The D5000 sounds very good to me, just as they are -- I would not let anyone mod them, even if for free.

Hopefully all of you who are curious will have a chance to compare the stock version with the mods. The posts I've read and the people I've discussed the matter with have come to similar conclusions. I know that someone wrote a great comparison a few weeks ago. I'm sure a query would find it. It was clear to me that this person had different sound signature preferences from myself. But his/her objective assessment was consistent to mine. If I recall, she/he enjoyed the more veiled highs of the stock, where as I don't. |
It's just basic physics. You have an enclosure which is not damped, a resonant material, which is wood, and if you detect that some frequencies get bloated, resonant and obscuring the rest of the spectrum, you just try to damp and fix those resonances, which is what the mod does. |

If not then I can see how using this "fix" would be acceptable. In my case the Singlepower MPX3 amplifier I use has no issue with flat frequency response in the low frequency range. The music I listen to is Jazz, Blues and classic rock. So, what we have here is a mystery that our "opinions" simply will not solve on this fine day |
also take into account that the D5000 are very low impedance cans (24 Ohm IIRC) and not specially sensitive, so the combination of a highish ouput impedance from a tube amp, with the low impedance at the cans, can roll-off the bass quite a lot, probably more than 3dB compared to people using low output impedance SS amplifiers. |

Big companies produce items to meet some requirements into a price point to reach a market segment. They probably could have done better, but it had been more expensive, so the final price had been higher and the potential market, different. Sony went really mad to make the R10's enclosure as it is to offer a product with no sound compromises. So it sold for 4000 USD. The JVC DX-1000 don't have those resonance issues, but the wooden enclosure is more elaborated, has a double inner chamber and also the price is higher. I don't think there's anything to criticize in people prefering the cans with those problems improved. You like the cans as they are, OK enjoy them, I won't be censuring you for that. Rgrds |

If you're into audio, you'll also know that fine engineers making interesting audio products, not only rely on measurements, but also in music and listening to it through the devices they're designing. Maybe the people at Denon skipped this step hehehehe. IMHO it's quite naive believing that everything made by an engineer should be perfect and faultless. There are lots of crappy products out there. Regarding the measurements, I'm waiting for my sound engineer friend who owns the testing gear and is away, to come back in order of having the MD5000 measured. Maybe in a couple of weeks or so. I'm not sure we can measure the stock ones since I don't have them, but I have these measured too with other lower quality testing gear. This could provide some reference point, but not as good as I'd like. Rgrds |
I don't think Denon would cut corners for their flagship headphones. If anything, they really did the best they could without bumping the price above 1K. Still, I doubt they could have made much better. |

To make a headphone cheaper than the D5000 to build to a price point. I feel they did the same with the D5000. Can we at least agree that almost every other headphone past and present you can name with a sticker price at or near the D5000 has superior build quality? I love these cans, but man, that frame and the build is really flimsy. Mod-ing it firms it up, controlling all the resonances. Good speakers are (in part) distinguished by being full of internal bracing and damping. They tend to weigh a lot more than the Best Buy specials. You'll always see reviewers rapping on the outside of the speakers testing how much they vibrate. |
