Hello Springlike. Yes, we could be on the same page. I feel that my own DSP5200SE speakers crossed a line where they finally disappeared altogether into a big 3D soundstage once I put them on Gaia II feet, gave them decent Shunyata power, and implemented a couple of network changes, including a singlemode fiber segment. I didn’t add the Diretta endpoint for Roon until early 2024, which brought everything into a sharper focus

I never owned the MS600 or used the Sooloos software, but understand that you would need to replace it as a streamer with something that can incorporate the Diretta protocol to get SQ benefits. A Raspberry Pi 4 or 5 can be made to output SPDIF or AES which your DSP5200SE can use. MQA is on the menu, too. The problem for Meridian owners is that we like to use SpeakerLink or BNC Comms to control all aspects of music playback, whereas I now have only volume control and on/off using the remote unless I temporarily reconnect an M controller to adjust something like balance, for example.

The Diretta protocol was developed in Japan by otherwise smart people who have so far done terrible jobs with documentation and marketing for us English speakers. So the information I have is gleaned from a couple of Linux software partners: GentooPlayer and Audiolinux. You can buy standalone hardware devices from them or install licensed software on the RPi like I did.

Oops! Right now I have to run for a birthday dinner, so I’ll check back again here once I can.
