Hey drussell, i said i made a mistake.  Did u not read what i wrote.  Facts about freya remain the same.  It is not a great preamp for ht use, despite ht references it made in their manual.

The words "home theatre" are not in the owner's manual for the Schiit Freya.
Schiit clearly states that preamp can be used for home theatre use, see the ‘choosing preamp and amp’ section of website.

its misleading if its not a good idea to use for home theater.  For me, it appears dangerous, so i plan to replace it.
I agree that the statement below from Schiit is not what I would think of as HT bypass. It does say the volume has to be all the way up, which would mean the volume is all the way up for all inputs. I think of HT bypass as an input that is not affected by the volume control. That is why reading and understanding instructions is important.

"Home Theater Integration, $0. Okay, all you "home theater bypass" guys. All of our preamps offer true home theater bypass. Just plug in your processor's front channels to any input, select Passive mode, and turn the volume all the way up. Presto! 1:1 home theater bypass, with only a relay in the signal path."
The Musical Fidelity A5 int amp I used to own had HT Bypass and it completely bypasses the preamp section so that not even preouts have any signal on them.  

This was useful in my set up to integrate a single sub for both HT and Music
