Suggestions? Under $400-ish

[eightbitpotion]

So I'm currently planning on a pair of livewires for my portable stuff, but I started thinking whether or not I want to invest in a new pair of home cans. I'm using the k701s right now, and am not willing to switch to the hd650 or the dt880/770/990...etc. I've not the slightest idea about AT or denons...and the similars. Is there a good phone in the sub 400 dollar range that I should look at?

-Needs very deep and accurate bass (punchy, not boomy)

-Soundstage is a MUST....a massive one. My 701s have spoiled me.

-They need to be extremely accurate and fast.

That's it! Any ideas anyone? Or should I just stick with the Livewires and 701?

Sounds like you're asking for a lot for under $400. The only phone I can think of that really meets your criterias is the GS-1000, but it is out of your price range.
