Hello! I'm looking for a good splitter to use 2 headphones with an amplifier. I wish to not lose the quality from the amplifier, is that possible? Right now I'm using a splitter (10€) that is pretty bad since I lose some quality. Can you help me please?

Hello, I'm Fabio, as I wrote in the title I need everything to enter in this beautiful world. I tried a few years ago to ask for help in an italian forum (I'm Italian), but apparently the noobs are not very welcome in that forum, so I was discouraged and I stopped my research. But now I'm here...
