Denon AH-D2000, no bass problem (SOLVED)

post #1 of 48
Thread Starter 
My Denon AH-D2000 is the first hi-fi headphones I bought.
What I heard, AH-D2000 should deliver good bass, but I'm getting almost none (tried many kind of music). I did 30 hours burn in - difference was small. I can't believe that non bass problem only because of small burn in hours.

My source is: Sound card: Realtek HD Audio (what I know - it's better than Creative Live! 5.1) -> connecting my Creative Inspire T6060 to sound card -> connecting Denon to Creative Inspire T6060 special jack.
My T6060 (for $100) delivering a lot more amount of bass, comparing with AH-D2000.
(my W910 with megabass on showing no bass also)

(I also tried to change 5.1 to headphones settings in Windows and Realtek settings).

I have no experience in headphones, but I don't want to believe, that what I hear now, is what capable of AH-D2000.
My system is not enough to drive them? (I thought it would be easier to drive a 25ohm phones). The only way is to buy Amp?

Any suggestions?

If you have a audio CD player, tuner and a amplifier,
put the Denon in their headphone socket.
Do you have bass then?

You're really the first one to report the D2000 having a lack of bass

I don't have CD player...
Don't have any amplifier too, maybe this is the only problem...

Stupid question, but could they be fake O.o?

Its entirely possible. I heard a D2000 for the first time today out of my Pico and the bass gobsmacked me Truly impressive bass, especially to a basshead like me

Never heard of fake Denons. They are not that populair among common listeners (not Headfi-ers).
If you want to earn money on fake headphones, I suppose you choose populair models, like Sony's and the like. Not an obscure Denon headphone.

If you have a CD player in your computer with a headphone socket, try that one.
Of you have friends with audio gear, try the Denon on there equipment. Than you'll know if the headphone is broke or not.

Possible what? You meant about Amp?

"You are correct, Sir!"

Matching the set up to the phones is 80%+ of the challenge to achieving good sound with any headphones.

The D2000/D5000s need a good set up, with low impedance output (lots of current in contrast to lots of voltage) to sound their best - very much like Grados. Though, they do not require a "mega-buck" set up to sound their best - as the HD650s do.

The X-CANv8 is superb with the D2000/D5000s - though it's USB DAC may not be the best. But... it has the right impedance and plenty of power to drive the low impedance Denons really well.

You may be used to T6060s "artifical" bass. When I was using Creative I-Trigue 3220, I found the PX 100 bassless (though it was considered as one of the bass-heavy headphones). It turned out to be just a matter of usage. Now I consider my PX 100s as a bassy headphone

Oh, and do yourself a favor - connect your headphones directly to your soundcard. Headphone jack on the T6060 greatly degreades sound quality.

One way to combat the bass on the D2000 or the D5000 is to simply underpower them. I see you are not using a dedicated headphone amp. Give them sufficicent juice and the bass will show its true colors. Under-powering is not the best answer, though, as you will have loose bass, overall lacking dynamics and thrust, with a "slow" response sound, possibly clipping the amp, but at least, no more boomy bass.

When I listen to the D2000 out of my computer's sound card, the bass is like an indistinct, soft one-note foggy throb, but hey, at least it's no longer intruding into the rest of the FR.

You may be right about "artificial" bass... But still, I always using only 4 out of 10 bass levels in T6060, so I don't think that I'm bass spoiled

I know this, but somehow, T6060 giving me more power then audiocard (T6060 provides my 20% bass for my liking, but directly to audiocard about 5% of bass )

My wallet is empty after buying D2000
I can't buy X-CANv8, but I have resources left for a handmade "CMOY Headphone Amplifier - OPA2227". Will those be enough to powerup my headphones?
Sorry for the eBay links
Micro Cmoy headphone amp - Opamp2227 - Amplifier)

THey are low impedance cans, and should be easy to drive with anything. Are you sure yours are not defective in some way?

That's what I'm wandering also. They are known to have built flaws....

The problem is that I have nothing to compare with

The very likely problem is that you soundcard is not up to the job. The D2000 needs a reasonable amount of current and voltage before it springs into life. Most soundcards have a hadphone output that is based on the 5V power supply rail in a PC. Very few use the 12V rail to drive headphone amps sections. On top of that the audio output chip tends to be some little opamp that has less than 40mA drive capability.

So you'll need a headamp of sorts. You could try and hunt down a cheap 2nd hand general integrated amp with headphone output to start with since they can be had for far less than a decent headamp.
