Audio Bliss.. - I am no audiophile and I do like Bose qc2 sound quality (I had them for 4 years). I also own UE5 fi and Shure 500. I am the so call mass market but my preference starts to change a little after Denon D2000. I always thought my Shure E500 is already the best until I put these cans on. Very huge difference in sound quality. When I put on Peter Rauhofer (electronica) on, I really feel like I am live @ Roxy. The bass beat is as good as being in a disco and yet not overwhelming and no it does not sound like bass in the corner of the room. In jazz music I can hear the bass guitarist finger rolling on the string. All these becomes very obvious especially in Diana Krall live at montreal. I also tested it with Fillipa Giordano Lost boys calling (Ennio Morricone) and the bass came out simply remarkable. It can deliver very very low bass very clearly. I would say it does match the sound quality of a good system with a good sub-woofer place correctly (I had a Onkyo & Nad receiver, Denon cd-player and KHT2000 5.1 speaker) and the D2000 meets every expectation.The treble goes pretty high. All the ting ting ting sound especially in Jazz are very obvious. They are sharp, fast and precise. Also the more subtle sssszzzz when the drummer brush a duster on the drums (I dun know whats that call) is very prominent. And yes I feel like I am back to Laura Fygi concert live in SIngapore.The sound is expansive. Sorry shure but I paid $499.99 and bass and treble just cant cut it (so is bose qc2 & UE 5fi). I did try Dr dre bass beat and it sounded a little like a can.I did a test with a friend. I put bose qc2 on a friend first. He took out headphone after a min and said Yeah its good. I always like the way bose sound they are always good at bass, treble and they have been arond for along time .. blah blah.. ok now try D2000. His first 10 sec respond oooohh ooh .. wow oohh. There was silence until the end of the song.I actually wanted to get the D5000 but the cost and the subtle diff from other reviewer put me off (I dun know what is that little diff cause I have not heard the D5000). Instead I got the D2000 and a portable amp (THe RSA Hornet @ $399). The improvement is substantial. The signtaure of the sound is still the same but the Subtle Deep bass, Mid bass, extended high, and separation becomes more prominent. And when I off my amp, the sound quality becomes thinner. I know an IPOD or zune can power this to deafening vol but it just lack the punch without an amp. Dun get me wrong the D2000 still sound very very good without an amp. As the weeks went by I ended spending another $145. I realize the potential to improve the Denon is huge. My setup right now is Ipod 4th Gen (all lossless) with ALO Cryo SXC 22G cable ($145) lineout to RSA hornet portable amplifier. I did another blind test with my friend. This time with direct phone jack out to D2000 and other with Line out with amp & cable. He said The difference is like a walkman and a discman. My quest for that perfect headphone has ended. I highly recommend this headphone. Right now I am in Audio Bliss.Update: Forget the ALO cryo SXC 22G cable. Its not worth that money. Why? Cause I cant really tell the diff between a best buy $3.99 cable to a $145 cable. Most of the diff is made by the amp and not the cable. All my friends fail that cable blind test as well. Pls bear in mind the people that took the blind test are mass market ears not audiophile golden ears. Which means if they cant tell, u can be sure the diff is very subtle or non-existence?. But strangely enough when they are not doing a (blind test)test (I let them see the switch between both cable) they will tell me the ALO cryo SXC 22G cable sounded better. IMO The look of that cable is already a winner. I will say the cable diff is Psycho-imagination diff at the very best. cheers-)

Too much Bass, not recommended - Unless by some miracle, the bass starts getting attenuated with use, this is definitely not a good buy. I completely agree with all the reviewers who found the bass too much to digest...plus the Amazon.com dealer I bought this from, NetDeals, sent me an open box minus factory sticker so not sure if I am getting a hand-me-down...stay away from this product....

Very good--but.... - The construction is excellent. However, they are large, and as I am a smaller (5 foot 1 inch) person they tended to be uncomfortable, too large for the size of my head.The sound is heavy on the low end. While I could hear much detail, the lows were too prominent, overly rich. I like a bit more balance.

Balanced and Versatile - The D2000 are great headphones for just about any musical genre. Frequency response is well balanced with plowing, authoritative bass, clean, smooth midrange (I cannot understand comments to the effect that the D2000 have no mids!) and detailed, extended highs. The D2000 have both an adroit quickness and a liquid smoothness, making them quite special to listen to. While they do benefit extremely well from a good, dedicated headphone amplifier (I m currently using the Bada PH-12 and Darkvoice 337 to excellent effect), the Denon can sound ridiculously satisfying straight from a Walkman, the 1/8 jack from a mini-component system (JVC C-220C) or A/V receiver (Denon AVR-1905).The best, most versatile closed headphones I ve ever tried, and one of the best headphones, period, that I ve ever heard.

A do-it-all headphone - If you don t care to purchase a dedicated headphone amp and you just want to enjoy your music this is THE headphone for you. It sounds warm, lively, detailed, and beautiful. Plugged straight into my computer everything sounds amazing, even those 128kbps MP3 s encoded in 1998. However, these headphones might be a little bass heavy for some people. Your ears may vary.
