thanks for all the ideas! i have been looking at the links and googling, and most look feasable. now it is just time to pick a price point and dive in. i will probably start with a low price point item for background listening, then, depending on how much we really use it in the second room, upgrade to somthing more expensive in the future
btw- imhififan, my dac/pre is a naim v1, which has a headphone out, so i can use that without running the tube amp. i can set the headphone out as either fixed volume or variable volume. nice feature.
