Retirement is coming up so time to divest myself of some excess stuff.
One thing I have is a lot of headphones (too many) so time to see how these things stack up.
For the conventional headphones, amplification is my trusty old Woo Audio WA6.
It's not the best thing out there but I have an attachment to it.

I always use Zappa's Apostrophe' for testing sessions as it's so well recorded and there's an awful lot of stuff going on with it.
Up first were some Beyerdnamic Amiron Home headphones.

Bass was kind of heavy, the overall sound was a bit muffled and distant.
Comfortable enough, though.
NEXT!
Up next was a pair of 600 Ohm Beyerdynamic DT990s.

Sound was better than the Amirons, a bit bass heavy, decent midrange and treble but not quite there as the whole presentation was a bit distant.
These are very comfortable headphones, the ear pads are great.
Maybe that's as good as regular headphones get?
Let's try some Sennheiser HD650s.

Much more betterer.
Not as comfortable as the Beyerdynamics but the sound is much more immediate with great midrange and upper end clarity.
Top end appears to be a bit "hot", bass seemed to be appropriate to the recording.
I think the sound would be more fatiguing over time than the DT990s, though.
Let's see how they stack up to my old Stax Lamba Pro with the Stax STM-006tII amp (tII as in two tubes).


These are the top dog.
Comfort is decent, they don't weigh much, soundstage is just right and top to bottom the sound is spot on.
The downside to these is they're fairly fragile compared to the other ones listed.
If I didn't like that Woo amp so much, I'd sell off the others and stick with the Stax Lamba.
As it is, I'll keep the Stax and Sennheiser.
