Balanced audio switching

My Oppo BDP-95 connects to the single balanced analog input of my Cary 11a processor for stereo. I want to connect my Sony XA5400ES to that same Cary balanced input. Only one player at a time would have an active signal. Can I use a $25 Y cable from Blue Jeans or do I need something like a $190 Kramer box? Can both players be powered up even though only one has output?
