I recently purchased a Schiit Modi 3 DAC - which I love. My source is streamed music (Pandora and Spotify Premium (edit)) from an iPhone 6. I use a 1987 Rotel RE 820 AX integrated amp connected to EV s-40 speakers. Do you think getting a dedicated streamer would offer any noticeable improvement in sound? In particular, I'm interested in using a Raspberry Pi with an Audio HAT. Would this provide any improvement? I'm only 2 days into doing research on this so any info and education would be greatly appreciated.
