What are you using as a streamer? Constructive feedback please.

@pdreher - yes, I did.  Both the Bricasti and Auralic showed improvements.  Probably the best bang for the buck is the Bricasti network option at a $1000 add-on (but you do need software to stream to - MCAST is free; I use Roon on a SGC i5 server).  As the Bricasti has a large onboard cache, it seems to be invariant to the server with respect to sound quality.  (That said, a filter such as the Network Acoustics ENO does seem to improve the sound slightly by decreasing electric noise to the unit.)  The Auralic is also better than the Bluesound, including the Bluesound with the power supply upgrade.  Just a little more detail and soundstage.  The Auralic software also sounds better than Roon using the Auralic as an endpoint.  I also like the screen the Auralic has as well as options to upsample and use different filters.  All small improvements.  

All that said, the Bluesound with the upgrade is really quite good and I believe a great value, esp given the included software ecosystem.  You might be able to do better with a Pi based DIY solution, but that may not appeal to everyone.  If you told me I could only stream the Bluesound and never use anything better, well I wouldn't be too upset.  I think the Bluesound is a great entry point for those who want to stream, and for many could be an endpoint.

I amusing a computer I built with Noktua biggest radiator and SS drives using Linux 

operatung system   On the Ethernet input the excellent uptone audio Ether regen which cleans the incoming Ethernet it’s nice hub , Wire World starlight Ethernet cable ,  USB cable  Audiogon - Grannyring makes Excellent quality Great value cables Acoustic BBQ ,going to a Denafrips Iris DDC Reclocker  , Clock sync  BNC cables ,then I2S cables all Wire World to New Terminator-2  Dac  which I use Roon  
and QObuz  toWestern DigitalSS drives. Until I decide to spend $5-6k  on a dedicated streamer server  this sounds very good.

My set up is: Roon Nucleus+, a Synology NAS DS918+ and a Lumin T2.  The Lumin T2 offers a great soundstage and I just upgraded from a Lumin D2.  I use the Lumin T2 in my main listening area and I have Sonos set up in 7 different zones where I use the Roon, which pulls my ripped CD's from the NAS or stream music from either Tidal or Quboz .  With the Roon you can play different music in every zone at the same time which is great when household members want to hear their own music.  This comes in handy when I am playing music outside, for example, yet others want to hear something else in the house.  One of the best things about Roon is that you can use your smartphone or tablet to control everything and the app is user friendly.

I have an AURALiC Aries (old model) that I use in my second system, and an AURALiC Aries G1 (new model) that I'm using in my main system. These are awesome streamers. You can use the AURALiC app to stream, or you can use ROON. Also, they work very well with Apple Air Play. Either way, they work really well. The one caveat I have is that the new AURALiC products don't come with remote controls for some reason. They say you can use any "universal" remote. I tried that and didn't like it. So, I ordered an AURALiC remote from Upscale Audio. It works great! Why didn't they just include this with the product? Not sure. Anyway, bottom line is that I very highly recommend the AURALiC products.

I use computers with Qobuz and Media Center software. I run the feed from the computer to either a Marantz AV amp in my home theater system or CEC DA5 dac in my stereo system.

Both computers are custom. The one used in the stereo system has an analog power supply to help reduce noise.

I tried Tidal, I decided I like Qobuz better.

I make my own cabling (Kleinbeck Engineering) because I don't like the performance of other brands. I prefer musical,  low noise, electrically accurate designs of cabling.
