Would I benefit from a dedicated streamer?

I use Roon on a dedicated Mac then going to a ps audio DS sr dac using Ethernet. I have used many software apps like audirvana and pure music on servers and then went to an Auralic Aries music server, all using usb to an external dac. I will never go back to usb until it gets better.
When Running over Ethernet or even i2s, you don’t have to worry about usb specs which is often a feature that differentiates manufacturers. I also like the sound better going directly into a BHK amp from the DS dac compared to using a quality preamp.

I'm sticking with a dedicated barebones Acer laptop AMD CPU/20 Gb Ram , running Windows 10 and enhanced with AudiophileOptimizer,Fidelizer ,ProcessLasso and ParkControl.
I would consider a dedicated streamer if significant SQ gains were achievable , but no return policy on any products here in Thailand.

I’ve found the Bricasti M5 a superb streamer, it just sounds very right. I use it with an Network Acoustics ENO filter and Ethernet cable on the input and find the AES output sounds the best.

@arafiq the wolf server does not need anything but a keyboard, a mouse and a nice usb audio cable. If someone is looking to stream dsd they need the usb anyway so i dont count that in the cost. 
The u1 is $6100 
the used aurender was 16g 

As far as sound quality.... the stage is incredible. You can mentally zoom in on the individual performers just like at a real concert.  The detail is staggering, and ill say i have improved dynamics, air, and tonal accuracy. 
I grew up in a studio and have been critical about sound my whole life. The op asked for opinions... i just went through the same thing as the op and this is where i landed. Take it or leave it. 

@andrewkelley - thanks for the follow-up. So,the Wolf Luna R is the steamer, right? It replaced the Mac Mini/Metrum Amber? Did you get the Luna R or the Luna R Pure Digital version?  May I ask what DAC you’re using?
