Empty canvas: recommendations on blending audio and moving watching

I am in the process of finishing my basement, including a room approximately 20' x 25'x that I plan to use for both TV/movie watching and audio listening.

I enjoy an occasional streaming program on HBO or Netflix and in my current TV room I have the TV connected to a set of stand-mount speakers driven by a small amp - more than use the TV speakers, but not a big 5.1 surround sound set up (something I've never been that interested in).

For the new room I am excited to finally move forward with a tube-based system (my prior years have all been SS) with speakers such as Devore O/96 (or Gibbon Super 9).  My question is, if this is the audio configuration, what to do with the TV audio?  Running TV audio through sensitive speakers like Devore doesn't seem like a good idea.  Would a speaker bar for the TV suffice?  Or is there another configuration for the TV sound that would be better.

Recommendations welcome!
I'm not sure what your problem is.  The TV out put is line level, not speaker level.  It will need a preamp and amp. Your speaker sensitivity would be irrelevant.
Just use the TV line out into your preamp. Why should the DeVores complain? You might need a DAC (you can get one for $20 on Amazon if the TV output is optical only.
Digital out from the tv will work fine.
However, to get real movie sound you either need a sound bar, center channel speaker or similar.
Most TV's have crummy sound.  However, some of the nicer TV's have some higher quality sound built in, including ATMOS.  Look at the LG OLED TV's.  Not cheap but amazing picture and the sound will do a decent job.  I have the 65 and the sound is fairly good.
This is what you do. https://systems.audiogon.com/systems/8367
You can have TV instead of projection. You run the sound right into the amp. Simple. I watch most movies off my laptop, but regardless of source its all the same, you keep the video and the audio separate. By far the best sound you can possibly get, video or audio, for the money.

In fact when it comes to video its the best sound you can get, period. 

     For tv/movie setup I would definitely separate the audio from the video as millercarbon stated and use a top of the line video picture format like OLED, which is a bit more expensive but picture quality can't  be beat by any other currently available technology.
     For audio, the sound from just the tv might be acceptable for some but everything will sound significantly better through at least a 5.1 home theater surround system.  The "5" represents 5 channels and speakers ( front l+r channel main speakers, a center channel speaker and rear l+r surround channel speakers) and the ".1" represents a subwoofer. 
     The most efficient and least expensive method to achieve a good quality 5.1 or 7.1 system (7.1 just adds a pair of l+r side speakers) is to buy a high quality blu-ray player, such as a new or used Oppo player among others, that has a built-in 5-7.1 surround channel processor along with analog outputs for all 5-7 audio channels along with a sub output.  You'll just need the speakers, rca cables and amplification. 
     The Atmos surround format adds a pair of ceiling channels with devoted speakers for height perception that some prefer. I've always preferred a high quality 5.1 system with 2 or more subs for a good balance between sq and simplicity. For Atmos, you'll need the video source content software and surround processor hardware to be Atmos compatible. 
    I'd suggest auditioning some good quality 5.1 to Atmos systems with one and multiple subs to determine which you prefer.  I also think you should look into a multiple channel solid state class AB or D amp to drive your multiple surround channels, the sub(s) typically are self amplified.  SS multi-channel surround channel amps will  produce less heat, are more efficient and more reliable  than tube amps, especially for home theater use.
