Just another quick suggestion - it's a good idea to bring a notepad and pen, or a smartphone if you're a fast typer. Because man I'll tell ya - it's easy to forget every little observation of the sonic performance of a headphone, amp and all the model numbers, etc. and sometimes you end up getting your wires crossed unless you have a hard copy of your observations. It's what I do, so hopefully I'm not the only one looking nerdy.
Also speaking of appearance, it's useful to keep in mind that appearance doesn't dictate the sound of a rig (especially with the looks of my tube amp), and of course price also doesn't dictate sound quality.
