Question about Denon ADH7000. - Page 2

post #16 of 20

The D7000 has very low impedance, which always misleading people it should be good enough driven by any portable device. From the experience on many low impedance headphones, this means require much more power current from the circuit of amplifier. If the design of the circuit doesn't have this be considered, the sound will getting worse. Therefore, in simply say, such low impedance headphones are easily to be driven, but difficult to have best sounding. If you have the D7000, you can notice a huge difference between direct driven by a portable device and a desktop amplifier.

This matches my experience with the D2000 -- you could get it loud enough from a portable device, and it sounded acceptably good, but the sound definitely improves a lot with good amplification -- in particular, the bass tightens up considerably (which makes sense, since the bass requires more sustained current than the mids or treble).

I think I'm echoing the common wisdom here - the D7000's sound surprisingly fine out of my iphone.  They sound brilliant out of my Headroom ultra desktop.  They scale phenomenally well with amplification, but sound surprisingly good without an amp.  Note they are big, beautiful wood headphones.  Not really a portable choice in my opinion.

The difference between direct driven and desktop amplified, is very depending to the SQ of the desktop amplifier. Think about how a $500 level amplifier different with the $2000 level counterpart in overall sounding. A headphone with better SQ, the higher grade of amplifier is required to show its edge. D7000 is not an exception.smily_headphones1.gif

 

You will noticed the sound of D7000 is so different under different amplifier, and the level of burn-in. At beginning, the D7000 sounds not so big different with the D5000 when it was out of the box. But after 1000 hours, D7000 can kick the axx of the D5000 in every aspect under a $1000 or above level amplifier.

wow, what a price.  Anyone know when this coupon will go dead?  I'd like to see if JR will price-match since I'm more comfortable with them and their return policy.

 

edit: never mind.  I ordered anyway.  I doubt JR will match that and I double-doubt I'll feel compelled to send them back for lack of satisfaction.
