I will check mine in the morning. Now I know it disables the volume. But maybe the EQ looks like it works but does not change the sound. . But my question who has not been answered is the bit and resolution limits ?

No, just connected to a fully charged iPod classic via the USB to 30 pin connector.

I just tried my 1st setup: CLAS SOLO + last Gen 16gb Nano -> EQ has impact (I'm shocked)

I'll try the other setup later (Theorem + older generation Nano)

Are you using an iPod or are you listening through your computer? If you do use an iPod can you please share with us the type and generation of the iPod?

 

Thanks!

I checked it a year ago and didn't notice any change but i will check again, or check my ears yes…..  Doesn't make sense though if the clas is taking out the digital stream….?

Exactly my point! That's why I've asked David Maudlin to explain this to us in detail. I did receive a somewhat casual reply from David and so asked him to be more specific. However, so far he hasn't replied. If I haven't heard from him by tomorrow I'll relay his only reply to me. One thing is for sure, it is not taking out the pure digital stream directly from the storage device on the iPod. It goes through the iPod's operating system first.

Exactly, and that's why I feel Cypher Labs needs to explanation what the CLAS exactly does and does not.

Theres a post on the Cypher Labs webpage/blog that answers this I believe, sorry cant link as I am on my phone.

Another option is people with the latest OS can try Flacplayer app as it shows the bitrate it seems.

This is perfectly normal. Why wouldn't you want eq to work? I use the Equalizer app or Canopener with any dac I've used with the iPhone. That includes dacs not make for iOS using the cck cable.

I checked for you.

I went to google, then cypherlabs blog, scrolled a few articles down.

Thanks and a big AHA. I new they were taking away our hi Rez.

With all respect, that’s a different matter. My concern is that the CLAS is marketed as ”taking the sound out digitally”. On Cypher Labs’ site we can read:


"Advanced software and the integrated processor control the decryption of the digital audio stream from the Apple device, then pass it to the on-board digital to analog converter for output to the analog output."


This gives me and obviously others the impression that the CLAS effectively turns the iPod into a storage device with a great interface, bypassing the operating system’s handling of the audio stream, DAC and op-amps. I’m not a technical person but having read the above explanation I find it difficult to understand why the EQ of the iPod affects the sound when connected to the CLAS and so would find it very interesting to hear Cyper Labs explain this in a clear language.


I did e-mail Cyper Labs about this, but feel they’re somewhat avoiding my question. This gives me the impression that Cypher Labs may be leaving out critical information when describing their product in an attempt to describe it as more revolutionary than it really is.


Hear is Cypher Labs CEO David Maudlin’s reply to me:


“You will probably get some feedback from one of the experienced head-fi-ers, but to answer your question, the EQ settings on the iPod/iPhone do affect the audio. The Solo -dB processes the USB Audio stream from the iPod, bypassing the hardware DAC and op amps on the iPod, but not the operating system. Apple does not allow connected devices to use the iPod as a mass storage device, meaning the iPod's operating system still is in charge of the audio deliver. The audio in this case is the higher resolution USB Audio. So it is really the best way, because you can set the EQ to off or use it as you like, while receiving 16 or 24 bit audio (depending on the iPod). We also have a blog and you can find a topic there on frequency and bit rate that you might find useful.”


As I didn’t feel David Maudlin’s reply fully answered my question I sent him the following reply but so far it went unanswered:


“Hi David,


Please excuse me for being insistent, but would you say that my attempt of describing the data flow from the iPod to the CLAS is correct? If not, could you please elaborate and/or correct me? As I said, once we're done I would like to relay this information to Head-Fi as I'm sure there are several owners and potential buyers who would want an as accurate description as possible. Thank you!


So...


‘So, if I get this right, the data bits representing the music on the iPod’s storage device is read and decompressed by the iPod’s operating system and possibly also manipulated by the iPod’s operating system’s EQ before being sent to/read by the DAC of the CLAS?’

 

Is the EQ applied to the encrypted (compressed?) audio stream before being decrypted by the software and the integrated processor of the CLAS? I would really appreciate if you could sort this out for me (---) Thanks!"
 

If I do hear from David again I’ll let you know.

Umm guys, not to sound like a smart arse but nobody on here noticed this until now?!?! If you take an iPod Classic and compare it to a iPod Touch hooked up to a CLAS rig you'll notice there's a difference in sound due to the players each having a different default eq setting. If you hook it up to say a laptop or desktop again you'll notice a difference in sonics compared to the iPods but no difference in sonics between the laptop and desktop. If Cypher Labs was advertising the CLAS as falsely bypassing the DAC/amp in an iPod/iPhone I guarantee you Apple would have put a stop to it ages ago because the product is using Apples certification. A lot of people would consider having a digital audio feed with eq capabilities a positive thing and not something to become worked up about.

I'm not worked up about it, I'm just interested to know how the EQ can still work when bypassing the dac & amp in the iPod. Just because it is part of the OS?

I'm a big fan of CypherLabs products and I love their sound, it is high level for what I am concerned

x2, as simple as that.

Just a wild guess but probably you have guessed right, the eq is probably part of the OS

The funny thing in that case is that the EQ must then be applied to the encrypted (compressed) audio stream since according to Cyper Labs "Advanced software and the integrated processor control the decryption of the digital audio stream from the Apple device". I don't see why this should be so difficult to explain unless Cyper Labs has something to hide.
