I listened to various LP's through a bud's $700 Blue Circle BC-27 fono the past 2 days whilst I re-wired the Bugle in 2 boxes with a Radio Shack rotary switch for CD-Fono.
After I had the 2 boards in their respective boxes but before I wired the switch I compared the two stages:
BC-27 has more weight in the bass but the Bugle has more clarity in all 10 octaves, higher signal to noise and way less surface noise.
I went on to wire the switch and adapt the grounding. All is good. Very quiet. Switching with no pops. No more yanking on cables 'tween CD and Fono.
BUT , there is audible crosstalk.
Cheap switch?
Some buffer I should use?
I tore it out and am listening straight thru to the Blues Brothers Soundtrack with the volume control wide open. If I didn't have so many CD's I'd listen to nothing but Vinyl and not need the switch!
Is there a better switch w/o the crosstalk?

Crosstalk will always be there to some degree, sort of like noise.  One solution is to short the unselected inputs to ground.  Some switch designs not very good.  Some work quite well.  

I assume this only happens when there are two active sources playing at same time?  Like CD and vinyl both spinning?
