cables can sound different. At least the Black Sands Violet power cable anyway. I can't speak to any other brands. But this simple one change made a noticeable difference and improvement. Believe it or not, lol. Cause I barely did!

Not to be needlessly redundant, I can’t recommend SRA VR platforms enough. Their improvements when placed under my components is major- night and day.
