Does anyone use Yamaha BD-S671 for stereo? Alternatives?

 Does anyone use Yamaha BD-S671 for stereo? Alternatives?
 
I am interested because:
1. It is only $299
2. It has USB “thumb drive” support, I do not have that today and want to try,
Putting my music on thumb drive from my PC and then play it on this unit.
Why:  my Arcam rDAC sounds great via my current DVD player (via CDs that I burn via my PC) via the digital coaxial output
to same input on the rDAC >>>>but sounds “electronic”, not real, especially cymbals and other
Higher frequency instruments and voices, when using the PC to rDAC via USB ports<<<<<
3. It does have the digital coaxial outputs needed for my rDAC.
4. It has more front panel controls than other similar priced units, if I am near the unit and don’t have the remote handy, I can change the track…
5.  It can be my back up DVD and Blu ray player (and supports 3D which I do not have now) BUT: actually features 1 to 4 are much more important.
 
How does it work, is it functionally OK, solid, as a USB thumb drive “player”?
How does it sound playing CDs, if using it’s regular analog RCA outputs? How does it sound Compared to what?
