Amp switcher

I have one and it works quite well. I have an Onkyo 875 receiver and a Cayin A88T tube amp connected to it. The switching is automatic upon powering up the Onkyo. No degradation in sound whatsoever. I use the Cayin for 2 channel listening and the Onkyo for home theater. Solved my problem of sharing the mains between the two amps.

I use Audioquest Slate speaker cables in my setup. The Niles is triggered by a 12v switch that you hook up to one of the amplifiers. When that amp is powered up, the switch is triggered and the load goes from that amp to the speakers. If you don't power it up, the load from the other amp goes to the speakers. I have it hooked up so that turning on the Onkyo triggers the switch. When I want to listen to 2-channel sound, I power up the Cayin and leave the Onkyo off. When I want to watch a movie, I turn the Cayin off (if it is on) and power up the Onkyo. It works quite well after you set it up and I did not notice any degradation in the sound from either amp.

Once I forgot to turn the Cayin off and powered up the Onkyo. The only thing that happened was that I lost the sound coming from the Cayin. When I realized what I had done, I powered off the Cayin. No sweat. Nothing exploded and nothing was damaged. I suggest you do the same. Have the SS amp be the amp that gets switched and the tube amp be the one that is the default.

Have fun!

Sorry, you are right! I am using the SPK-1 (with automatic switching and the larger binding posts). Didn't mean to confuse everyone. I did not pay close attention to the mdel designation in the original post and assumed you were asking about the SPK-1.

I use banana plugs to connect to the speakers, the Niles and the amps. The unit sits on the floor behind may cabinet, but you can wall mount it, if you want. I got mine from OneCall and got the 12v DC trigger from them when I got the unit. I've been using this set up for over a year w/o any issues.

If you are concerned about the tube amp, just make sure you turn it off before switching. You would do that anyway, so it's not that much of a hassle.
