The AD2000X Hifiman 603 is still a headphone amplifier

Audio-Technica's headphones,It seems that the impedance is small,But it's not easy to push,hifiman603Push him,I'm afraid it's not even a pass,And colorful C4Push it,It's estimated that it can barely pass。

You can understand the maximum output power of this headset, and you can understand that this headset is also quite difficult to serve.

Whether the headphones are easy to push or not depends not only on the impedance, but also on the sensitivity, power, and so on.

Obviously, for a portable device like the Hifiman 603, it can be pushed to 50%, which is not bad.

Therefore, I think it is necessary to enter the second room.

About what kind of second room to enter, it depends on what kind of ** you listen to.

If you usually just listen to some pop, rock, DJ and other systems, a portable and compact second room is enough, like FiiO, Sony, Beye, etc. are OK.

But if you like to listen to the kind of classical symphony with a large arrangement, then the portable second room is embarrassing, and you need a desktop second room. However, I don't really know much about the desktop second room, but at least the price of more than 2000 can match your headphones.

The tuning of these headphones is actually really good, and it sounds very humane. Even if you can't push it enough, it won't make an unpleasant sound, but it will feel a little empty. After adding the second room, you will feel that the sound is very full, the details are rich, the high, medium and low frequencies are more energetic, and the sound is more emotional.

This may be the biggest role of the second room.

Regarding the role of the amplifier, there are a lot of related posts, and there are many people who have a thorough understanding of the amplifier, but there are also many people who have a biased understanding, and they can't be wrong, but it's like a blind man touching an elephant, just seeing one side.

Whether the earphone amplifier has an obvious effect involves many factors, mainly not to look at the headphones, but to see whether the sound source can fully drive the headphones.

If a source is of good quality and the output circuit is very good (equivalent to high-performance power output), then there is probably no improvement in sound quality (except for dyeing) with or without a headphone amplifier.

What kind of headphones and audio sources need headphone amps, I once posted a special post for reference: What kind of headphones and sound sources need headphone amps?

If the output capacity of the source is insufficient, or the output impedance is relatively high, or the ground loop is not handled well, the separation under load is reduced. The sound source has such and such shortcomings, especially the portable sound source, at this time, the earphone amplifier will be improved, and the amount of improvement depends on the output of the audio source, how much is the best demand for headphones, and how much is the listener's ear strength, and the quality of the type itself.

The same amp is plugged into different systems, and the difference in hearing improvement can be very large. Therefore, it is wrong to say that a certain ear can be increased by 30% under various sound sources.

Even with the exact same system, some people think it's only 20-30% better, some people think it's 100%, and some people think it's the difference between being able to hear and not being able to hear, which is normal. Everyone's preferences vary greatly.

This is like, HD580 and HD650, ** difference of thousands of yuan, some people think that the quality of the improvement value of the difference of thousands of yuan, some people think that only 20-30% increase, some people think that 650 is not as good as 580, it is normal.

In fact, there are some people who can't hear the difference between HD580 and HD650 blindly, pay attention to blind hearing, which is also normal, but it will make many people laugh. And people who can't hear the difference between the PX100 and the PX200 are not ridiculed much. In fact, the difference between HD580 and HD650 is much smaller than the difference between PX100 and PX200, but it can be played, and it is generally not the first fever, and the ear power is stronger.

I often see a lot of people talking about the quality of headphones, earphone amplifiers, and sound sources, in fact, the concept of quality is not unified, and there are indeed many people who regard the change of style as the improvement of quality, and the change of timbre as the improvement of sound quality.

The coloring of the ear amplifier will bring about the improvement of timbre, but it will reduce the sound quality and reduce the adaptability to **.

A good headphone amplifier should be more positioned on the sound quality rather than timbre changes, impedance matching, as little introduction as possible of coloring, and fully express all kinds of information through headphones. In particular, the high dynamics and large compilation** can test the ability of the headphone amplifier, and of course, the ability of the headphones and sound sources.

I think that in a listening system, the magnitude of the impact is:

**》Headphones》Audio source》Earphone amplification》Cable.

The headphone amplifier can have an obvious effect, provided that the **, headphones, and sound sources must have basic quality and cannot become a system bottleneck.

If people are also counted in the listening system, they must be ranked first in the formula.

Personally, I think pha3 is good and the voice is soft, I don't know if I like it.

Which front-end are you using now?

I haven't heard of AD2000X, and I can only give the landlord a reference here. If you deduct one by one from the hard quality, according to the situation of Japanese flagship headphones in the past, AD2KX is stronger than HD650 in sound field, positioning, and analysis. But it may not be the feeling of listening to the overall **,HD650The large compilation of the classical is really a must,I think the processing of low frequency on Senhai is the strongest,There is no one,That's a good low frequency。

But the landlord said to use the computer to push directly,Then don't really choose HD650,Maybe AD2KX can play better。

This price point considers the Q701, which is AKG. There's Sennheiser's HD598, which is not bad. It's not recommended to buy big headphones.,Because this machine plays a good general feeling.,It's not that you can't push it.,It's just that it doesn't seem to be free.。。

Or consider the plug is more to choose Shure's SE535, UE900, TF15, IE80, W4R, UM3XRX

If you wear headphones, consider Senhai's HD25 or Baia's DT1350 Sony's 1R can also be Personally, I don't recommend ESW9 In addition to the appearance In terms of sound, it is not a too cost-effective headphone.

For earbuds, you can consider the C5

Listening style? In-ear or head-weared?

Sanskrit ha-01 or **fax m1hpa

AD2000X can consider an MDAC5
