Review: Highly recommend - Fantastic for switching unbalanced to balanced or balanced to unbalanced converter I enjoyed the pure sound from sony tv to jbl powered stereo.
Review: Voelt stevig aan, grote knoppen en het werkt naar behoren. - Er kan weinig aan dit apparaat misgaan. Ik gebruik het om te schakelen tussen twee gebalanceerde XLR inputs die naar een set actieve luidsprekers gaan. Als er al sprske is van degradatie van het geluid, dan kan ik het niet horen. Ik weet niet wat er gebeurt als.je van XLR naar RCA gaat, maar ik vermoed dat dit wel impact kan hebben. Beter soooet bij soort houden denk ik. Handog ding, want ik zou mog een extra paar actieve luidsprekers kunnen aansluiten ook. Voelt stevig aan, grote knoppen en het werkt naar behoren.

### ⭐⭐⭐⭐⭐ Good quality 3 in 3 out balanced/RCA selector/router box.
*by C***Y on 19 June 2019*

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.
