I’ve been streaming for over 20 years now with many different software applications: Apple iTunes in the early 2000’s, amarra, pure music, audirvana, lightning ds, lumin, (using upnp and minimserver), roon, and Qobuz connect. 20 years ago I got rid of my $3500 Classe cd player because ripped music sounded better than from a cd. I still have my 20+ year old Sony SACD player which still sounds good but I’ve used it 5 times in the last 15 years.
Software does effect the sound quality as does the hardware and OS you are running it on. All the software up until auralic’s lightning DS ran on a Mac, I ran lightning ds and the lumin software on the Auralic Aries streamer/server.
I got rid of all my usb crap (Auralic server, dac) and went with a much better dac with Ethernet which sounds better than usb and went with Roon. Years ago, I tried Roon on both a Mac and a $50k enterprise server I had and the sound quality was the same, so I kept running roon on a Mac with the latest being a m1 Mac mini with 16g ram and 512G ssd. In the last year, I did eval audirvana against roon and I thought the sound quality was better under audirvana, but I hated the interface so I kept using roon.
A month ago, I decided to eval roon on Linux again so I bought an older Mac Pro 6 core Intel with 32G ram and put on Mint Linux. Sound quality improved and it was subtle. I’m even sharing all the ssd where the music is on from the Mac server (like a NAS setup), I have no local disk on the Linux server except a 120G ssd for the roon backups. I had a couple of my audiophile friends listen to the 2 servers and they also indicated that the Linux server sounded better.
In the last 2 weeks, my airlens streamer got a new firmware upgrade for Qobuz connect and Connect sounds better than roon, again not subtle since my friends all indicated this sounded better. Right now, I can’t live with the Connect app, plus I have thousands of cds ripped to my server that connect can’t access. If Connect updates their gui, I might migrate to that in the future, but since I have ripped dsd files and Roon still sounds good, I’m using roon.
I sold my $15k TT setup/phono preamp and hundreds of vinyl albums because my digital setup sounded better.
