Thank you for testing 768kHz.
What op amps have you used as replacement?
Regarding the i5: Yes, I will probably buy them via Amazon.
And the idea with the wool is great. That way you get more closed back characteristics.
Speaking of closed back:
Do you have - by chance - the Beyerdynamic DT770...
Great extensive review!
@antalistvan1968 Have you managed to set the output to 32Bit/768kHz?
What do you think of the stock op amps?
Could you maybe also do a review of your Fosi Audio I5 in combination with the ZH3?
That would really help me to decide whether buying these headphones or not.
I am running my ZH3 over USB on WIN11.
The maximum output setting I am able to set is 32Bit, 384000Hz.
Based on the spec sheet the ZH3 is capable of the output of 32 Bit, 768000Hz.
Does this need a driver update or how can I set this up?
On my Fosi Audio ZH3 I am only able to select up to 32Bit / 384kHz as output setting over USB. According to the data sheet 32Bit / 768kHz should be possible.
Am I doing sth wrong that this is not available? Please advise.
