Can you clarify what portable music player(s) you use for reviewing IEMS?
In the opening thread post you say
On-the-go listening is done using a Cowon J3 and HiFiMan HM-901 portable players. A wide range of tracks in FLAC and mp3 file formats is used. Critical listening is done via an optical-fed iBasso D10 and the HiFiMan HM-901 using only WMA and Flac lossless files.
Is that still the case?
One might argue that neither of those devices are really very commonly used and certainly the J3 is not really on a par anymore with current devices.
On top of that, what settings do you use on these devices and what volume do you play music at?
I ask this really because I personally use a Samsung S3 rooted with Boeffla Kernel and Viper 4 android DSP app.
In this scenario, how can I know how these IEMs you are reviewing will sound from my phone?
No offence meant at all, but perhaps this thread might be a bit like the equivalent of watching cookery programmes when you don't own an oven.
I use all of the sources listed. Unless your DAP has something seriously wrong with it, like high output impedance at the headphone jack or a ridiculous noise floor (both of which were an issue with my old Android phone, for example) you should be getting sound that is close to what I can get with the HM-901 or one of the mini USB DACs. I personally don't think the HM-901 is miles ahead of a decent "mainstream" source like the iPhone 5 so again unless you're using something with a problem, the source as a variable is almost negligible compared to the actual differences between IEMs, or even different eartips. This is just my experience, but apparently I'm not the only one who feels this way - see here for example: www.head-fi.org/t/709479/multi-review-hifiman-hm901-fiio-x5-sony-zx1-hisound-studio-3rd-anv-iphone-4
Obviously if you use a DSP app or an equalizer results will vary.
I don't mean if they fit the DN-1000, I mean the bore size in respect to the driver? I find that tips with openings narrower than the driver causes harsh treble which is why I hate the stock white tip, but really like the Gray ones where the opening is as wide as the driver. For the tips you mentioned and the hybrid Sony's, how wide is the opening in comparison to the driver?
Ah, no. In that case the stock gray tips are still better. The closest I have to the bore size of the gray tips in a size that fits tightly on the DN-1000 nozzle are the MEElec A161P tips, but they are thinner and more flexible/flimsy.
I’m not sure. Definitely no plans at this time but maybe in the future.
