I suggest you sell your Levinson pre and purchase a Proceed AVP. Its a HT pre/processor that contains many of the best Levinson components (such as their best multibit DACS in the right and left channels). I'm very happy with it.
How do I listen to stereo audio?
How can I have the best of both worlds. I want to convert my audio system to home theater via the Bryston 9b. I want to be able to keep my Levinson preamp and use that for listening to stereo, but then use a surround processor for theater. How can I do this, do some good processors have some sort of passive pass through. Thanks. Matt
