Going into more detail about what I am trying to configure.
I don’t currently have any equipment yet. I’m trying to decide if a Roon/Rose RS150 combination is the way I want to go. The audio equipment I’ve settled on is a McIntosh MX180 and associated amps, etc.
I want to use Roon because of its Music media management capabilities, not its digital signal processing capabilities. Roon’s media management is fantastic. I don’t need its or want signal processing capabilities. Will I be able to do this with Roon?
It doesn’t make sense that Roon would convert everything to PCM but if it does I’d have to look elsewhere for media management software.
I know I can just plug things in and try it out, but that’s a lot of time and effort. Also, it may turn out that the RS150 is the wrong choice if I am going to be using Roon.
Now for some questions that will help me figure out what I need to know.
I’m still trying to understand what Roon Ready an Roon Tested mean. I am planing on using Roon with a Rose RS150B streamer which is both Roon Ready and Roon Tested.
The Roon Partners web page, 75+ Roon Ready Partners - Network Players, Devices & Core Servers, has some marketing (sorry) gobbledygook about Roon Ready/Roon Tested equipment. It says “supports the highest level of audio performance”. I don’t have any idea what that means.
Does “Highest level of audio performance…” mean that Roon will send a stream that has been dumbed down to what that device can handle? I’ve tried Roon on a Mac mini connect to a Sony TV via HDMI and this is what it appears to to do.
So, does it mean that Roon will send the raw audio stream to the RS150 because that device can handle most any audio from CD/PCM to MQA or HighRes? This is what I want.
Digging further into the Roon site, https://help.roonlabs.com/portal/en/kb/roon-labs-llc/audio/roon-advanced-audio-transport, it looks like “Roon Ready” means the device supports RAAT, a Roon protocol for communications with a device. Is that correct?
In practice I think what this means is that the developer of the device has obtained some kind of development kit and maybe a license from Roon. It does not mean that the developer has property implemented the RAAT protocol.
Further” Roon Tested” means that Roon has actually tested that the device properly supports the RAAT protocol. Is that correct?
I presume this means that there is someone at Roon that knows if the raw audio stream is sent to the RS150. Could that person chime in?
There is no reason for Roon to do any signal processing to a music stream sent to the RS150 because the RS150 can already handle all the formats I’m interested in directly, for example FLAC, DSD, PCM, MQA and many more, natively. All the reviews I’ve seen of RS150 say that the RS150’s processing of these formats is stellar. Also an audio engineer I’m working with to configure my system agrees that the RS150’s output is great.
Going back to the marketing stuff on Partner’s page… “Every Roon Ready player is certified by Roon to guarantee the same stellar experience, regardless of its manufacturer, its price, or its features.”
Does this mean the by using RAAT Roon will be able to tell the audio formats that the RS150 handles and just send the raw file data to it, i.e. skip the audio processing step?
Can I configure to skip all signal processing?
How would Roon/RS150 system be put together. Here is an example of one:
Router-> ethernet cable->Mac mini (Roon installed) →
Mac Mini → USB-C output → USB C B cable-> RS150 USB B input
→ RS150 Coax Digital Out → MX180 Coax Digital in
Will it work?
Some recordings now are Surround or Atmos encoded. I’m not saying they do Surround well but they do exist and by using a full digital path from Roon to MX180 I wlll be able to play them in Surround/Atmos.
If I substitute Nucleus for the Mac mini would this config be correct?
Router-> ethernet cable->Nucleus->
→ USB-A output → USB A B cable-> RS150 USB B input
→ RS150 Coax Digital Out → MX180 Coax Digital in
I would prefer to use Nucleus.
I sorry that this is a bit on the long side but the Roon site doesn’t provide much in the way of detail as to how it processes audio. Thanks to everyone who takes the time to read this.
