I am completely new to quality personal audio equipment and after a bit of searching and impromptu research, I have narrowed my choices. First off, the use will be for personal home audio use in a fairly noise environment while listening to music, movies, and occasional video games without the need for a mic. I am eclectic when it comes to musical enjoyment. I listen to whatever strikes me as at the moment including classical to dubstep. Bass is important but it will not be the driving factor as much as clarity and "smoothness". Second, The equipment will be employed in a large open area with kids present and a separate tv in the background so closed back is preferable but not noise canceling. I want to be on average 12' to 15 feet away from the source and any wires will be secured against a wall. Third, my budget limitations are around $300-350 for audio gear. I figure $120 for headphones and 100 each for DAC and AMP, I have been eyeing the Modi and Magni combo. The main selections I have considered are as follows. Sony MDR 7506, Shure SRH440, Sennheiser HD449, Audio Technica ATH-M50. Any other suggestion are welcome of course. Any recommendations for places to audition these pieces around the Las Vegas area would also be appreciated but I have little choices it seems. Thanks in advance for sharing your experience.
