What were the amp pairings (for the 560) like at the meet?
Soundsgoodtome: thanks for reporting on people's preferences for the pads, that's great info. (TMR: I know I'm totally on the Audeze end of the spectrum haha)
FWIW Justin_Time's review (pg 1 of thread) covers some of the effects he found when using different cables. He tried some silver cables and copper cables, and compared it to the stock cable.
The 6moons review says stock cable = silver + copper.
Thanks everyone for weighing in on the amp pairing comment, very helpful as I expect to be a happy secondhand HE-560 in time to come.
FWIW I'll be trying out the Vali and Pico (DAC/amp, not the Slim or the Power) first and report back.
