This issue you guys are up against has me bothered. When I re-read what had been said,
"I wanted to achieve 'eargasm' level, amp that give me the best "WOW" factor... currently my source is great enough to feed any single ended amps, and the built in amp is superior than any of solid state amps that I owned before. Doesn't mean I want to stop here, I just wanted to get a tubes amp, and wanted to experience it's lushness, rich midrange, and more 'emotional' in my own word."
and thought about this for a while, the question that came to my mind was, Has anyone with K701s acheived the same "special synergy" with a tube amp that HD-650 owners have been acheiving since the LDII++ came out? I honestly don't know. If it has been tried and can't be duplicated, wouldn't it be easier and more cost effective to buy the HD-650 and any one of the amps with this "special synergy" and start enjoying? Just thinking out loud.
