BTW, I personally found the 1440 too hot for my tastes ultimately, but If one builds a synergistic system around them, they can sound quite good (esp for their price). I ended up keeping the 1840 instead, which I think are the best in their price range still. Yes, the bass is a little slow and lean, no they're not as hyper-detailed as the HD800s, no they don't have the body/slam of the LCD-2/3 or even the HE6, but they sound balanced, forgiving, open and don't commit any major offences. I find them to be a jack of all trades headphone, one that I'd pick over the T1 or HD650. Actually, speaking of the HD650, the 1840 feel like a natural upgrade from them (except in some areas of bass, for reasons mentioned earlier).
I kinda thought that same thing, except for the HD600 instead of HD650. I like the thicker presentation of the HD600, but also like the cleaner sound of the SRH1840.
