Hi Xenophon...your observations inspired me..
I have finally let go of my HD-800s after along love-hate relationship using them with a V200-V800 stack [in balanced mode]. I found them a little fatiguing and not always very involving....and at times the treble just plain irritating.
I have now ordered some HE-500s.
Any advice on gain\DC offset\ gnd or lift settings for the Violectric stack with the HE-500?
Any recabling necessary or advisable on the HE-500s?
Thanks in advance
