No static discharge. I tried several different sockets, all our grounded sockets, same effect in all, buzz sound if I touch the headphone cups.

Hello! I ordered a balanced cable to connect my Fostex ТН900 to Zen Signature set HFM
But they scare me that I did it in vain! The output power of 6.3 is greater than that of the balanced output of 4.4. I made a mistake? Should I order a cable with a 6.3 connector?

Ifi's amp play better with high impedance headphones. Not sure about current hungry headphones. It shouldn't be a problem either way. I've used 25 ohm Ananda balanced and it sounded great. It's a good amp no matter what but it's a very good amp with high impedance balanced stuff like Sennheiser's or T1.2. I wonder if it works in class a mode with low impedance headphones.
Balanced output is cleaner btw. Check out audiosciencereview measurements of ifi zen can.

Hey, can I come here for help?

I just got the V1 of this and I love it for the most part, but there are certain websites/applications that, when I open them, don't give me any sound. This includes random places like Google Meet (on Firefox) and Songsterr (on Firefox, but on Microsoft Edge it works well). I have my settings as in the attached photo.

Otherwise the sound quality has really changed my life! If I could just fix this issue it would be perfect!

EDIT: Hey everyone I seem to have fixed my problem. I had my sound settings set to the highest settings (32 Bit, 384000 Hz). When I lowered it to under 24 bit 192000, I was able to hear sound in all of the places that I had lost sound. To everyone else who might have this issue, try doing that.

You're OK! ZEN Signature HFM is a fully balanced product, so it should be used as such to get the very best out of it and both its SE and balanced haedphone outs have enough jiuce to handle your Fostex cans. All good

Thanks for letting us know and we're happy that everything works fine for you now

Hi! In which class Zen dac working with Senn HD600? A, AB or D?

And on what sound level you usually listen with HD600?

@iFi audio I have Zen Dac and Zen Can stack, when i connect them via 4.4mm balanced cable i get ground loop noise. Why is this happening ? It doesn't happen with single ended RCA connection. I thought balanced connection was immune to ground loop issues.

I'm pretty sure that it's a class AB design, but I'd have to double-check this.

If I may ask, what sort of noise is it? And do you sense any static upon touching their enclosures? Also if possible, is there a way you could check whether your 4.4mm cable isn't the culprit? Thanks!

Thank you for the reply. Unfortunately i don't know how to check if cable is the problem but i saw another user with the same problem in another forum which makes me believe it's not the cable.

It's a constant buzz on the right channel and if i touch to enclosure i can also hear coil whine. RCA connection doesn't have this problem, i only hear noise floor with RCA cable, no odd noises. If i connect both cables (RCA and 4.4 BAL), buzz noise disappear as well.
Also volume knob makes unwanted noises too unless i touch to enclosure at the same time. Volume knob coil whine is irrelevant to BAL connection buzz.

1- 4.4 bal= constant buzz
2- RCA= clean, only noise floor audible with sensitive iems at high gains which is normal.
3- 4.4bal + RCA= clean again.
4- Volume knob makes coil whine and scratchy noises. Doesn't make coil whine if i touch to enclosure at the same time while adjusting the volume.

I'll ask about what might be the cause of this issue and specifically what 4.4mm has to do with it, but in the meantime please feel free to let us know about it here: https://support.ifi-audio.com

Hi! In which class Zen dac working with Senn HD600? A, AB or D?

A small update: ZEN DAC operates in class B and ZEN CAN is a class AB design that up to quite high output is biased into class A. Thanks!

Just pulled out a charger and plugged into Zen DAC and it brings a wider soundstage and slightly more volume/power to my HD650! Amazing stuff!
