500+ Head-Fier
Just to point out another possibility. I had mine cut out and it was on the 3.5mm side. Was fine after replugging. So try that first
Having previously owned the HE-500 with Jerg pads, which were an improvement, I would still take the M1060 with my mods (Audeze pads and paper towel circle behind driver). With these mods you get the great bass extension and better sub bass compared to HE-500 with a little more mid bass emphasis, something most planars are missing. Mids when modded are very good as is the treble which is smoothed out considerably. I think they do a better job at sound stage, especially depth, where sometimes HE-500 was to left right for me. Another issue I had with the HE-500 was the 10kHz peak that would give air and sizzle but was unrealistic and could be fatiguing. These impressions are all with my modded pair. Stock for stock I would probably take HE-500.
Interesting. I'm guessing there will be driver variation much like Audeze models. I'll be able to measure my friends when he gets his after Monoprice has them in stock.
Yes, Vegan pads and 1 sheet paper towel, I used Bounty Select-A-Size Paper towels, 1 sheet cut out to 7.5mm or just over 3 inches.
