Hey, I have been into audiophile activities for about three years now, and bought a pair of sennheiser HD600s. About a week ago I had the "great" idea to purchase an audio splitter, so I could hear the speakers and headphones running at the same time. Turns out, it is the most open soundstage I have ever heard, even beating a pair of MEZE Elites. Wondering if anyone else has tried this, or if there are any pros / cons to it. I highly recommend it seeing has it blows my mind with every song I hear.
