David has already explained it. EQ is applied to the digital signals before it is converted to analog. I really don't understand what is so confusing. I can use EQ on a computer too with any DAC of my choice. You can't bypass the OS. How in the world would the application playing the music, using your playlist, skipping tracks, etc work?

I've used all my iOS7 devices on the following dacs and could eq all of them: Reaonnessence Labs Herus, Leckerton UHA760, Cypher Labs Solo -dB and a Violectric V800 with a Matrix usb/spdif converter between them.

I think david is the honest one in the bunch. When I bought mine it was missing a part . I ordered mine form tod the vinyl guy. Who is also a good guy. Well the point is David helped me quickly. And we talked at length about apple and the interface . I could here in his voice the apprehension of what he was saying. And the fact that apple simply controls there product and there is nothing he or others can do. In fact he is the only real honest guy in this. As other peoples interface makes bogus claims of high resolution. So be nice to cypherlabs. And I am sorry I brought this up. I was just asking a question as I new what the answer was last year , but maybe with new IO systems maybe it changed . Next I will say anything beyond red book meaning 16/88.2 is a waiste with IEM,S as the resolution of them is not enough for you to accurately decern the better sound with. And I know the golden ears here will say they know , and I'll bet they hear a flea fart at a twenty feet too. So let them grip . For the rest of us meat mortles we do not. So for me it's more than fine and sounds really good. I only posted to inform people and to save space on your phones. So take the hi Rez flac no compression and down sample to use on the iPhone .

I hope this helps and I did not mean to stir things up. David is an exceptionel guy. And deserves the utmost respect for his great products. Its honest people like him that get kicked for being honest while the other people just post claims that are lies clocked in truth.
Ps add on. As for the EQ in some of our apple products. If you turn it off , it's off and I really prefere to have such a feature .
Now beyond this the io s of the apple products has effects on our transport sound weather we want to know or not.
The different iPhones and pods or what ever I am very sure sound a little different there is no perfect or pure. Not with apple or any product they all add or takeaway something.

Let's enjoy all,our product s as I do. It truly is a hi end product you can put in your pocket. That is pretty coo. To me.

Wierd. My link to cypher labs blog page where they state the bitrates seems to have been deleted/moderated.

My concern is Cypher Labs’ marketing of the CLAS, which I don’t quite grasp, i.e. taking out the digital audio stream bypassing the inner logic of the iPod which is supposedly proven by the fact that the volume can no longer be adjusted through the iPod. Would that mean that the volume adjustment isn’t part of the OS but that the EQ is? How can the EQ be applied to an encrypted bit stream? I find things like this confusing and interesting and can only congratulate you that you don’t, or maybe you simply don’t care, which I can respect, but then you need to be clear about that.


Stating that “David has already explained it” implies that you consider David’s reply to be complete and axiomatic. To me it isn’t, and the reason for that could very well be that I lack the necessary understanding and background of how digital media work in general. What I’m looking for is an in-depth explanation in a clear language preferably accompanied by a diagram. If this explanation can be applied to computers as well, then that is an added bonus. Now, I’m not claiming that CypherLabs owns me such an explanation but being in the business I would consider it an excellent good-will opportunity for Cypher Labs to clearly explain this.


Also, I’m not alone; we seem to be at least a few people confused about this. More than anything it is an interesting topic. After all, to many of us IEMs and sound is a passion, and we simply seek knowledge so that we can make the right decisions about what gear to buy and use. It is really all very simple!

Why not ask other iOS DAC makers the question. Why is david the one to explain. All the others are misleading you so you beat the drum to the one guy who speaks the truth. As for volume it is dismantled in code only. Remember the same code is for all,iOS users. Here is an example. All,iOS phones do the same thing when a call comes through. You know what it does. It rings and you can answer but they cannot hear you. I have three different companies all the same.
It is code that apple will not allow a chnge for. It is why AK did a work araound and tired a Bluetooth connection. Well it works sometimes and not with all models. I do not represent anyone here but myself. Ask a question and get an answer
But no one here owes you an essay on anything. And already told you there are ,maNy happy people here why do you want to spoil the party. So send some emails to the other guys and I am sure you know who they are.

I am not trying to be rude but you are asking for details most likely no one has or matters.

It seems to me your hang up here are the words encryption and decryption, which have nothing to do with decompressing mp3/lossless files. Performing EQ on an audio stream is done in the digital domain preprocessing, which just means before going through the DAC and amp.

