The SR-407 is normally paired with the SRM-006tS for $2000 (the SRS-4170 combo), which puts it up against some serious competition. The headphone is $580 by itself, but the SRM-006tS is one expensive amp. That combo would have to be as good as the average flagship/matching amp stack to justify that price.
Justin, I know you've mentioned that the SRM-323S can power even the Omegas, but what's your take on the additional amount of performance that can be extracted from a Lambda series Stax by upgrading to the more expensive amps?
I know we all want the SR-009 and BHSE, but that's a little pricey.
