Audio Science - Matching Headphones, Amps, DACs, Etc

post #1 of 15

Hi folks.

I've been doing some reading, looking through threads, guides, stickys, "how to's" and I haven't found a real solid explanation of how a person goes about selecting not to mention even determining what equipment they need to go with their headphones they would like to purchase.

For example, when picking our computer hardware you have to look at things such as chipset, voltages, timings, etc.

So my question is, how are people making recommendations of certain products to people?

I often see things like "those headphones require an amp but these don't".. How does one make that determination?

Surely people arent just blindly making recommendations purely on word of mouth, so what technical details determine whether headphones require an amp, dac, or soundcard? How do the number of Ohms affect the headphone?

Anyone got these answers?

If you want to provide an example using a specific product, use the DT770s since they are something I may consider purchasing in the future.

Volume in headphones comes from an amp, either on a soundcard, built into a DAC, or standalone. An amp just needs to push enough current to the headphones to get them to sufficient volume without distortion. That depends on how loud you like to listen and the sensitivity of the drivers.

DACs and amps can be either transparent, with no distortion, or "musical", with slight distortion on frequencies the manufacturer believes people will enjoy. Tube amps in particular are an old technology, but people still use them because they look cool and tend to have a smooth warm sound (distortion). When you are looking at your audio chain you have to think about what end result you want. Someone using high end neutral headphones (some people will call this sterile), like the HD600, might want a tube amp for a warmer sound. If you got the DT770, which is already a warm headphone with lots of bass, a tube amp might be too much and muddy up the overall sound.

On the technical side, you want the input impedance of the headphones to be at least 8-10x the output impedance of the amp to avoid distortion. For example, the Asus Xonar STX headphone output has an impedance of 10.7 ohms. This would toe the line with the 80 ohm DT770, but still be OK. If you wanted to use the 32 ohm version, you would want a dedicated amp to match impedance. Amps like the ODAC or Schiit magni have an output impedance under 1 ohm, and can be used for even very low impedance headphones and earphones. The 600 ohm headphones usually need more current, and require a standalone amp to power them.

Thank you so much. This is the information I was looking for, but I do have some follow up questions.

1.) When looking at a soundcard for example, how do you know its impedence is 10.7 ohms?

2.) If a person is running their iPod earbuds off their motherboards integrated sound card, how does this work? Do the same 8-10x rules apply? For example, these random ear buds have an input impedence of 16 ohms, does that imply that the integrated sound card has somewhere around 1-2 Ohms of impedence (16 / 8 = 2 or 16 / 10 = 1.6)? Whats the normal impedence of an integrated sound card on a motherboard or on a phone?

You lost me here. I'm guessing a amp or dac with 1-4 ohms of impedence would work for a 32 ohm version?

Power them. What do you mean by that? I'm guessing you aren't referring to Ohms anymore.

1) Unless you are looking at a hi-fi item, the manufacturer might not tell you. There are a lot of audiophile blogs/forums that have people with equipment to test that kind of thing.

2) Notice I said AT LEAST 8-10x. Check out Ohm's law. With headphones, as the input impedance goes up it takes more voltage but less current to drive them. If you take a pair of headphones with inefficient drivers, it can take a powerful amp with plenty of voltage to drive them to sufficient volumes. With low impedance headphones, if the output impedance of the amp is great than the 1/8 magic number, you'll get distortion.

I have no idea what the output impedance on motherboards is, and I couldn't find anything on it. Probably because anyone who cares has dedicated audio equipment anyways.

The O2 amp, for example, has an output impedance of 0.54 ohms. This would work with even the 16 ohm earphones without distortion.

My Titanium HD has been reported as having ~35 Ohm output impedance on the headphone port, which was fine when I was using 250 Ohm headphones. Now that I'm using 32 Ohm earphones as my main set, 35/32 is a horrible ratio and muddying everything up. I'm planning on building an O2 amp pretty soon.

Okay I'm more than familiar with Ohms law, so in that context your explanation makes sense.

So to clarify, the O2 amp with an impedence of 0.54 Ohms basically is suited to power anything with an inpedence greater than (.54 x 8 ) without producing distortion?

While we are on the topic, whats the difference for example between the DT770 32 Ohm, 80 Ohm, and 250 Ohm? Is the difference more so surrounding the equipment necessary to power them or is there a sound quality difference associated with this?

Does it make sense to have an amp without a dedicated sound card or does it make more sense to go for a dedicated sound card?

There are some reviews comparing the different versions, but I would suspect these are simply bias or done with improper equipment.

