I have a similar set up as oldschool1948 and ejr1953
When I went down the streaming rabbit hole, I started with Roon and thus no experience with alternatives to Roon
I do not have a Roon Nucleus as I have no need to store files
I started with a Roon core running on a Lenovo i4 laptop with 8Gb of RAM, no SSD and wifi connected to my network - it was functional but not entirely stable
I upgraded the laptop to an i7 processor, 16Gb RAM, with some SSD and wired direct to the network switch
I do not know that the SQ improved but the stability was better requiring fewer reboots and dropped songs
For the record I've never had a song drop on Tidal, with Qobuz I drop approx 10% of the songs
In both cases I found the Roon SQ to be exceptional
I hear the best versions of the same old songs I've listened to for the last 40 years, streaming through Roon to my PS Audio DSD
I cannot recall the last time a played a physical CD
If I could change anything I'd like to remove Microsoft from the equation, not sure that would improve the SQ but all the bloat, OneDrive, AV, patching updates, etc - the timing of such is typically not convenient and I'd like to spend less time babysitting Bill Gates and more time listening to music
I'm happy with Roon and only wished I'd bought a lifetime subscription the first or second year
Happy listening guys and enjoy the journey
