Seeing all these responses is wonderful. This is all new to me and I have been given a lot to go from - thank you everyone! I'm sure others will benefit as well.
I will share that I just bought this Conrad Johnson HD3 USB DAC because it is the same brand as my other electronics (see original post that began this thread + I also have Conrad Johnson DV2B Tube CD player). I thought this could get me going with streaming. CJ puts it this way for this DAC "The HD3 is an audiophile grade digital to analog converter for use with a computer based audio source".
This DAC only has a USB input.
Silly Question: Are there Streamers that can connect to a USB only device like this?
Thank you!
