Getting the Most out of my D7000's, a Computer, and my Iphone 3GS - Page 2

What do you want from it. I mean, how much SQ do you want from it's potential. These are rough rough estimates from my experience. 

 

Straight from an iphone I rekon the best is around 60%

 

Say a ipod/sansa with rockbox (3rd party firmware) and a line out to a small portable amplifier: 60-65%

 

Say directly from a samsung galaxy s (with rooted 3rd party kernel: voodoo sound), or a large cowon personal media player, 70-75%

 

 

 

For me, if I were to spend on any headphone, including the denon d7k (i've bought the d1001, d2k, d5k- just by principle don't want to get the d7k. It'll make me feel too denonish), I'd wan't to feed off at least 80%+ of its potential. And for that, i'm afraid you really need a desktop amp/dac configuration.

 

A fiio e9 as an amplifier, and a fiio e10 as a dac (connect both together with a 3.5mm to 3.5mm cable) would set you back less than £120. And I reckon this would reveal around 85%+ of the denon's potential. 

 

 

Again, don't take these figures as anything accurate. Illustrates a point though.

 

The D7000s require a low output impedance. And that's about it. If it wasn't for the bling factor, I'd use them as portables for my Clip.

Disagree? DBT it

Your only option is a Schiit Lyr

I have heard the denon d5k, denon d2k from the sansa fuze.

They sound horrible.

Very very bad.

Then I'm glad I don't share the same schema as you do, otherwise I would never be able to enjoy a piece of audio gear unless it's overpriced, overpowered or otherwise tweaked.

BTW, have you tried testing the Fuze under a volume-matched DBT protocol?

I've listened to the D7K through an assortment of portables. As their specs indicate they're an easy to drive headphone, your hyperbole to the contrary notwithstanding. I don't mean to offend, but this is about the only forum on head-fi where flaky percentages and subjective bias don't amount to anything.

Then again, this thread was posted in the wrong forum.

If he'd just posted on the normal forum, I'm sure somebody would have recommended him an expensive LOD cable and some fully-discrete monstrosity by now.

the denon's d2k and d5k are very easy to spot when the source doesn't quite cut the mustard. 2 things happen:

1) a degree of a collapse of the soundstage.

2) placement of the mids in relation to this soundstage

3) sub bass strength

This all happens when driven with the sansa fuze, rockboxed to the d5k. No equalisers or anything else on. I've done many tests, often with different pricepoint dacs, and i've many times been bewildered with the similarity of different dac's/amps.

But with the denon out of the sansa, there's no need for any of this.

What's on my tiny desk now: fiio e9/e10. comparing the denon out of the sansa fuze v2 and the fiio (volume matched), and the difference is very very apparent. It really is a no brainer. Hearing the denon from my denon cdp reveals further improvements. No surprise.

I'm not one to say spend as much on your sources as your headphone. So you don't need a £700 dac/amp for the denon d7k. My view is to have at least a basic 'good' source for high end full size 400g headphones. Something that's passed the test and unanimously considered a good enough source from the folk here at headfi. And for the lowest price, I can only think of the fiio e9/e7. The e9/e10 improves on this and it costs less than £130.

How does an amp affect any of the three things you listed, if you already have enough voltage for all the peaks?

I'd recommend you get someone to help you with an ABX test.

Again, i'm not hot on the need a huge system and a £500+ investment to enjoy the denon d7k.

Just use it from a samsung galaxy s i9000 with voodoo sound installed. No amp. No lineout. Measurements put this in the same bracket of desktop amps/dac's like audio gd nfb12.

Having both the phone and the nfb12, I can confirm from a short test that with the denon d2/5k, they are similar.

The fuze is just a joke though. Seriously.
