@gkelly I'm on a fixed income as well in that I have to strategically make hi-fi purchases relating to substantial upgrades. I have a family to raise and the kids and wife seem to vacuum up my $ and time. But that's life right?
I have a modest mid-Fi system that consists of a Cambridge CD player, the CXN-V2 streamer/DAC, Marantz AVR (used primarily as a preamp for 2-channel listening), a vintage Adcom GFA-2 amp, Rega Planar 3 and mid-tier Polk Audio monitor speakers. AQ Evergreen connects. I plan to make some tweaks by upgrading my speakers and maybe swapping out the Marantz and Adcom combo for a better integrated amp w/ a phono stage. I can't justify buying nor do I want to have tons of separates.
I stream via Spotify and Radio Paradise for general streaming and previewing music. I have a mix of vinyl, digital files and CDs. I've been ripping older CDs I don't want to keep or listen to that much as FLAC files and purging. I only really buy specific artists that I like and want to enjoy higher quality/better listening experience. I get not wanting to have a ton of physical media. It takes up space and with streaming you can enjoy an infinite amount of great albums with little investment. My recommendation is purchasing only the music that means the most to you or gives you the greatest listening satisfaction or if you're a completist for certain artists. I'm one album away from having all of the New Pornographers on vinyl, ditto w/ Calexico and some other favorites of mine. I'm limited on space and my wife already things I'm too high maintenance w/ my space requirements for my music and book collections.
