I'm looking at the amps listed on the site and am making a list of what to try. Being a noobie to amplifiers, I'm a little confused as to which amps allow you to plug in headphones and which ones do not. The specs on a lot of the PRS amps identify 8, 16, ... ohm outputs. Would these be suitable as headphone jacks if the resistance of the headphones matches on of these?

Thanks in advance. I'm liking the demos I see of the Sweet 16.
