I have an AVM 2 used in HT and 2 channel. I would run the CD to the tube preamp and then the preamp to the direct inputs (5 or six channels available for direct DVD inputs but works fine for any analog signal) on the AVM 20.
That way you bypass all the circuits in the AVM 20 except the volume control and take the direct input from the tube pre to through the AVM and to the amp.
You simply select direct input on the AVM 20 when you want 2 channel and if the tube pre does not have a remote the AVM 20 volume control works for this. YOu do not need the extra set of cables to your amp.
