My set up with ultrasone signature DU :
Source : dap AK 100 standard
Dac : iBasso DB2 balance Dac
Amp : Ortofon MHd Q7
headphone : Ultrasone Signature DJ
cable : ibasso DB2 > AK 100 use optical cable sys,concept inc
Ibasso DB2 > Ortofon MHd Q7 use DIY 4 braid solid silver core 18 awg
Sound Quality :
Ortofon MHd Q7 pair with AK 100 has not enough juice to drive headphone , I must use IBasso DB2 as external Dac to make the SQ more balance
more sweet , and better detail and separation, better bass impact and better bass body .
this one of my best sounding set up , the SQ so sweet for long listening
Please help to upload my pictures , since I upgrade to iOS 6.1 I have problems to upload my pictures
I am curious... How comfortable Ultrasone signature DJ is?
