Careful, you'll have officers from operation Yewtree knocking on your door ;-)

I'd expect that using the phono outputs from your CD player to feed two amps would work fine in most cases. But there are a few possible issues:

i) If either amp has an input circuit which shorts the input to ground when the amp is powered down then there would be a problem. I haven't come across such an amp. But it's not impossible that there's one out there.

ii) If both amps have unusually low input impedances then you might load the CDP a bit more heavily than it likes. You shouldn't hurt it. But the sound volume may be reduced and in extreme cases the frequency response could be altered.

iii) If both amps are independently mains earthed then there's a risk of setting up some kind of multiple earth loop. This could give you some low-level hum.

If you can tell us the exact makes and model numbers of the amps we might be able to narrow the chances down a bit. But if you have access to the phono splitter/s then you could resolve this very quickly by just trying it. I'm assuming of course that you will only have one amp (the one you're using) powered up at any given time.

Alternatively you could use the tape loop from one amp to feed the second amp.

Regarding speaker switching, when I asked on here it was suggested I use a light switch :)

It would probably be a good idea to ensure that the speaker commons are not connected together. On some amplifiers, these are not grounded. (The Quad 303 being a case in point.)
