Romy where'd you hear the Orpheus?


There's a fellow in Houston with a set, an acquaintance of one of my audiophile buddies. We had a mini-meet at his town home on two separate occasions. That was also the first time I heard the R10, incidentally.

I mostly talk about music there. Weird.

Just drooled on my keyboard.
LOL! Did the same thing  :P. If these sound as good as they measure, I gotta hear them! Except there are no meets in France  :(.
Are they really neutral or do they still have some kind of coloration?
How's the bass compared to HD800?

Jesus.








Would be nice to hear some subjective impressions as well - never gonna own these, so might as well live vicariously through someone else.

wouldn't mind a dynamic with that kind of response either... obviously Senn is lying when they claim the HD800 to be neutral.


It's obvious the HD800 is diffuse field, HE90 isn't so I'm not sure what claim of neutrality Senn is making w/ the HD800 unless one assumes diffuse field is neutral.  A claim I've had a little trouble w/ going back to the ER4.

I think they might have for the HD700.   ::)  I know plenty of users who don't work for Senn making those claims though.

HE90 is one/two minor points of EQ and some deeper bass impact away from being perfect for me.  Closest yet, when it's on it's on.  Not all HE90 rigs have sounded the same to me so far though which I believe is due to amp variances?

Headphone variances as well. The ones sold in the Jan Meier group buy have more upper midrange energy than the vintage ones sold with HEV90 amp.

I have always loved the HE90 but not out of it's native amp. Always sounded much too romantic for me. I, like Anax, have always found them to sound different and I always imagined it was due to the amp and/or rig it was attached to. Very impressive measurements.

WTF couldn't Sennheiser release an Orpheus II instead of the craptastic HD700?!?!?!?

Because Beyer has nothing to compete w/ the HD800, why bother?  I think the recent proliferation of $2K+ phones has Senn dusting off the schematics though.

I was told some things that have me believe they at least were working on something big.

Hopefully their headphone amp sells well, as I'd imagine they'll use that as a guiding point for determining their market opportunity for more high-end products.

In my experience this extends much further as there are huge differences even in the original production run.  Compare the first sets, middle production and the last few dozen and they are all different. 

How the stators were made was in its infancy in 1990 and there was no consistency so they tried to match and tweak.  The amp also went through two major design changes but I never got a straight answer whether they tinkered with the headphones to match these changes or not.  The engineers didn't even want to admit the differences in the amps until I showed them my proof...
