Combiner for 5.1 analog inputs

[bluseminole]

So this is a problem many people probably face...

My 7.1 channel receiver does not have HDMI, so I use the analog inputs for BD audio. But I have an SACD player, which means I have to switch cables every time I want to listen to multichannel music. Not convenient.

My question is this: Would it degrade the performance to use a y-"splitter" (one male to two females) to combine the signals from the SACD and BD players and run them into one input for each channel?

I have seen some of the multichannel analog switching boxes, and they are out of my price range for the moment, as is upgrading to a new receiver. I'm saving up to go high-end in a few years, so I'm being pretty stingy with my current system.

Is this a feasible solution?
