немного вопросов/ответов на тему CK4 с хедфая
Quote:

Thank you for purchasing our products and give comments and suggestions of our products.

Our response to your question is as follows:

1.)

- some clicking noise during high resolution playback

like static discharge or playback of vinyl rip

nearly every 10 sec is at least one...and it seems on higher resolution worse)

maybe firmware bug?

I translated with google the C4 firmware release log, and found this: "revised WAV format compatibility issues"

Re:The firmware of CK4 WAV decoding is the latest, no need to upgrade. some clicking noise may be caused by low clock frequency of CK4's processor.

High clock frequency will cause increased power consumption.We will check this problem later.
2.)

- only wav supported for high resolution playback (>48kHz/16bit) -> There is a BIG need for Flac too. (+ ape)

Re:flac high resolution playback will be supported by firmware update,But the release date of firmware update is not determined.

3.)

- no cover art during playback (folder.jpg ?)

Re:if the song embeded album tag information,CK4 will display the pic of album ,when display mode is set ID3 mode.

4.)

- the Line Out can be changed by Volume control (should be fixed)

Re: Yes, when changed volume the Line out output will be controled.

So,If you want to use the Line Out,you must set maximum volume,This was the best.

Line Out is a direct output for LPF circuit of DAC ,this can not be fixed.

5.)

- EQ is not working (can't hear a difference)

Re:then it will work when you select the EQ.In the EQ menu CK4 have no preview function.

the later firware version will add this fuction.

6.)
- the disblay for freq/bit (44.1kHz/24bit) sometimes does not change the value correctly (number is flashing?)
Re: we also found this problem,later will be fixed.
7.)
- the menu for eq/repeat/.. has some graphical bug, after close it by menu button, the part of this menu is flashing
I can find to You all bugs, I really good from that.

Re:later version will fix these bugs.soon we will release out the updete package of CK4,user can update the firmware by himself,these issues will be resolved.

I really hope that They address priority to the problem 1.) and 2.) because this player biggest function is the High Resolution playback...Maybe some kind of internal software settings (maybe reboot needed to change clock freq?).
