I have a similar set up to most of you here. Using a Meridian 568.2 with L & R output going thru a Aesthetix Calypso. For pass thru the Calypso is set to unit gain. Which I think sounds better. As I have only a dvd transport, when I listen to 2 channel, I take the calypso out of unity gain. I generally set the meridian to maximum gain and adjust the volume with the calypso, which to me sounds much better.
The only tube preamp I have read that has a thru bypass is the Cary SLP 05 or Cary SLP 2002.
