These £800 monsters were, for us, the most exciting headphones of the year, and after over a month of testing and daily listening, we're ready to sing their praises. They're on sale now.
The D7000s give an even higher level of luxury than their D5000 brothers -- if that's possible -- with glossy varnished mahogany enclosures, golden lettering than doesn't wear off over time, and larger, softer leather earcups. They're also a little more snug than the last version, clinging to the head better.
Although unchanged internally, cabling has been improved. The D7000's Elastomer cable is less prone to tangling and more resistant to being repeatedly packed away and unpacked. Good news, because our in-house D5000 cabling is looking battered these days.
Of course one of the main selling points of the D5000s was the use of real wood to house the drivers. This appears largely unchanged here -- they exhibit the same natural warmth that the wood provided in the previous model.
What hasn't changed much to look at is the padded leather headband, which still extends delicately on ball bearings. We found them extremely comfortable, with looser clasp to the skull than the HD 650s, but more so than the D5000s. They're one of the most comfortable pairs of headphones we've ever used for hours of perpetual listening, beating the Audio Technica, Sennheiser and Beyerdynamic models we've become so fond of over the years.
Inside these lightweight enclosures are microfibre diaphragms, and behind them a 50mm Neodymium magnet. Denon claims the D7000s feature more powerful circuitry than before, enhancing the magnetic power of the drive unit by just over 10 per cent.
Many other specifications remain largely unchanged. The cans can handle a 1,800mW maximum input, respond to frequencies between 5Hz-45kHz, feature 3m of 7N-OFC cabling, and offer a very low impedance of 25ohms. But they have a slightly increased sensitivity of 108dB/mW, however, compared to the D5000's 106dB/mW, helping to yield a marginally louder output.
What's interesting about these headphones is their impedance, or the amount of power required by an amplifier to drive them. Such a low impedance means they're more easily handled by portable players such as iPods, whereas more power-hungry cans really should be used with a headphone amplifier of some kind.
As such, we've tested these headphones with our usual reference amplifier (coincidentally also a Denon), and a hand-built Woo Audio 2 valve-based headphone amp -- which, actually, is typically more suitable for higher impedance headphones. Our musical choices came from both CD and Apple Lossless-encoded files from an iPod classic, via an Arcam rDock.
The first thing we noticed was the tighter, slightly less boomy bass. These cans have a hugely extended low-end response, and to accompany it is an even more transparent, open and detailed treble. A hi-hat rudiment during Ingrid Michaelson's Starting Now was just that bit clearer through the D7000s -- just that little bit more detailed and more believable.
