A thin and elegant system?

The weight isn't an issue - just a way of summing up the mass of it all.

I appreciate the answers, but most of these are simply boxes with drivers on the front face - and yes I know the reasons for that - but I think I am after alternative designs.  The KEF Blade is a good, albiet expensive, example.   Perhaps speakers that have a sculptural sensibilty over the traditional box tower?

My base system summarized:  Benchmark DAC2 + Benchmark AHB2 + microRendu + KEF LS50 speakers = $6200.  Buying a used DAC2 and KEF speakers would get me to $5K for the base system. The listed items are super light and small. 

My suggestion is an Benchmark DAC2 (with 2 analog inputs and volume control), the Benchmark AHB2 amp, a Sonare microRendu, ROON or JRiver music server software, TIDAL monthly subscription, a computer in a far away room, a mobile communication device (iPad, Surface, iPhone, Android). I think you will have many speakers to choose from with the AHB2 amp. I have my TV, XBox, and microRendu connected to the digital inputs on the DAC2. I have an analog tuner that I have connected to the analog input on the DAC2. I have a remote for the DAC2. I use the mobile communication device with a ROON app to talk to my noisy computer which is at the other end of the house. I have a direct Ethernet wire from my network router to the mircoRendu (which connects to the USB input of the DAC2). You can also use D-link type of wired connections (or even wifi via some device) for the computer and microRendu but I prefer the reliability of the wired connection to my DAC. Notice that I have a noisy computer, it does not matter with the microRendu.

BTW - read the SoundStage comparison of the Devialet to the Benchmark AHB2. The AHB2 is quieter and a lot cheaper.

I plan to upgrade to the KEF Blade2 and buy a second AHB2 amp and switch them to monoblock mode.

So if it will be not thin, but just small? Like Spatial, Omega XRS, Ohm Walsh Tall and etc.

If you want something stylish and different, without the box, I suggest you check out the Spatial Audio speakers. They can't be placed against the wall, but they sound as good as anything out there, and look much "lighter" and hip than your typical tower.
