For the fun of it I tried a 3 meters i2s, I still got music. I did not spend too much time checking the SQ though...

I have bought few flat ribbon cable for test, it is worst than the normal web cable, then I cut it ,fought it is each two wires intertwist configuration .

 

I have try the longest I2S transfer  with 5M cable still working, a bit worst performance by instruments test, slight worst on sound.

Sorry Kingwa I had mixed it up and misrepresented your i2s cable connection suggestion. Thanks for correcting it.

If the cable is real flat ribbon configuration will be better.

 

I want to practise applied shield cable X4 to build the I2S cable later.

or one option to build a flat ribbon is to ripping apart a regular CAT7, lay them flat as a ribbon, tape them, then put foil around them ...

Hi!

I am looking for I2S input Board for my dac.

In this page I found this description:

 

"this little board allows for two extra selectable I2S inputs in addition to preserving the original I2S line"

 

Where can I buy this little completed pcb?

What is the price?

 

Best regards,

Hey all,

 

Was wondering if anyone with the Reference 7 (not the 7.1) could elaborate on how long they leave their unit powered on? Does anyone leave it on 24/7?

 

I picked up a Reference 7 second hand a few days ago and have noticed the manual isn't actually available on the Audio-GD site -- it's just got a diagram of the internal jumpers that can be used to bypass oversampling etc.

 

I've never really needed to leave a DAC on 24/7, but I've noticed the Reference 7 needs a fair amount of warm up time before it's sounding best. I am concerned since it runs much warmer than my previous DACs (Centrance DACMini + M2Tech Young) and I also read somewhere in this thread that apparently the manual says to operate it for no longer then 8hrs at a time...

 

I actually left it on for two days when I first got it. It was just warm to touch. While it's obviously still working fine I am a little concerned if leaving it on 24/7 is not considered appropriate, since the warm up time really is fairly lengthy...

 

I've emailed Kingwa for advice but not heard back yet. Appreciate any input in the mean time. :)

 

Cheers

 

EDIT:

 

Kingwa has advised 24/7 operating is OK as long as it is not too hot, but to restart the unit every 5 days or so.
