CanOpener will play 44.1 kHz / 24 bit ALAC's back natively, without any sample rate conversion or loss of bit depth. The sample rate conversion is only used when absolutely necessary — enjoy!

Hey all,   The CanOpener Studio plug-in beta is now live for you to test drive. If you use Audio Unit plug-ins, you can download it here: http://goodhertz.co/   Also, for precise EQ'ing, I think a lot of you would appreciate another plug-in in beta called Tone Control: based on the classic...

The CanOpener frequency response is compensated to an extent. It was designed to be consistent with the natural warmth that loudspeakers exhibit in a real room, but it definitely can be more noticeable on already warm headphones like the HD650's. Something like -1.5 dB on the Bass EQ @ 800 Hz...

Queue functionality is definitely on our radar — thanks!

  Thanks for the great review!   Glad you like Speaker+. Just to clarify, we're not doing anything to degrade the sound in "Off" position — we would never do something like that. On most of the phones it's plenty degraded already :)    Cheers, Devin

Whoa, this is rad!

  Hi Michael,    Thanks so much! Glad you're liking it.   Unfortunately, Apple doesn't give us the ability to create playlists, though we could make playlists locally within CanOpener itself (they just wouldn't be available anywhere else) — would that help in your case?

Hi glorkaglickflic,    I'm not a Stax user, so I can't really comment on those specifically, but I can talk about FHX. Some users describe FHX as making the soundstage wider & more expansive, while others perceive it as being narrower and more center focused. Personally, I find that it depends...

Thanks KraftD1 for the help! It's right in the middle, around ~4.5 dB.

We could definitely add this. Would you want it to behave how the iTunes crossfade behaves?

Unfortunately, this one is an Apple limitation: we just aren't given any info about what happens with the audio output when our app is in the background or the device is asleep, so we have to ask again. We know it's not ideal though and are looking at better ways to use the previously selected...

Thanks so much. Philips Fidelio X1 added to the list to test!

Weird! Please let us know if you think you've found a bug.   Will do — I didn't know there was on-ear version as well. We'll check them out.

Did you send try to send an email to us? I'm not seeing any support messages about MP3's/video files, and we haven't been having any issues with email server. Feel free to PM me here if you can't get through though.

Thanks for letting us know and for the support email as well.   While we could support folders within the app itself, iTunes File Sharing does not support transferring folders, which is why the app does not expect to see folders being used. Is there a reason you are using iFunBox instead...
