    Would you use a BitPerfect, Amarra, PureMusic iPhone app?

    I think it would be great to have a high quaility iPhone audio playback app. Your thoughts on this? Perhaps the companies mentioned in the title will see the interests or lack of interests and act accordingly?

    There are several already that purport to be high-quality playback apps, including FLAC Player, etc. But, yes, I'd love to get Audirvana or Amarra-quality sound out of my iDevices.

    I think an app that sounds better than the stock iPod app would be awesome. No amp, no cables to destroy the sexiness of the iPhone/iPod Touch. Just run and app and enjoy with your favorite cans. That's not attractive to you guys?

    Not sure what's happening when I do this but if I take a high rez file, say 24/192, and drag and drop, from a desktop directory other than iTunes, into the DEVICES listing in iTunes, effectively bypassing the host iTunes library, these music files will load into the iPhone or iPad and play. If they are in the host iTunes library and I attempt the same drag and drop a notice will pop up telling me these files are incompatible with the device.
    I'm left wondering at what sampling rates I am listening to these files when played on the iPhone/iPad. One other artifact of the "drag and drop" transfer is that the files need to be added to a playlist, using the host computer's iTunes, otherwise they are random in the library...hope this makes sense. I suspect these devices can do more than the gateway, iTunes on the host computer, allows.

    Yes, iTunes will only allow up to 24/48 files to synch, but you can drag and drop just about any rate. Others have tested output using the Camera Connection Kit (on the iPad only, of course) and it's outputting at least 24/192 via USB (I've seen others report up to 24/384, but I can't find that reference now). This bypasses the internal DAC, so it may be that the internal DAC is the limiting factor in restricting support to 24/48.

    So we have shown that we can drag and drop high Rez files into the iPhone or iPad. When playing these files using the device and headphones, is the file down sampled or is it playing at native?

    Again, I'm just relying on what I've been told - my understanding is everything is output at 16/44 or 16/48 *unless* you're using one of the digital out docks (Wadia, etc.) or the CCK, as mentioned above, as you're actually bypassing the internal DAC / analog-out at that point.

    There was a bit of a kerfuffle a few months back as one member was claiming that a very specific model of iPod (one of the Shuffles, I believe) was actually capable of 24-bit output, but that was never proven and Apple has been quite tight-lipped about the actual capabilities of the DACs in the iDevices.

    There were always rumors of Job's bona fide's as an audiophile...with reports of his owning Wilson's and a strong vinyl proponent...so it is curious that he'd "choke" these devices when a high Rez capable iPhone would be a delight and, I suspect, easily achievable at a minimal addition to the cost.

    It's a limitation of iOS. 16/48 max even for devices that bypass the internal DAC. Only exception is iPad + Camera Connection Kit. But of course there are non-Apple audiophile grade portable players. IBasso DX-100, Hifiman HM series, Colorfly etc.. which do support high-res output.

    I do travel way too much, 25,000 air miles in 8 flights in the last 2 weeks for example :-(

    However, given that my iPhone only holds 16GB, I trade off quantity over quality and have iTunes convert the music to 256AAC. I feel that in spite of my rather decent UE600vi in-ears I can live with the quality while being on planes etc. I know some purists will cry out loud reading this...

    I might if there were to be a perceptible difference in sound quality. I use an iTouch (running AIFF of course) as the front end at my garden and at my remodeling project.

    I was not aware the iPhone had a High Rez DAC...My Android has a 24/96 DAC and accepts files of that size??? Put another way, I do not consider the iPhone a serious music device.

    Paired up with the HRT iStreamer, my iPhone 4S sounds incredibly good. Granted, the iStreamer is one of the devices that has the ability to access the digital audio files from the iPhone (letting them skip the DAC/amp). It's not strictly a serious music device, no. But if you're after that, I would look for a HiFiMan device or something like that.


    If Sonic Studio could create a small device (something like a little dongle that doesn't require its own power) that could access the digital files like Algorhythm Solo, HRT iStreamer, etc... and then make an App that could process the digital audio before it went to this small device (or an App that could change the little device's processing settings) - I think it would be possible to achieve a really good music device.

    I'm thinking something along the lines of the iWow 3D. Does that access the digital files like these other devices? I know it has a DAC built into it, and there is an App that will change its processing settings (it's just rather poor quality, I have one). I would love an Amarra quality dongle like that with its own DAC (that little Dragonfly is a nice DAC the size of a USB stick, I'm sure they could do it)

    Too bad nobody would be willing to fork over the $400 it would cost, aside from enthusiasts like those on this forum.
