Photos of my system

@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! 

@barkeyzee1 It sounds delightful, luscious! And I do have some (a lot) of envy for many of the really beautiful systems and setups. Platforms for the amps, a gorgeous rack, lovely room, etc. At some point, I'll get there, but to start out I needed to spend only on the equipment. And because I only have one sub that I'm running high-level inputs on, I need to scrunch the tube amps close together.

Luckily, there are few benefits to my setup space. There's a bookshelf running all along the back wall, the floor is concrete with a carpet for some absorption, there are no first reflection points on the sides, and (most important), this is just my space. No one else ever needs to use it. 

Can't beat SALK audio.  Wonder why you didn't end up with Tower's?  What kind of subwoofer is that?  Would you benefit from adding another sub?
