Seeking help finding the weak link(s) in my system and offering suggestions please.


Hi! I recently paid a visit to a local audio salon and listened to a system that was so good I was "moved". However, I could never afford the price of entry to realize this kind of sound reproduction. I have spent the last couple of years assembling a system I could afford, focusing on components I felt were the best bang for the buck. I'm not trying to make a silk purse out of a sow's ear, however with your help I am hoping to find where I may have a weak link or two. My budget makes this a challenge as I have only about 1K to invest. Thank you to all those in advance for your suggestions, my system is listed below. One more item, about 90% of my listening is Qobuz streaming.

System:
Dedicated/Isolated 20Amp AC source with PS Audio outlet.
Furman AC power conditioning.
Nordost Magus Power cords for source equipment and Kimber PK10 for Amp.
Ethernet cables all CAT7.
Kimber Silver Streak both balanced and SE throughout.
Speaker cables are Blue-Jeans 10AWG White - two 15' pair.
USB cable from PC to streamer is Audio Adviser Pangea SE 2 meter.
Canare/Have digital 1.5M coax from transport to Streamer.
Krell Vanguard Integrated Amp.
Cambridge Audio AZURE 851N Streamer/DAC.
Sonus Faber Electa monitors.
Sunfire HRS series subwoofer.
Sony SCD2000ES Transport/SACD player.
Luxman T117 Tuner (Best sounding component)?

Again, I appreciate your kind assistance, I am really looking forward to responses!

Well, I’ll be the contrarian opinion in the discussion; cables and tweaks won’t get you from where you are to where you want to be. In 90% of the cases, what you are hearing is 90% the speakers/room combination. Assuming this to be true, and you really liked what the B&W speakers had to offer sonically, Maybe you should inquire into the smaller D series 805 and see if that yields some of the improvement you are looking for. Also, this is a small enough unit to perhaps try in your own space prior to financially committing to them as speaker choices can be highly personal based upon your sound preferences. Tweaks and cables are what you play around with to fine tune a system you are already mostly settled in with, not to effect gross systemic improvements. There’s a reason why there are so many cables for sale here from disappointed buyers who thought they could extract an order of magnitude improvement from their systems with a cable purchase. 
"Two HFT Speaker Kits and one set of HFT " Lmao! I had to look up what this was. What a joke, That could not possibly help in any way but drain your wallet..A power cable makes more since…..Folks believe in anything….Santa is coming soon...
Hey GRM... lots of great suggestions here. I'm curious if you have a clear direction to pursue. Curious to know what changes you make... the results... and if the results are enough that you are content.My System sounded incredible... but I could always sense something was not quite right. It took better power cords $1,000 each replacing $400 cords, and interconnects. After that it was speaker position, room tuning, and tweaks. I figure that if a person does everything possible to make the system sound good but you are not happy... THEN start swapping out components.
GRM, just add a second subwoofer and bring the crossover point up to about 100 Hz. Make sure you have a high pass filter on you main speakers. I am not sure if the sunfires provide this but it is critical for the best performance. This will improve your bass and give you another 6 dB 
or so of head room. The high pass filter will also lower the distortion levels in your main speakers.
