This is serious business!
Bought to double the jack output of my DAC/USB amp, so that I could permanently plug in my pair of powered speakers, and connect my headphones or hi-fi amp via an RCA/Jack cable if I needed to.
I was on my tenth splitter from other brands, but there was a loss of audible quality, crackling and false contacts.
I tested the 1st Real Cable product, motivated by the good comments, and I have to say that this splitter is perfect in every way, no background noise, no alteration of the sound whether on amplified speakers, headphones or hi-fi amp.
The jacks fit tightly (but not too tightly) into the connectors, so you can feel that there's no play and that it's a solid, well-built unit.
You can move the splitter and the jack connectors without worrying about sound or crackling, unlike most other splitters!
The splitter's cables are rigid, so it's ideal for resting on a piece of furniture, but much less practical for transporting. At the same time, given the build quality and its clearly audiophile side, this splitter is intended for use with rather mid-range equipment, and even beyond that, it's not crazy.
For 15€ frankly it's a bargain ;)
Surely the best splitter on the market, for a very modest sum compared with the competition, here the specification sheet speaks for itself, and when you unpack it you're not at all disappointed.
Ordered from my local shop, picked up 72 hours later, as always with LDLC, efficiency, professionalism, and a perfect welcome, and always with a 3 year warranty, the splitter is guaranteed for life (it says so on the box).
