Hello again! My pair of HTF 600's are still dying. But, I followed the recommendations in this thread and picked up a pair of Denon AH-D2000 and did a side by side comparison.
First, depending on where you buy these Denon's are around $250. I did not find the deals noted in this thread and so spent closer to $300. This is compared to the $60 (including replacement pads) I spent on the HTF.
My initial impression on the D2000, wow. These are my first pair of > $100 headphones ever. Everything about them feels well built. Not a single piece on this feels cheap.
When comparing the two cans together, I just have to say that the HTF impressed me even more. When I first got them, I was very happy with the sound as compared to the normal gamer headphones. Now that I am comparing them against a higher priced can, all I can say is they are an incredible buy at $30-$60. Hopefully the failure on my can was just a small % manufacturing defect.
For some details.... I can't really give much as I am not an audiophile. The D2000 feel like they have an extended bass range; as in I can hear/feel a lower bass frequency as compared to the HTFs. So on songs where the bass is not a beat, but a rumble that trails off, you can hear the trail go further on the D2000.
The bass on both models are about equal on punchyness though. So on songs where the bass is a beat, it is difficult to tell the difference between the two cans.
For the mids, the HTF seemed, more alive. I would say more in your face. The D2000 had a fuller mid section. As in, the HTF was exciting but the D2000 showed you detail you missed in that excitment. The D2000 seemed to handle the female voice better though, more dreamlike than the HTF.
For the highs, not too much to distinguish them here. The music I listen to is digital in nature so I'm assuming very high frequencies are not there. I had to EQ the HTF up a bit on the highs to get the details. On the D2000 I had to dial this back down.
For my games (mmo and FPS, not competitive), the D2000 handled the explosions and music/ambiance better simply because no single effect could overwhelm the others. An example would be an explosion that felt just as deep, impactful as the HTF but you could notice a bird singing or a cricket chirp in the middle of the madness.
Soundstage or seperation between right and left seemed very similar on the two models.
Sorry for the lack of techical detail!
In the end, if I had a friend looking for a new headphone I would recommend they pick up the HTF. For the price, the sound quality, they won't be disapointed. If they love the HTF and the type of sound it gives them; and they were willing to spend more, I would say pick up the D2000. It gives the same type of sound signature, just better. Enough to justify the price difference? If you can afford the D2000 then you can afford to pick up both. If you can't afford both, then the sound difference is not enough to justify the price.
I'll be checking out of this thread as I need to find a new home to discuss my new cans. Also as a last note, no burn in on the D2000 for this comparision.
Thank you for the great run and suggestions!