Take a look at this http://www.head-fi.org/t/513393/guide-sonic-differences-between-dt770-dt990-models-more

Now see how this guy describes the 32 ohm moving up through the 600 ohm DT770. As he gets to the 250 ohm he talks about how the bass opens up blah blah. I would suggest that the amp he is using (which isn't stated, but he mentions a great deal of tube amps near the bottom) has an output impedance that is distorting or under-powering the lower impedance models, but works fine with the higher models. He could also have a bias towards the high ohm models because those are historically associated with Hi-Fi. Old tube amps often had higher output impedance, so they made headphones with higher impedance as well.

I would suspect that with a near 0 impedance amp with sufficient current/voltage, they would all sound about the same.

You need a good DAC to get the best sound, which can come from a standalone or soundcard. If you care about gaming, a soundcard is one of the few things that will provide simu-3D sound imaging.

DACs: ODAC, Schiit, Headroom, iBasso, many others
Soundcards: Titanium HD, Z series, Xonar series
Amps: O2, Schiit Magni. These are the only two I have experience with and have very low output impedance.

Garbage in, garbage out. If you try to use new headphones and amp with your onboard, it's still going to sound bad.

Here is headroom's freq graph comparing the DT770. I think the unlabeled one is the 250 ohm. You can see that the 32 and 250 ohm are almost identical. I'm not sure why the 600 drops off on the very low end.



Here is an explanation by ClieOS from Head-Fi, better than mine
Quote:
To my own understanding, output impedance affects in two ways:

First, dampening. Transducer is a mechanical device, so it has inertia. When you push the diaphragm out with a signal, ideally you want it to go back to its original position immediately after the signal ends before the next signal comes. But in the real world, it will vibrate just a tiny bit before it fully stops. The vibration becomes the noise since it isn't there in the electric signal. There is already mechanical dampening in most transducer design (i.e. the rubber ring that connects the diaphragm to the metal housing), but electronic dampening is better. As the vibration itself creates a tiny bit of voltage and will get fed back to the amp section, the amp section will then compensate / resist the voltage change which forces the vibration to stop quicker. However, this kind of dampening usually works best if there is a big enough difference between the output impedance and the load impedance. 8x is the minimum but some will say 10x.

Second is impedance interaction. The impedance of a headphone changes with frequency. Most of what you read in spec is measured in 1kHz tone. A 32ohm @ 1kHz headphone can have a 16ohm or 64ohm impedance @ 500Hz, or 150ohm @ 15kHz. This is referred as a impedance curve. Sometime you can also have headphone with very linear / flat impedance curve and maintain 32ohm from sub-bass to treble (though it most case, impedance is usually higher at upper treble). The problem is when headphone has a curvy impedance curve - for an example, if a headphone is 4ohm @ 100Hz, 16ohm @ 1kHz and 120ohm @10kHz. When you drive it with an 10ohm output impedance, the headphone will see much less power at 100Hz (as the 10ohm output impedance is big in ratio compare to the 4ohm impedance of the headphone so most of the power will be waste), a little better at 1kHz but fine in 10kHz. This effect will change the final frequency curve of the headphone, thus adding coloration. This is particularly true for multi-way IEM since they tends to have very curvy impedance curve due to the use of crossover circuit. Again, a 8X difference is suggested in order to make sure the output impedance of the amp is far enough away for the impedance curve of the headphone so interaction will be minimum. In the case of IEM, less than 1 ohm is usually preferred since it will make sure the ratio is almost always greater than 8x.

Though might not always being the case, many dynamic driver have more linear impedance curve so dampening is more important. You can have a 32ohm dynamic headphone sounding very linearly / no coloration with amp of 10ohm output impedance, but you might not get as tight a bass since dampening is minimum at best. On the other hand, since balanced armatured tends to be very well mechanically dampened, impedance interaction is more important factor to consider when dealing with multi-way BA.

Okay, makes sense. This is what I was assuming was the case (for the most part -- some bias).

Yeah, garbage in, garbage out : ]

Does a DAC used in conjunction with onboard make sense? Ie: Does the DAC do a sufficient job altering the signal to maintain a high quality signal when converting from digital to analog?
Or is it best to go for the soundcard so that the higher quality signal is produced/altered right at the source?

Is one better than the other?

Your onboard IS a DAC, so is a soundcard. Digital is all the same until it's changed into analogue, but you can still apply DSP effects like dolby headphone or creative's CMSS-3D and have it carry over.

So if you had a cheap soundcard or onboard with dolby headphone, you could connect it with an optical cable to a standalone DAC and the effects would carry over. The soundcard wouldn't be used at all for sound quality in that situation. If you used a USB DAC you wouldn't go through the soundcard, and couldn't apply those DSP effects.

If your usage is a good chunk of fps gaming, I would suggest just getting a nice souncard like the Asus Essence STX. If you mostly listen to music, just get a standalone DAC and amp that will have higher quality.
