Streaming? I know nothing about it, questions as to sound.

Thanks, your answers go directly to the point.  Take care, Jim

Another source for high resolution streaming audio is Amazon Music HD. I’ve been testing it and am quite impressed. If you’re already an Amazon Prime member the additional cost is very reasonable. But what may be most important in deciding on a streaming service is which of the catalogs most nearly matches your musical preferences. Trial memberships are the way to explore that. The Ultra HD tracks on Amazon Music HD often sound better than the same CD in my system.

I feel a good server slash streamer is essential to streaming quality.

Bluesound Node can be a starter device.
