My SRH440s and SE215s are broken and I'm looking into getting some new IEMs. I'm focusing on the SE425, and I'd like to hear any kind of comparison of it to the SRH440. The SE425 is 3x the price and I obviously expect it to be much better, but being an IEM, will I be losing anything (such as soundstage, separation), or will the quality increase due cover all the bases? If anyone has tried both, I'd love to hear some short comparisons; the SE315 is also an option, but reviews on it that I've read have been mixed. Thanks for reading and for any responses.
