Review: Good quality 3 in 3 out balanced/RCA selector/router box. - This is just a simple source and output selector. I am using it to route input signal from my two DACS; a Topping D30 and (not pictured) SMSL SU8 to my various amps. I'm considering getting another 2 in 1 out so I can connect the output of 2 amps and do quick a/b comparisons. It takes up a lot of space because it has 8 balanced connections and 4 RCA connections on the back. Knobs feel sturdy enough. This is an entirely passive source/output selector so, aside from any potential signal degradation you might get from the quality of the internal wiring this should be a fundamentally neutral device. As far as I can tell it's transparent and has not degraded the sound quality at all and made it much simpler to route inputs to desired outputs. It's a light weight unit. It's not built like a tank but, unless you're extremely hard on things, this should last you a very long time, and because it's so simple in design it should be very user serviceable if one of the selector switches, or input connectors ever fails. You'd just have to be relatively handy with a soldering iron. Highly recommend.
Review: Works well, just a simple solid product. - simple, cheap, hard to get wrong. XLR outputs are the bomb. Again, hard to get wrong, but for me had just the right inputs and outputs for my config.

simple, cheap, hard to get wrong. XLR outputs are the bomb. Again, hard to get wrong, but for me had just the right inputs and outputs for my config.

### ⭐⭐⭐⭐ Single-ended switching, connectors, box. Period.
*by M***E on September 22, 2024*

Keep in mind this is -not- a level converter or single-ended to balanced converter, which would require transformers (and still be passive), or electronics and power (and cost more): Description could be more clear (not balanced XLR), but if you require single-ended only switching, and mixing of connector types, this will likely do the job.
