Discerning a difference between streamers is difficult...only me or common for all?

Why not a Innuos Zenith mk3. It has a cd ripper ,a Nice SS drive  fantastic interface 

3 separate LPS power supplies ,isolation damping everywhere including the Teac cd ripper and SS drive,and excellent iso bearing feet ,and the Excellent  Mundorf Mlytic  capacitors , plus the innuos sense app is very intuitive .

the  Zen with reclocker sounds actually a bit better ,

i use my own Gaia reclocker , the sense app puts folders and playlists together seamlessly and sounds better then Roon which is a big bonus setting up judt hit the app button found and yiu just pick configurations the  most thought out streamer 

I have found to date and this is a bit warmer sounding due to the Mundorf caps .

tip if you want your digital to sound better still Tubulus Audio cables ,they beat cables much more $$ and only true I2S  -Audio cable  the AQ dragon audio only exception ,and the less expensive Tubulus Concentus is much better. And Ethernet cables very good ,always put your best Ethernet cable at your end point- Streamer 

land Router put a good LPS to block incoming noise,Thst cheap wall wart judt ads noise to your audio chain,digital house to house is not grounded !                      Linear Tube Audio-  excellent LPS for $750.

streamers don’t have a sound or different tonality (assuming no differences re up- or oversampling, etc.).  They have different levels of noise, but even there, the differences between relatively cheap but well-engineered streamers and insanely expensive ones can be subtle or nonexistent.  Noise levels can affect how well you’re hearing your DAC, but if it’s a decent streamer, your DAC dominates what you hear.

I have basically the same system for 5 yrs but added several things to make it sound better. I have a Node 2i with a Pd Creative power supply and aftermarket power cord. It sits on Herbie’s dots. The router has a linear power supply. I run a Cat 6 Blue Jeans Cable from the router to the streamer. There is a noise filter on each end of the ethernet cable. DX Engineering filters $50. I am using a Topping D 90 with aftermarket power cord. It also has Herbie’s under it. This was good sounding. Then I added a Furman Elite power conditioner. Also bought Furman power strips and plugged all the noisy phone chargers etc. Into the strips. I tried silver coated interconnects and OCC copper. Ended up with a mix of each for the cabling.

All the extras have added quite a bit to the sound of my system. If one of these changes were added it made a difference, but cumulatively made a huge improvement. Power, detailed pleasant 25 Hz bass, transients I never knew were there. The sound is just smooth and not fatiguing. Bear in mind component isolation,  cords, cables, power conditioning all are on the budget side.  You could easily spend thousands more for more expensive brands.

I will save all the software issues for a later date. QOBUZ and BLUOS has been nothing but problems.

It's always complicated to apply our feelings and experiences to others.  I'd just advise you to stop worrying, as forums, online stores and tests always make you believe that your equipment is absolutely brilliant, but it's very rare to read a complete description of the listening room, the equipment and the way it's used. Not to mention your own listening habits.
I've had the same Innuos streamer for 4 years, with basic Oyaide cables, and it works well. I'm not looking for a rare pearl, a magic cable, I just listen to the music.
If you're brave enough there are of course other brands at all prices, but in the end the question is “what do you miss today when you listen to music?”

I think one of your “issues” is that Bluesound Nodes/Nanos work very well when used as streamers that feed a high quality external DAC. I use a NODE 130 that I purchased from Fidelity Audio in the UK with FA’s PSU unit pre-installed and then added a Gustard X26 Pro DAC and then later a Innuos Phoenix USB reclocker. At this point, I think I would buy a better DAC before looking for a better streamer (though since I’m out of components to upgrade, Immopen to suggestions as to what streamer or DAC would make a noticeable difference in SQ

(the rest of my system consists of a Bryston 4B3, Primaluna Evo 400 pre bi-wired to Tannoy Cheviots with SR Foundation or better cabling and PCs throughout)(I suspect the best thing I could do would be to upgrade my speakers, but my wife hates tower speakers and would not go for anything that is physically bigger)
