Best way to connect 2 preamps to 1 power amp


Hi,
I have 2 preamps; 1 tube 2-channel for musics; 1 solid state pro-logic 5 channel for movies; both have RCA output. The power amp for front channel is lexicon 212 (Bryston 3bst); has both xlr & rca inputs w/ selector switch. Shall I:

1) use rca y-adapter for the 2 pre-amps to the 212
2) Use rca for the tube & xlr (w/ rca xlr adapter) to the 5-channel. Use the selector switch to change source.

Please advice any concerns/problems for any/both connections. Or any other better solutions.
Best

The best thing would be if your 2 channel preamp has a HT or Processor pass through. The other thing that will work is to connect the front channel outputs of the Pro Logic preamp to one of the unused inputs on the 2 channel pre. The only downside the the latter is having two volume controls inline.
No use in this case because you want to send the processor through the tube pre instead of the other way around.
