Hello ,
I am from India. Today I accidentally bumped into this thread. I have bought Nokia E6 recently and after reading replies here I bought the OTG cable.
It works perfectly with E6.
I am using Purepiper DAC A1 with USB-S/Pdif converter as my DAC and Marantz pm 6002 as amp. My speakers are DIY open baffles.
I hope this helps few more people like I got help from this thread.
Regards
