Do you have the EF-6 and HE-6 combo now? I ask because I special ordered the EF-6 to power the HE-6 and wasn't impressed at all with the sound and in addition the EF-6 was "tested" for 24 hours before shipping yet when I got it the volume knob was completely loose and I had to turn it several times for a small increase in volume so I returned it to Fang for a refund (QC is really important for me and even more so if you are a boutique / small volume company)
No, I do not, but have heard the combo fully broken in.
There was no issue with the volume knob on the unit I used, but can understand how an experience like that can leave a bad taste in your mouth.
