I Mac or Streamer for source? or is there a difference?

thanks for a nice compliment 

My impressions of the sound quality from a Pro-ject Stream Box Ultra S2 vs a PC laptop or an iPhone running off of its battery only through three different DACs: Audioquest Dragonfly Red, Rega DAC, Denafrips Ares II:

The streamer made all three of these DACs sound better. Key improvements were a broader soundstage, more precise placement of instruments/voices, better bass definition, and a better sense of musical flow. Not sure if the difference will be the same from an iMac vs my PC laptop. Also, adding a jitter reducer such as an Audioquest Jitterbug can be worthwhile as well for more of the same benefits as a streamer provides.

Hello RockanRoller, I do not have a solution for your question, but a question myself. May I ask for your expertise and guidance? ow can I connect my music collection on a FLAC USB to my pre-amp listed here? My sound system is an early 80s ‘stack’ system.

None of the components are digital: Bryston 2B solid state amp, Conrad-Johnson PV-11 pre-amp, MIT 330 interconnects, MusicWave phase-equalized speaker cables, California Audio Labs CD Alpha and Delta drive, Dual 1129 turntable. B&W 803 speakers.

I would appreciate your suggestions and guidance on the matter.Thank you.

A Mac Mini M1 would serve your streaming purpose very well.
