As the titles says anyone who has heard all three?
I'm also interested in low volume listening performance..
Which of these maintains the same character at all volumes?
two of the answers were the same ;)
I'm shocked you think the K1k sounds similar at all volumes - i found it rubbish at low levels! They are so far beyond the standard definition of "open," that not only is rolloff a huge problem at low volumes, but the sheer amount of outside noise makes the experience entirely different once they are no longer loud enough to block out external sounds
It has been awhile since I last heard the K1000, so I could see that they can be better as well. Honestly though, they are all great phones...and I can't wait to hear my OII with either the BHSE and T2 in the future.
Correct you are! The are all great cans.
Back for a moment after more than two years... I should be ashamed... I need to know more about this new Stax...
Anyway, to stay on topic, this is a very easy one:
Qualia >> O2 > K1000 (owning all of them)
Nothing like the Qualias for keeping the same sonics even a incredibly low volumes.
Electrostatics are not that great because their amps driving them at low volume usually don't perform great, especially with O2s.
But the K1000 is especially bad in this regard for a dynamic can so even the O2s beat them.
A trick for most electrostats is using a source with variable output. As I said the problem is usually in the amp and not in the can so an attenuated source with medium amplification will make electrostats sing at low volumes (quality can take a bit of a dent though).
Still... you are better off with the Qualias.
PS: You can use that trick with several dynamic cans too but works better with electrostatic ones.
