Would you mind sharing the serial numbers of your two pairs? Or something approximate or in a PM, as the "flatter 6k peak" that you mentioned really caught my eye and I want to make sure my second pair is more like your "#2 HD800s" in that respect.

Thanks for the kind words.  First, let me say I learned during my time in the music, TV and film business that specialist equipment is weird ... manufacturers spend about 30% of their time and effort designing it, and the other 70% trying to make sure it stays the same in production from month to month and year to year.  Consistency is critical - sometimes you move to another edit suite down the hall, and sometimes you move from a New York control room to LA, and you need to be able to trust that the gear isn't stabbing you in the back.  And manufacturers don't always succeed.

And Sennheiser isn't really a specialist manufacturer - it's a mass producer with a small in-house boutique operation for their flagships.  So I expected sample variation with the HD800 - and found it.  Not a whole lot, not night and day, not hugely dramatic - but certainly in tune with what we talk about here generally, and certainly much, much greater than cables, for instance.

Plus, overlaid on all that, is a rumor (not that Senn would ever admit it) that the HD800 is being revisited for more bass response.

So ... I now have 3 HD800s (yeah, I'm nuts) ... #6946 is my Leben pair, with the spike, but it's a little higher in frequency, closer to 7k than 6 (judged by ear: I don't have access to pro measuring gear anymore, and Radio Shack meters, etc, aren't good enough.)

#7883 is my Pinnacle pair, with a much lower, flatter 6k peak.

I think both of those are just random variations - it's a question of using Amazon or similar, trial and return.  I must have tried 20 pairs so far.

And the latest -  #9908 - definitely has stronger bass.  The treble peak is still there at about 6k, but modest, and it's much less apparent because of the bassier balance.  If the rumor is true about intentional changes, it looks like anything after about 9500 is "new."

Yes ... possibly!  There was a thread on here with postings of the curves that Senn supplies to registered owners, and even though they weren't very detailed they showed variations.  It's to be expected given the nature of the operation.  Whether or not there's a conscious decision to bump the bass is unconfirmed.  I'm only passing on whispers I heard.

Yeah, really.  LOL.  My wife is bemused - but she has her equivalents.  I have a great job and happily I can indulge myself, but still, it took ages to break through an internal inhibition that I guess comes from years ago when I was struggling.  It was a big psychological barrier.  But I worked on it and broke through!

All CD, no computers.  Sources are Meridian G08.2 for the Leben; I recently moved the Esoteric DV-50 to the Pinnacle; and Bryston BCD-1 in the rotating third spot (which until recently was HE-6 out of a Bryston B60 and is now the new HD800s out of a Luxman P1-u.)  I run balanced lines where possible (no cogent reason, just old habit) and use Audioquest King Cobra cables (again, no cogent reason except they're well made, and from a durability point of view I like welded terminations better than soldered or crimped.)  Power cables are all as short as possible, either 12", 18" or 24", from Newark.com - the 24" were the costliest, at $3.47 - except for a couple of 36" Nordosts which I already had from youthful foolishness.  All are plugged into a PS Audio Juice Bar II (no audio reason, but it's well made.)
