I think the SR-009 is the best headphone I've ever heard. It's about the only headphone that has good treble response, but no apparent area of exageration. Smoove as a baby's butt. The lowest notes aren't quite up to Audez'e extention and punch, but boy these do very very well for an estat.
Currently have this gear on my kitchen table:
HeadAmp Blue Hawaii ($1248.75); Apex Audio Pinnacle ($10,000); Wadia 861SE CD Player ($9,950); Stax Sr-009 ($5200); Stax SR-007, Mk1 late version ($2600 for current MK2); Sennheiser HD 800 ($1499); Audez'e LCD-2 late Rev 1 ($995); HiFiMAN HE-6 ($1199); HiFiMAN HE-500 ($899).
That's $32,000+!!!

Miles to go before I sleep.
