TW,
Thanks for your reply.
The sq I'm getting ,as I posted above,has a deeper base..SN-03397 ,slight dip??..frequency graph dated 9/4/2012
The pair I borrowed,{still have } ,and after an A-B comparison,has a definete increase in treble-so,not sure if its a peak or not..SN-2xxx
Both pair sound excellent..to MY ears,with the type of music I listen to-I prefer the one with the deeper bass,also,they give me a tighter fit=more comfortable.
Why would you believe they "fudged "the graph..?
If needed,I can take picture of the graph ,that came with the headphones dated 9/4/2012..I question this date..as I am the 3rd owner...?? ,so,maybe there is ,some fudging going on??
Anyway,I'm totally satisfied with my latest addition,and may??? sell the HE-6's,emo amp,& all the cables & adapters I currently have for them.
