if you have a ps2 it doesn't matter if they are internally powered...you have your 48v's right there. also you could easily go to Guitar center and match them yourself in the store if they have a bunch of them...which they usually do. i matched mine in the store....found 2 that were only ~2db off. as for the quality issues i always found them to be great mics, but then again i'm biased cause i used to own them. i always wanted to get the hyper caps but upgraded to the TL's outright instead
like i said though it all depends on what you like. if you like the akg sound you know what mics to get. c1000s > 390s > 480s. all great mics. people talk very highly of the 480's especially the hyper cap and there are tapes out there to prove it. there are also some fantastic oktava tapes out there as well
