You can have "HT Bypass" on any preamp with Aux in's...I used to own an Aurieges. Simply plug your mains cables into the Aux input, set the vol dial to something specific, like 12 o'clock, then volume adjust using the HT remote to control overall volume. Anytime you want to watch movies, switch your Shindo over to Aux and set the dial to your set position.
It's not true bypass per se, but it worked just fine for me. More info on this method can be found online.
