Wow things broke down for me for a couple days, was put in a position where I was possibly looking at losing all of my furniture and put all of my electronics away to protect them. Scary, is all I can say about that! Happy to report that in the end, my beloved HE-400 were not put up for sale and I am now enjoying the Stax SR-407 on demo from Justin at Headamp and unlike the LCD-2, I can definitely see myself going to Stax for my upgrade. I didn't want upgradeitis again but I willingly submitted myself to the disease when I signed up for the demo. I actually preferred the sound signature of the HE-400 to the LCD-2 (while recognizing that the LCD-2 are technically superior) but even this 407, which is like the bottom of the current lineup is just so refined with everything I throw at it.
Woa dude, HE400 is like the entry headphone for the higher end headphones it seems.
I have to say, I am intrigued by that stax headphone, is correct that it costs only 580 usd? What kind of amp does one need to drive it?