The OS of any DAP is decompressing the mp3/lossless files and will also control any gapless functionality. A DAC does not do this. You have to have that functionality performed before passing the digital stream to an external DAC.

What Apple does is encrypt communication to external devices. What Cypher Labs devices (and the Fostex HP-P1 and maybe a few others) do is decrypt this communication in order to perform a digital handshake and control certain music player functions. Basically the verbiage you seem to have a problem with is CL telling you they are licensed by Apple to decrypt the iAP protocol. One thing this allows is charging of the iPod/iPhones battery. In previous iOS versions it used to allow more functionality and control of the player but my understanding is that Apple has limited much of that with the newer lightning connector change over. Only an authorized MFi developer could tell you what all Apple allows you to do with their certification and iAP protocol through digital usb.

Once upon a time, this digital handshake was the ONLY way to extract digital audio from iDevices. With iOS 7, Apple has allowed usb hosting on all iDevices running iOS 7 but this can only be performed using the proprietary Apple CCK cable, and the DAC’s usb connection must be using UAC1 AND draw less than 20mA. If the device draws more than 20mA, iOS will not play with that device. In some cases you put a powered usb hub between the iDevice and the DAC and it may or may not work. In my case I’ve used a Matrix USB/SPDIF converter in between my iPad/iPhone and a desktop dac and it works as well with the CCK cable and digital coax.

The problem with these configurations is that they can and will drain the battery of your iDevice much quicker. By being MFi certified and given access to the iAP, there are probably many restrictions and/or requirements of how you handle these situations, and keeping an iDevice charged may be one of them- to keep the user experience at a level Apple deems necessary. Seems most licensed Apple compatible devices charge the battery.

The volume bar is an interesting topic.

 

I had a similar conversation with Centrance prior to their release of the Hifi-M8.

I wanted the volume bar disabled/invisible as it gives the sense it is properly synced, also pleasing to the eye.

(They disabled the volume bar and also made it invisible).

 

When I had my Fostex hp_p1  it showed the volume bar(but didnt function), then I got my Fostex firmware updated and the volume bar was not visible.

 

----------------------------------------------------------------------------------------

CONFIRMED idevice DAC/Amps with no volume bar( 6/2013):

Fostex hp_p1 running newest firmware, (although with older devices such as the touch2G the volume disappears on last hp_p1 firmware).

Venturecraft products(by head-fi`er mthefirst who has all their idevice dac/amps).

Sony-pha1 (confirmed by head-fier dpmalito)

 

you can read the dialogue summary here:

http://www.head-fi.org/t/622939/the-centrance-hifi-m8-thread/2325

 

___________________________________________________

 

Hifi-M8 with Touch5G screenshot (As a contribution to bitrates conversation-not a fighting comparison), need to be running latest OS with Flacplayer for screenshots.

The Hifi-M8 is running at 24/48 (Using a 24/96 file).

 

Maybe someone can buy the app and check out the CLAS with various bitrates.

Thanks, must have just been Tapatalk again.

I had the venture craft. And the volume bar was there but disabled
And I have the vamp VErza and the volume bar is there
But disabled
Chypejer labs volume bar desabled but visibl

The point I made before is those devices tell you the max
But not the limitations by device.

I thought he was quite explicit on his blog,

http://www.cypherlabs.com/bit-rate-frequency/

 

but I understand the confusion with how some of these devices are presented, when they emphasis the maximum resolution in their advertising.

post #1604 of 1650
Yes exactly. I feel so bad as I am the a h,, who asked the question.
I new the answer from before and just wanted
An update and I started this whole mess. I should just emailed
David. This is why I am sticking it out in this thread.

I have a question for experts in CLAS.

My rig consist of Desktop WinAmp -> CLAS -db (balanced) copper 7N OCC interconnect -> SR71b -> Denon AH-D7000 (Single ended) stock cable (7N).

When I play flac/mp3/alac files I notice no differences except maybe bit emphasized in the bass boost, maybe due to copper interconnects.
If I detach CLAS I noticed no sound quality differences when playing classical/jazz/rock/pop music. ( Desktop -> SR71b, hence using the computer internal built in DAC)

Am I doing anything wrong here ? it seems like CLAS -db doesn't bring any benefit in terms of SQ.

Please help, thanks in advance.
