ART Headamp4 + HD-650 / DT-880 / AH-D2000 - Page 2

That's odd, your iPod is docked but there's still a volume slider on screen. When I plug in my line out adapter, the volume control disappears.

Yeah.  My volume slider disappeared when I had an old dock. 

This one is the "universal" dock as opposed to the "apple" dock. 

Whatever that means, that crazy Steve.

 

Official Apple product model A1153.

If you have an iPod Touch 2G, this dock and iOS4,

you will also have a volume slider.

 

My guess is that you either have the really old dock or the really new dock.

Funny how you say amps all sound the same, but then describe the Headamp as having a "neutral sound" rolleyes.gif

If you get more cans you'll need another head amp. and then to get 3 more cans to fill the jacks.

 

I was thinking, Im not home right now so i cant try it in mine, and i havent think of this while im home lol. could we connect 8 headphones at once? only con could be that you can only control volume for each 4 pairs.  does it work? mmm will try.

I don't know why you're trying to pick a fight with me.

I mean "neutral" as opposed to the amp coming out of a headphone jack on a receiver or the headphone jack on an ipod.  Yes, they sound "neutral" compared to all other external solid state amps.

You could use a Y-splitter or an A/B switch on two Headamps.  I'm not going beyond 4 headphones though.

So you pick and choose which amps sound different and which sound the same? The receiver has a headphone amp and the ipod has a headphone amp, but those sound different? I am not picking a fight, but your comments in this thread and your headphone comparison thread are ridiculous. You bring some great stuff to the forum, but then ruin it with a comment like that. If you don't want to believe in cables and other stuff, fine, a lot of others don't either, but I bet you can't find a handful of people on this forum who agree that all amps sound the exactly the same. Opinions are fine, but I don't think you have heard enough gear to make the claim that all amps sound the same. And volume is no indication of am amp properly driving headphones or speakers.

My last reply on this subject.

 

Yes, the iPod headphone jack and the lineout sound different.  I'm pretty sure 90% of the forum is with me on this one.  Oddly, I agree with most everyone on this subject.  My iPod 3G was severely bass deficient.  I just choose to bypass the headphone jacks and go straight for the lineout.  A "neutral" amp only amplifies the lineout signal as is.  No plus, no minus, no color. 

 

Compare your words "not picking a fight" with "your headphone comparison thread are ridiculous."  I'll just leave that there.

 

I hope that was a satisfactory explanation.  If not, feel free to disagree elsewhere.

If all amps sound the same is there anything other than a neutral amp? I am just using your words...

From left to right:

 

1. XB-700

2. AH-D2000

3. DT-880

4. HD-650

The Sony is clearly the easiest to drive.

It's hard to tell from the pic for the other three because they are so similar.

The Beyer is most difficult, even with this 32Ω version.  The 250Ω and 600Ω versions will be harder to drive than this. 

The Sennheiser comes next.

Last is the Denon being the least difficult of the three.   

 

I changed the starting point of the pots, so don't compare this picture to the review picture (before I painted the amp).

If anyone buys this amp and you also own "audiophile" grade amps, I would love to hear your thoughts on a comparison test.  Whether there's an audible difference or not, I'd love to hear your thoughts on this matter.  The only thing I ask is that you do the listening test double blind through the same Y splitter cable, and set the listening volume at the exact same level. 

 

As long as you are honest, please post your findings.  (edited)

If they're designed right they should.  The Art can introduce large frequency increases with certain headphones.  The K530 for example is low impedance and highly inductive, so with the Art's 56ohm output impedance you're looking at a 4.5dB increase at ~100Hz.  With the headphones he used I'm not surprised he couldn't tell a difference because the damping factor is high enough on the cans/amp combination or they're (the cans) are mostly resistive.

 

In this case the Art is probably more than sufficient as the headphones play well with it.  Just another example of why you should shop for an amp after you've picked headphones - it may save you money.

How does this do against the PA2v2 for $10 more?

Depends on the headphones.  This offers quite a bit of power for the cost, but certain headphones will experience frequency response error with it.  The PA2v2 is mostly a portable amp, so I wouldn't use it with severely inefficient headphones that also present a tougher load.

Alright good info, so on a DT 770 Pro?
