Although I have many earphones, I only use speakers to listen to music at home. I don't know if anyone will have the same feeling as me - listening to music with earphones or earplugs is totally different from using speakers. Wearing headphones or earplugs to listen to music, the sound field is directly built in the head. The outside world seems to be isolated from itself, falling into another world, and many things around suddenly disappear. With speakers, sound builds a sound field outside your body and then reaches your ears. I call earphones, earplugs, speakers, players, power amplifiers and other devices "music containers".
This article is from: Ainongji Digital Alliance Contribution from member Xiao'an (Weibo @ most digital Xiao'an).
As a listener, I think it is necessary to have a good set of "music containers". This is a bit like drinking red wine. The cup is very particular. The ancients also said that "the luminous cup of grape wine" said that the luminous cup of red wine was very beautiful; When we put red wine in a cup, we can feel the cool temperature of the wine, see the beautiful color of the wine, smell its fragrance, and hear the crisp sound of the cup when we touch the cup. That is to say, the good "container" enables us to enjoy not only the taste, but also the touch, hearing, smell, and vision when we drink.
It seems that there are some similarities between the two theories when it comes to listening. Turn on the CD player, take out your long cherished album, look at the fading cover, insert it into the cabin, and start to hear the whine of the accelerated rotation of the disc. Press the play button, touch the volume knob to turn up the volume, and stare at the black speaker, The music starts slowly...... This process is very enjoyable.
The most important thing is that when the volume is high, you can feel the sound waves driving the air to vibrate, the feeling of coming at you. Sometimes you can even feel the hairs on your skin shaking slightly. This experience is fascinating!
Listening to music with earplugs or earphones is very similar to using a "straw" to directly suck red wine from a bottle. Many of the above feelings are basically gone. A pair of good speakers, I think, are similar to the "glow in the dark cup" containing grape wine. What do you think?
Anqiao CS-N755 Desktop HiFi Audio Unpacking
The set of stereo set introduced to you today is from Onkyo Onkyo, a Japanese manufacturer. Listeners who often read my posts will know that Onkyo has earplugs and earphones. If you have a careful understanding of the manufacturer's history and its products, it is not difficult to be attracted by it. The company founded in 1946 has a history of 68 years, It is one of the few manufacturers that still insists on launching new HiFi class power amplifiers.
About 10 years ago, when VCDs were very popular, many manufacturers were producing Mini audio, including Japanese manufacturers Sony, Panasonic, JVC, Kenwood, Aihua, Tianlong, Anqiao, etc. At present, few manufacturers are still updating their production lines. After comparing the products of several companies, it seems that Anqiao's products are more desirable, and they are also better matched with the devices on hand.
OnkyoCS-N755 is an updated product of Anqiao recently. It belongs to the second flagship in Anqiao's desktop Hi Fi audio system. The price in mainland China is more than 5000 yuan, and the price of flagship CS-1045 is about 8000 yuan. This set of CS combined audio is composed of the host CR-N755 network CD receiver and 2.0 passive audio D-055.
Accessories include indoor FM antenna/AM ring antenna/speaker cable and cork foot pad/manual remote control, etc. The special thing is this remote control board, which is very long, longer than the remote control board of ordinary TV sets. The physical object is very impressive, the layout of keys is loose, and the feel is very good.
Anqiao's CR-N755 host must be equipped with an external antenna before receiving AM FM radio, but it is not necessary to expose the antenna high. It can also have a good listening effect on the back of the machine.
Package host CR-N755 CD network receiver parameters
Starting from this year's CR-N 555 console, Anqiao changed the front panel design to a flat panel design. Most of the previous Anqiao desktop audio consoles were concave and convex front panel designs. After being changed to a flat panel, they looked more like the appearance of their HiFi power amplifiers. In the past, the middle end models of Anqiao consoles were mainly made of plastic, but now they are also changed to metal panels with better texture.
In Japan, the main unit and speakers of Onkyo desktop audio can be purchased separately and matched freely, but only sets are sold in the Chinese mainland market. I saw a CR-N755 main unit with a black panel in Japan and Asia, and the price was only 2000 yuan. However, the gross weight of a full package of 7kg plus 20% of audio product tariffs is estimated to cost people knees!
