Impedance Matching in the Modern Audio System


Hey everyone, I'm still learning a lot about audio and audio equipment. I know that I am supposed to impedance match my components, but my question is this:

If I will have 1 source (In my case a Bluesound Node 2i streaming DAC) that will have an analog out to an integrated amp, do I need to worry about matching the impedance of the analog out on the DAC to the input on the integrated amp? I can't seem to find the impedance for the analog output on the Bluesound Node 2i, but if I were to find it, how would I know if the input is properly matched on the integrated amp?Ā

In general this isn't something we worry about with solid state gear.

"Do I need to worry about matching the analog out on the Bluesound node 2i to the analog input on the tube amp?"

No.
Hi OP:
The issue is generally that Tube OUTPUT stages can't drive a low impedance input.
Your streamer is solid state, therefore it has a solid state OUTPUT stage that feeds the integrated. That the pre/integrated is tube doesn't matter for the sake of the advice I posted.

Best,

Why do people keep referring to SS gear? My source is digital to analog, but the preamp and amp are both tube?
