heres my problem i have a audio amplifier and a surround sound amplifier in the one room with the one pair of speakers. the only way i think it's possible to have both is to have two sets of cabling and change them depending on what amplifier is being used which will be somewhat inconvenient and maybe slightly risky if the wrong amp is turned on by certain users.
does anyone have any other ideas? if a ultra high quality speaker to 2 amplifier switcher exists this maybe be a option though in my research so far i haven't come across one.
cheers

I could envision a very old-fashioned (and neatly assembled) switching unit using electromechanical relays and a time-delay relay or two (all switched with DC, to avoid potential interference, of course), which would have an "Off-A-B" switch on the front and appropriate connections on the back, to power down one amp, then switch the speakers, then power up the other amp. Components could be shielded from one another to an extent commensurate with the individual user's degree of obsession. If indicated, individual relays could be placed within the chassis of appropriate components to keep signal paths shorter. The most rewarding part would of course be sourcing all or almost all of the components from surplus providers or basement junk. And as regards the "loudspeaker switching" thread that's been running recently, there would be no need for fancy relays, as the speaker switching would be accomplished with the amps off. Also, if well designed, it would be nearly "idiot-proof," which I have found to be a key requirement before I allow family members to operate any of my "simple" equipment (family can be diabolically ingenious in finding a system's Achilles heel).

as i learned in the army, no equipment is "soldier proof". actually the simplest solution here would be a panel with a 4PDT center-off switch. or you could get a factory made speaker switch box, like the ones sold by MCM, and use it to switch between amps rather than switching between speakers (or get one for pennies on the dollar from a music store or stereo shop that's going out of business or downsizing their store display). myself, i would keep it simple, since simplicity usually translates to reliability as well. now if it were 2 amps and 1 complete set of surround speakers+sub, i would begin with relays (which requires a source of +5 or +12V)
