RCA 4-Way Bi-Directional Audio Switcher Splitter, 1 in 4 Out / 4 in 1 Out Stereo L/R Sound Channel Audio Switch Selector Splitter Box with Remote Control for Speakers Headphones Amps (Black)

I’ve been going through a phase of trying different vintage preamps out. I was wanting to find a solution to where I could just push a button from the comfort of my chair and switched between preamps(using the same power amp) and this is literally perfect. It doesn’t color the sound at all. The remote doesn’t come with a battery it’s one of those CR2025 or 2023 batteries. Anyway, it’s so amazing to be able to just switch between 4 different preamps without having to get up and swap around wires and stuff. This is great if you had multiple amps and speakers going off the same preamp you could switch between them as well. I would give this thing 10 stars if I could it’s made testing out equipment and comparing receivers and preamps a dream. For example in the picture I am A/B between a Yamaha CX-830 and Denon DAP-2500 preamps using the Eversolo A6 as the source using Y jacks to each input on the preamps. The amp is a Denon POA-2400a. The Denon preamp sounds better than the Yamaha if you’re curious. It also sounded better than an adcom and Parasound preamp I tried before. This old high end Denon stuff is no joke.

I really wanted to like this, but I can’t.I immediately put it in my system, replacing my passive switcher, and noticed that the high end was cut just a bit. After switching back and forth between this and my current switcher, I came to realize that I can’t live with the slight sound alliteration.

I have a bunch of stereo equipment and like switching back and forth between devices. This lets me attach multiple devices and easily switch between them while staying in my seat. It is simple to set up and works well. I can't hear any difference between it in the signal path or out of it. The remote works well but I usually just leave it set to "all on" where it duplicates the signal and sends it to all outputs.

This works great. It did not add any noise to my set up that is very complex. There are plenty of wires running over this thing, so I am pleasantly surprised.

I was pleasantly surprised that it came with its own power supply, which I could not find in the listing. Also I was able to use a 2016 battery instead of the 2025 called for in the manual.

Not good want my money back
