Audio Research versus McIntosh tube amps: anyone experience or compare both?
I at one point I had both a Ref 75SE and Pass xa25 in my system. I concur with @chcook's statement " I actually find the XA to have more midrange warmth than the Ref 75. I really like them both a lot - Ref 75 edges out the Pass on soundstage, and ... 
Aurender Now Roon Ready
In my system to my ears the Aurender N200 USB interface sounds better than the Coax interface. When I tried Roon on the N200 output was limited to the Coax interface.

Summary Ethernet cables only transmit two values 0 or 1. The bits transmitted on the cable are not the actual data but a representation of the data. Copper Ethernet cables can transmit electromagnetic noise, absorb electromagnetic noise from th...

Ethernet Switch Ethernet switches connect multiple devices together by physically cabling devices to the same switch or devices connected to another switch. Every Ethernet compatible device has a hard coded physical address called a MAC address...

Ethernet clock There is no specific clock signal passed on an Ethernet cable. The Ethernet specification requires that the transmitted data be self-clocking. This is accomplished through several mechanisms. First is that each Ethernet frame begin...

Ethernet cable, noise and differential signaling Standards govern Ethernet cable construction. The 8P8C specification governs the physical connector on each end of the cable. The RJ45 specification specifies the amount of wires in the cable, the ...

Ethernet data transmission: Ethernet cables transmit binary data. The only two values that can be transmitted are 0 and 1. The transmitter converts a bit value into a voltage value for transmission on the wire (modulation). The receiver converts ...

Media Render: We will now examine the render's processing in a little more detail. The renderer contains a CPU, system memory (RAM) and a system bus. It will also contain a CPU clock which is used to synchronize operations (executing CPU instruct...

Streaming Architecture: Network audio is based upon error free bulk data transfer. It incorporates the same/similar technology that are used for rendering the web page you are currently reading. Qobuz, Tidal, Roon and UPnP/DLNA have similar archi... 
Is positive reinforcement why things are sounding better?
@tonywinga your experience matches mine. I too did not know that Wilson speakers existed until I heard the Watt/Puppy 7's at a dealers. Once I heard them I wanted a pair. I kept my W/P 7's for 20 years and eventually upgraded them to Sasha DAW. In...

Network audio relies on error free bulk data transfer. When the musical data is transferred from the source to the destination the data is broken up into thousands of small data packet/frames. Each chunk of data has an associated checksum. If timi... 
Roon vs OS and Native Players - Impact on SQ?
@mgrif104 I believe the hardware interface between the DAC and source has a bigger impact on the sound than the software being used. (I am not saying that software does not have an impact on the sound) When the hardware interface is usb, AES or S... 
ARC amplifier with Conrad Johnson Preamp
I would second the Premier 17 recommended by @cellorover. But the newer the CJ preamp the less of the sweet tubey sound you will get. CJ preamps have relatively high gain (25 - 26DB with 14 to 20 volt output). You should double check to make sure ... 
ARC amplifier with Conrad Johnson Preamp
I have owned both the ARC ref75se and CJ Premier 14. The two brands work well together it gives you a ying and yang combination. Subsequent CJ pre-amps have better defined bass than the 14.
