I believe I can help you out. I started my journey with with the S4s a few years ago (and I thought $75 was expensive...HA! Head Fi proved me wrong). I'll try to help you out based off of my experiences. My trip by the way was Klipsch S4 -> Shure se215 -> Westone 3 -> MEElectronics M6 Pro -> RHA T10 -> Noble 3U so far.
I would recommend that you don't get the se215s or the W3s if you enjoy classical and electronic. se215s have some of the worst sub bass extension, bad clarity, and poorly extended highs with no sparkle. Mids are decent at best. Westone 3s are excellent detailed IEMs, but they somehow managed to clearly deliver the music with no sense of enjoyment whatsoever. It is more of a "that was a really clean listen" than "that song was SICK" if that makes sense.
For under $250, I would suggest checking out RHA T10s (as you already have), Vsonic gr07, sennheiser ie80, DJE 1500s, and ATH CKR9. Other people will be able to give you more recommendations.
Honestly though, I highly doubt anyone has found an IEM under $200 that they are satisfied with (and I mean legitimately satisfied with). You'd have to hit at least $400 I think in order to find an IEM that has no caveats at all.
Oh yeah, welcome to Head-Fi, and sorry about your wallet
