How do I hook up 2 preamps to one amp

I have a NAD preamp that I use for music. I have a Lexicon preamp that I use for Video. The problem is I have 1 five chanel amp that I need to use for both preamps. When I try to use rca splitters/y adapters, my speakers play at a low volume. If I disconnect one preamp, the speakers play louder. What should I do to allow both preamps access to my 5 channel amp and not have humming or low volume.

I agree with Herman after all. Why use the NAD at all? If you need it for phono, just sell it and buy an NAD phono. THey are cheap. Go with the Lex only.

I have a similar situation with an older Rotel processor and Denon receiver. I was going to try this method but then thought about the sub. I want to listen to 2.1 but also have the sub available to the Denon for movies. Any suggestions?

I have a Luxman CL38U SE and a Krell Showcase processor for movies. On my Bryston amp I hook up the RCA outputs to the Luxman and the Balanced outputs to the Krell. I just flip the switch on the amp. I've had tube preamps for years and this saves tube life on the preamp as HT pass through requires having both preamps on.
