That sounds a lot like how people who don't like the DT880 at all describe its sound. Of course you're in the appreciation thread, so you'll get a lot of responses from people swearing it must be the amp, but I've read the thin-and-clear description even from people using well-known and respected gear. The DT880 isn't for everyone, and if it's not your preferred sound, that's perfectly all right. This hobby is all about finding the right sound, and there are lots of different preferences and lots of different headphones to suit them.
If you get a chance at a later date and with a different amp, certainly do give the DT880 another listen. Then you'll know for sure if it's the Beyer amp or the headphone itself you don't like.
I would say this is close to the mark. But I also said in an earlier post that I changed my ear pads to a much more solid and less leaky lambskin pad. This didn't suddenly give them an entirely different sound signature, but it did make them a lot fuller sounding compared to using the velor pads, and the bass was more present. They sound the same when switching between the pads on either the Essence STX or my Lyr. Both of which are plenty strong enough to power the 600 ohm version.
I'd prefer something beefier that plugs into a wall to power my DT880. I think that is why you are hearing "thin" or maybe it is still not burned in because I thought they sounded bad out of the box. They definitely don't lack body but at the same time they don't have the midrange body of the more expensive planars, or the subterranean bass of the LCD-2F/Alpha Dog, or the... well I will admit they have nice treble although with a little bit of sparkle/emphasis. Still though they are a jack of all trades and a close-to-neutral can for under $300.
I still do not believe this is anyting other than placebo. Especially after being told by countless posters on the Ultrasone 900s thread that they required "400 hours" of burn in before they start to shine. Yeah right, even after 500, they produced the same awful sound as when I first listened to them. If there's any kind of "burn in" happening, it's you getting used to the sound. My ADs do not sound any different after a 1000 hours than when I first listened to them.
If someone really does not like the sound they are getting out of the box on a setup that can power them decently, it would probably be wise to get a refund before thirty days (or however long the return policy is) instead of wasting time using pink/white noise or whatever voodoo that's supposed to work to change them. Even if there are measurable differences, they are so slight that it won't make you suddenly like them.
I completely agree with your last statement though, although I haven't actually had dozens of headphones to listen to among the same price range. I don't feel like I wasted my money with them, and I purchased them when they were around $100 more...on top of another $80 for the pads.
