If y'all want to have some real fun; just bop on over to some of the headphone forums. In that arena the ultimate is to have a different set of phones and source and amplification and interconnects to cover all the bases....individually!!
Like: these phones, and this amp, and this source, with these interconnects for "this" kind of music.
For "that" type of music, use these phones and this other amp.
And the amps, with miliwatt outputs, cost as much as amps with megawatts! It's nearly nuttso!!
The key words are "complementary" cans. Such as "Grados" for rock and "Senns" for classical and "AKG" for most everything in-between!! They all sound different but supposedly complement each other with the type of music being listened to!
The other word is "Synergy"! This amp works with these cans but not with those. And those cans work with this amp but not with that.
They even have "for sale or trade" parts of the forums where folks can swap around electronics and cans at minimum cost until they find what works best for them! It's pretty cool really.
And break-in with this other type of transducer is the generally accepted way of life.
I tried to get phones to match my Axioms; but many of them try to get phones, and amps, and source devices, and cables, to match each music gender!!
....but, ya know, they're havin' fun too!
