What should my next upgrade be? Your best experience

I have the itch to upgrade my system now that I've been in it for a moment. I mostly stream (Deezer) or listen to CD/SACD content. I occasionally play vinyl but rarely, I'm sure I will continue to grow into it but am not looking to improve the TT now. I listen to mostly Classic Rock, Jazz, Blues, and Indie music. I'm listening to Talking Heads (live acoustic) as I write this. The Marantz PM-11s3 has zero issues pushing the Monitor Audio Silver 8s, it actually is a little over kill for them I think, as it has complete control of them, never losing its composure.  So there is zero chance the PM-11s3 is up for replacement at this point.
The room is 14'x40' with 12' ceilings. The system has no issue filling every inch and at high volumes so no issue there.

Current system is -

Marantz PM-11s3
Marantz UD7007
Marantz TT-42 
Sonos Connect
Monitor Audio Silver 8's
Analysis Plus Purple Oval 12 bi-wire
Tributaries 8AB XLR (UD7007 to PM-11s3)
Tributaries 2A RCA (Sonos to PM-11s3)
CyberPower Conditioner

The obvious direction, it seems to me, is speakers? But am I missing something? Would upgrading to a real audio quality conditioner with an upgraded power cable give me something more and set me in the right direction for future upgrades? 
Or am I not where I need to be with cables? Can I make a sonic improvement by upgrading speaker cables and/or interconnects while again getting myself in a good position for future upgrades?
I have to admit that this is the best system I've had and I do love every minute of listening to it.... Its fast, accurate, and punchy yet it has great sound stage and its not clinical. It has that Marantz sound/charm (warm but not clouded).
I know posts like this are common and beaten to death but my system is unique as it is mine and probably not exactly like anybody else's...
Never-the-less, I know I'm nowhere near where most of you are! And I know for a fact I have much less knowledge than most of you. I'd like to keep bettering my system, moving towards the personal listening nirvana if you will. So what direction would you head in if you were in my shoes?

If there is a sonic difference it may come from a better DAC in your Marantz. However, other causes may be differences in signal level (louder sounds better) or because you may not be playing the same masterings (from what I understand you compared cd and streaming - they may be from different mastering). So it may not be quite so obvious that the Sonos DAC is the culprit.
From what I understand you can wire the Sonos into your ethernet network. That way you would be sending a digital signal to the Marantz and not use the Sonos' DAC.

Coming back to your original question, I think the best upgrade would be to look into the room. Buy yourself a calibrated measurement microphone, download REW into your computer, and have a look at the in room frequency response. You may be horrified by the low frequency response. You can create an equalization curve in REW and apply that to your computer with something like Equalizer APO (a no cost option), and if you like the improvement, download it into a mini DSP so you can also use it with other sources. Obviously bass traps and the like are another option, but more costly and ugly.

@264win,

Upgrading to better RCA IC’s is not an answer, IMHO. The culprit is subpar Sonos internal DAC. The only way to improve sound from SONOS is to use its SPDIF output to an external DAC.

Your Marantz 7007 doesn’t have digital input so don’t think you can use 7007’s internal DAC for streaming from Deezer. 

Either you try another Streamer with built in DAC or buy an external DAC to use with SONOS. You can also look into Oppo UDP-205 or 105D. 

Keep in mind, with Sonos you are restricted to CD quality resolution at best through its digital output. 

There are lots of DAC options so take your time to choose wisely. 

Or try Bluesound Node 2 and see that make audible improvements in your system. 

Good luck!

I have a Sonos Connect in second system and the sound quality is not very good. For main system I use Wyred 4 Sound modified Sonos Connect and Exogal Comet Plus DAC and it sounds great. Wyred will modify your Sonos.

An outboard DAC can help the stock Sonos but is still limited...
