nice... will give it a green light. after reading up so many reviews and asking around.
Does anyone know if the Roxannes have the fullness and weight in the bottom end as the JH13Pro does? My longtime favorite was the JH13Pro because it had the perfect bass weight/punch for me, but I always desired a little bit for clarity. I just bought a custom set of Roxannes, hoping that I'd have the JH13 bottom end, with a bit added clarity and sparkle. Is this an accurate description of what I have to look forward to with my Roxannes?
Trying out the new Moon Audio stock cable, I purchased the Black Dragon cable initially because these were not yet available but the Black Dragon was a bit too dark for my taste, even after burn in. A lot of Angie owners love them so I suppose they just aren't well suited for the Roxanne due to the extra bass drivers. So far the sound is more transparent, the main difference is there's less bass and that's great because I didn't have a problem with the rest of the spectrum of the black dragon. For those that are unaware JH Audio had trouble securing reliable cables fo r the siren series but it wasn't just that, I noticed a decrease in sound quality compared to the original cables that came with my Roxannes that I purchased over a year ago. In fact they never sounded quite as good with any other cable and that's why I've been on the hunt for a good replacement. Some Roxanne owners probably don't even know how good the Roxanne is supposed to sound because of this. I can guarantee that if you purchased your Roxannes within the last maybe 5 or 6 months they don't sound as good as they could if you're using the old stock cable. I'm going to let these cables burn in an see if they open up a bit, if not then Moon Audio has Siren Series Silver Dragon cables coming to market soon and I know I will love them. I used to go for the Twag cables when I used my JH16 pro so I love that open airy silver sound.
Any idea of the timeline for the silver Dragon cable?
(I posted this in the Fiio X7 thread, but figured I'd post it here, too). Apologies for the dumb question, but what spec should I look at for determining whether my DAP has enough power to drive my JH Roxanne CIEMs? Right now I'm using a Fiio X7 DAP (w/AM1 amp module), and I'm wondering if it's not enough power. I tried connecting a Fiio Mont-Blanc E12 amp, and it seem to open things up on the Roxannes, so maybe I need more power?
When looking online at portable headphone amps, I see specs like "output power" listed in mW, Vrms, and then things like "output impedance", "output voltage", and "output current". Which should I look at to figure out whether it's enough to drive the Roxannes?
Thanks!
You don't need to worry about anything except output impedance. Choose an amp that has the lowest output impedance you can find, the higher the output impedance the worse BA iems will sound. All other values are practically irrelevant, roxannes (and pretty much all BA iems) are extremely sensitive and you can easily blow out your eardrums even with a weak amp.
Thanks for your help. Right now I'm using a Fiio X7 DAP, which I believe has an output impedance of 0.2 ohm. I was looking at upgrading to something like an Astell & Kern AK240 DAP, but that has a listed output impedance of 2 ohm. Does that mean that my Fiio X7 will do a better job of driving my JH Roxannes than the $2,500 AK240??
How is the fit on the universal version? Currently using the UM50's which has amazing fit, not ready to do CIEM's yet or buy used ones to refit either.
