When does one need a headphone amp? I have some Shure 1840s, which are great, but I’ve read about headphone amps and want to be sure I am getting the most from the cans.
I have a Casio PX310 digital piano. When jacks are inserted into the (quarter-inch) line out sockets, the onboard speakers are not muted. They are muted when headphones (or a jack) are inserted...
When I sit at my listening position, at the apex of an equilateral triangle with my monitors, everything sounds OK. When I shift my head things that were panned centrally move immediately to the side, and seem to come just out of that one speaker. Is this the way it’s supposed to be?
