First i have to say thank you for all the answeres! I did not expect to get so many infos in such a short time.
I spend some time to check the suggested devices.
@ miserybeforethemusic
After a bit of resurch i think i found the right one for me. The Qudelix 5k. It has everything i want
(exept the price. but i will not be happy with the cheaper ones, so i have to make it work).
I really like that i can use the EQ even when using the LDAC code. And a decent App is also worth a lot.
But i can not find any info which Windows versions are supported. I ask because i use a old Win 7 PC at my workbench and it would be nice if i could use the Qudelix 5k as a USB DAC when i am soldering /repairing stuff. But i have another question.
Please correct me if i am wrong. To use the 2,5mm outpute i would need a completly new cable for my CCA CKX (balanced cable?).
Because the standart 3,5mm cable is using common ground and 2,5mm not, there is no way to use a adapter from 3,5 to 2,5.?.?
If i am right can someone point me in the right direction to a decent cable that does not cost as much as the Heapphones
?
