P2 2(1)-in-1(2)-Out Amp Amplifier Speaker Switcher Selector Switch Splitter 2-Way Loudspeaker Control Combiner Box

Resolved my problem using two amps with one pair of speakers. It was easy to set up, I installed Banana Plugs on the speaker wires coming from my amps to the switch and my speaker wires already had banana plug ends. This switch will also bare wire ends. I notice no degradation of sound as the switch is a passive device. One word of caution though, if you are using a tube amplifier(s) be SURE to set the switch to select the amp you will be using before you power the amp up as not having a speaker load present can cause serious damage to tube amplifiers.

Well made, quality parts.

I needed a way to shut off the audio to a center speaker when using Bluetooth sources. (It's a complicated setup.) This did the job perfectly, and it's built like a tank. The switch on the front makes a resounding click. Not a wimpy device!

The new AV Receivers don’t play well with analog equipment so I needed to use 2 receivers with 1 set of tower speakers. I switch between 2 Integra receivers. One older Integra receiver dedicated to albums, better BASS, and the other new IAV Integra receiver for movies and CDs. A very slight difference, but happy with results. I tried every other scenario to avoid the switch, but didn’t work. I understand most high end audiophiles use separates. I’m only giving it 4 stars because I have to see how it holds up. Packaged very well and easy set up once I made 2 sets of banana speaker wires using 12- gauge copper speaker wire. I used Nakamichi banana connectors from Amazon.

WOW! I LOVED THESE AND HAVE TWO OF THEM TO SWAP OUT MY SPEAKERS AND AMPS

This switch was more expensive than others but specifically mentioned swapping amplifiers which is what I wanted to do. Now I can A/B compare two amplifiers instantly. Turns out there's astonishingly little difference between the four I tested, to my ears anyway. This could save you thousands. I'm happy I got this switch.

I have it hooked up to my main floor standing speakers, stereo and AV receiver, 10G wire and Sewell banana plugs. The only drawback is that the switcher box keeps tilting to the back, as I assume the heavy cables and plugs put too much weight on the box from the backside. I ultimately applied a double-sided tape to the two front feet to prevent the box from tilting. With that said, I don't hear a loss or diminishing sound reproduction. It's got a solid build, except for the back tilting. Before you ask, my switcher box is at the bottom and my receivers at the top of my cabinet, so it's not the other way around, which could explain the tilting as cables would be dragging down, adding more weight to the back of the box.

In my specific configuration, I have a Teac a-3340, vinyl record player, and Nakamichi BX-125 connected to the Pioneer SX-535, while the Teac X7R MkII and Dat player are linked to the Yamaha KR-730. All of these are connected to my single Pioneer cs901a.
