Photos of my system

You are well on your way now. Congratulations. Enjoy the music!  :) 

@decooney You get extra special thanks for an enormous amount of help and patience with my constant questions.

@hilde45, you may want to restart the Amazon HD app from time to time which could help with dropouts.
A simple restart (phone, Node etc.) could help narrow down errors in the streaming line.
Amazon HD is at least 44 / 16 files (HD) with 96 / 24 being more common than 192 / 24 files.
My phone (Android) app (Amazon Music) allows me to check the stream rate, file quality and device capability (PC app and Android).

The reduced soundstage depth with the IN 200 is a big difference.

It seems (to me) that the QS System (as described) brings the cohesion that you would prefer even over the 'Hybrid' combo.

The Orchid performance is still of some interest as I am looking for a DAC that delivers at a high level.

A broadband panel would help with higher frequencies (a range) to help with perceived brightness issues.
You have an opportunity play with treatment and placement in such an open space.

 

Thanks @rego Good suggestions. I'm very happy with the Orchid. LTA's return policy is here: https://www.lineartubeaudio.com/inhome-trial
They're easy and friendly to deal with.
Looking forward to playing with the space. It's basement, too, so I can be a bit man-cave-ish about things.

Wow, great looking system! And I would bet it sounds even better than it looks! Also, thanks for sharing the playlist. Happy Listening!
