I got the 250 which juuuust matches my saffire, and also for using it on other peoples amps and stuff (i researched it beforehand). And when i say full gain, thats only really for when its under 14ish RMS, otherwise its too loud.
It seems to lose a bit of smoothness and clarity at my maximum comfortable volume, but the culprate is the high-mids, which should sort itself out, like what you said, with proper burn in. But, also like you said, ive always had the idea that it is a form of placebo and that it really should make much of an actual difference, which complicates things. If it ends up not making much of a difference than there might be something wrong with them, my ears. Maybe the fact that ive been stuck with poor studio sound with my monitors in my bedroom that i dont know what i should be looking for in a pair of cans.
I'll cease judgement until i give em the time, but its just bit of a worry for now. Especially since i sent a WIP to a few people and they said the mix was fine even though i thought it was shite and needed more work. Ah well.
Thanks for the help guys in the forum, and i hope you stay here and pitch in a bit crukky, cause the more established peeps the better.
