    Beyerdynamic DT 990 600 ohm or 250 ohm?

    thanks for your post Velourears   I have a Asus Xonar Essence One computer amp for driving these so I'm thinking of getting the 600 Ohm versions and your review was great help.  What do you think of the new Tesla models? T90   being only 250 ohms....?

    So to answer my own question... there will be no other impedance version of the T90. i just got off the phone with Beyerdynamic.  Also they  said there is no plan to make a T80 version.

    Beyerdynamic T90 Discussion and Support Thread

    Hello.  I'm looking for a set of headphones for my Asus Xonar Essence One but was thinking of getting a 600Ohm pair simply because this amp was capable of pushing that much.  Do we know if Beyerdynamic is going to release a 600Ohm version of these?   Thanks

    Quote:  Tim & Whit3Rav3n,   Thanks for going about re-tesing 6moons results.  This is way beyond my abilities.  I just wanted to figure out if I could drive the HE-400 / HE-500 properly using the E1.    Tim, I see that you own both of these... How do they sound on the E1?  Do you...

    Quote:   Hi Tim,   According to Asus webpage http://www.asus.com/Sound_Cards_and_DigitaltoAnalog_Converters/Xonar_Essence_One/#specifications   They say "Headphone : 7 Vrms ( Vp-p)"   and so @ 32 ohms   that would be   P = V^2/R      ( P = 7^2/32 )  ( P = ~1.53 Watts)    ...

    Quote:   Tim,   I am curious where you got your specs of the E1. Specifically you claim that it can do 600mW @ 32ohms. I'm looking online and in the user manual and can't find any details on the power output abilities.

    Comparison between Hifiman HE-400 & Beyerdynamic DT-990 250Ω (w/ pics)

    Any chance you've tested these headphones with a source other than " Spotify Premium (320 kbps)."   Thanks for this great comparison though!    Cheers
