Upgrading from RE-400 ... shure SE535 LTD or InEar StageDriver 2? other?
This is a question for ljokerl or anyone familiar with the IEMs mentioned below, if you are kind to help me out on deciding the upgrade path to take.
I have the RE-400 and also the Sony XBA-3i and I have been enjoying them for 1.5 years, but I am ready to upgrade to the next EIM with an clear improvement in SQ. Budget in the range of $400-$600 but I could go all the day to $1200. I am looking for a well balanced IEM that improves the sound signature of the RE-400 in the following areas (see below). Please note that most of te use will be on-the-go playing with iPhone 5 or future iphone 6 when I travel (don't link to carry amps, etc)
1.- Improved soundstage: I like out of your head soundstage
2.- Improved instrument separation and imaging: I love when the music has nuance to separate the instruments in 3D
3.- Bigger bass slam, I don't necessarily need deep sub-bass but I love bass texture and impact without affecting other frequencies of the general tonality of the headphone
4.- Extended highs, a bit more extended than the RE-400 but without going into the harsh and silvant highs, so needs to control the HF
5.- Rapid dynamics (good PRaT): i listen to moderm music, mostly rock, indie, electronic, vocals, etc, so I need an IEM that can keep the fast pace as needed.
Regarding the budget, I may consider even high end EIMs (e.g. Shure SE846) if everyone agrees that it is is a class clearly superior but I would rather try to be in the $400-$600 price range if feasible.
I tested the Shure SE-535 Limited Edition (Red) and I liked it but it fails to have great highs. Still it is enjoyable juts feels overpriced for $550 in the USA. Give the review from ljokerl on the InEar StageDriver 2, it seems that this IEM would be improving the RE in all the areas mentioned, but as I cannot test it, it is hard to make a decision.
BTW, yesterday I had the chance to test the high end Shure SE846 and the AKG K3003i. I was utterly impressed by the Shure SE846 (with the white/bright filter on to enhance HF) more "real" sound that the AKG. If it would be more comfortable I would have bought it on the spot. I was so impressed. The bass, kids are perfection, extremely well balanced EIM and very musical, more so that the AKG K3003i.
Thanks much for your advise.
