I had soldered together something myself before, but had some issues. Decided to cut all middle ground and went for something that seemed reliable. The build quality is absolutely excellent, with a solid metal chassis that feels like it can handle a lot of use. The signal splitting is clean and transparent, with no noticeable loss in tone or volume. I also appreciate the galvanic isolation, which has effectively eliminated the ground loop hum I was dealing with. The phase inversion switch is a nice touch and has come in handy already a couple of times. Highly recommended for anyone needing a dependable stereo splitter!
