New to the forum, glad to have landed here. I looked at a few other places, but I saw they were pretty intense. Anyways... Within the past few days, my Logitech Z5500 computer speaker system started failing. It was a great run, I bought it back in 2008 and the speakers and sub still sound great, but the controller is humming and the input jack is worn out. I stream Spotify into two computers and I use a cheap Rockville DJ mixer to switch from computer to computer (using the fader). And yes, a Raspberry PI streamer with onboard DAC is in my near future. I recently restored/fired up my mid 80's Onkyo system. All original equipment purchased at age 19 in 1986. It's a standalone system and I use it to listen to vinyl and CD's. I also have two other Onkyo AV amps sitting around collecting dust. Listening habits are daily, 8-12 hours. Budget is low-end. What do you guys think, run the computers via the Rockville mixer, into the 80's Onkyo gear? Or, run it thru the Onkyo AV amp? Do I need a preamp if running from the Rockville to the Onkyo AV amp? My concerns with the running everything thru the Onky 80's stuff is that I love the way it sounds, and I would rather "save" its remaining lifespan for listening to vinyl on the PLX-1000 I added to the system. Other suggestions appreciated.
