NSD CSI.    My apologies.  I really need to get more sleep than I am getting.  It is a "NAD" Model Number CS1 (Compact Streamer 1).  Small form factor, with a RJ45 for dedicated network connections.  I stream 100% at this point.  The rest of the system. The other purchases, I wish I could say were all very well-informed.  Far from it. I am new to audio. Brand new. I've been in it for about 5-6 years. Only 3 years with decent equipment that works. I have always loved tube gear, and would like to have a second system built around a Decware amp. As far as speakers for a Decware amp, I need to make that decision in the 6 months or so.  My budget for speakers is about $4K. It's been trial and error ever step of the way.  Thank you for your questions. They got me thinking about things.  VR, Rob.  Please give me your thoughts one speakers for Decware tube amps.

I'll say here what I told Rob in an email: My experience with speakers and Decware amps is not extensive, but of all that I have tried the HR-1 has a magic with all the amps I've tried them with that no other has, though the ERR come close they don't have the lower frequency authority that adds to the 3 dimensional tapesty they conjure up. I hate to suggest another waiting list endurance program, but that would be my recommendation, and I suspect the latest model is even better than my two seasoned pairs are.