It should be said that this CD+MP3+radio+power amplifier+network receiving system is one of the best desktop HiFi audio systems on the market at present. The N755 has won several awards since its launch in 2013.

From the practical point of view, this host can support too many media forms, which is completely "one mechanism hegemony". It can play music CDs, CDs and CD-RWs, so that my CDs will not be wasted.
The CR-N755 has an RJ45 network cable interface behind the body, which has obtained DLNA1.5 certification. Because of the network support, your phone and the CR-N755 can push music to the host through the iPod touch/iPhone and the Onkyo Remote program on Android phones under the same gateway, including some third-party Android playback software we commonly use, such as QQ Music's "Qplay" The function can also push music to CR-N755 for playing. In addition, this machine can also purchase Anqiao's UWF-1 wireless network adapter and UBT-1 Bluetooth USB adapter.
There is also a USB interface on the front panel. The CR-N755 can play the music in the USB flash drive. When playing back audio files via the network or USB flash drive, MP3, WMA, WMA Lossless, FLAC, WAV, Ogg, Vorbis, AAC, LPCM, Apple Lossless, and DSD can all support, especially many lossless formats such as DSD. This will satisfy the fans.
This USB interface can also play MP3 and AAC audio files stored in iPod and iPhone, and charge the device at the same time. If you plug in the UBT-1 Bluetooth adapter of Anqiao, check that the price in Japan is less than 100 yuan? With the codec technology and Bluetooth 3.0, you can play Bluetooth pairing. However, in front of such a beautiful host, no one may want to insert a USB stick. There is another USB interface on the back of the machine.
The DAC chip configured on the CR N755 is the WM87188718, which supports 192K/24 Bit audio. It is the previous flagship of WOLFSON and has good quality. Many PC independent sound cards use this chip.
The interface on the back is too rich! By comparison with desktop audio consoles from Sony, JVC and other manufacturers, you can see that there are few host interfaces from other manufacturers. Anqiao, a host integrated with playback, decoding and power amplifier, is also equipped with interfaces for all three devices. The main input and output interfaces are: digital audio input (optical fiber and digital coaxial), three groups of analog audio input and one group of output, and the other are RJ45 interface, USB interface, antenna interface, AUX IN interface, etc.
The transparent gold-plated banana plug speaker terminal material is not as flashy as the all metal terminal, but it is also a relatively advanced configuration. The accompanying audio connection line is a relatively thick copper wire. In addition, because there is a group of RCA output interfaces, you can connect another pair of speakers. The 30W single channel output power is more than enough to push the ordinary 5-inch passive speaker.
There is also a 3.5mm audio output interface on the front panel, so that you can push the high impedance large earphone. The output parameters of this interface are unknown, but I have tried with the AKG K701, and the volume only needs to be turned on to about 40%. With this front 3.5mm interface, you can use it as a desktop ear amplifier.
As for the touch of the keys, the large volume knob on the host is undoubtedly the best. The damping is moderate. When you turn it, you can feel a slight sense of relief. If you have nothing to do, you just want to turn it a few times. The control of the previous song and the next song is realized through a small knob, which is much more convenient than the traditional single return button in fast forward selection. Other control buttons are designed to be convex, and the click sound is similar to the mouse button.
Introduction to CS-N755 package passive speaker D-055
The model of the CS N755 package speaker is D-055. There is no special design on the appearance. The loudspeaker unit inside can be seen vaguely through the dust screen on the front panel. The sound boxes in Anqiao are more beautiful. I think the appearance design of D55EX and D112EXT has a rectangular guide hole under the sound box, which is very impressive. In Japan, you can choose more advanced D55EX and D112EXT to match with this host. In China, there is only D-055 set, so you can only say -- alas!
This pair of D-055 speakers weighs 3.6kg each, which is relatively light. The box made of medium density fiberboard is covered with a thin horizontal stripe texture panel. The leather feels good, and the dust cover can be easily removed.
The speaker design adopts the technology called 2-way bass reflection by Anqiao. It is said that there are many boxes in Anqiao's speakers, including a 12cm N-OMF cone basin unit for the mid bass unit, which is commonly referred to as a 4-inch unit, and a 2.5cm soft dome unit for the treble.
Frequency response: 55Hz-35kHz Frequency dividing point: 2.5kHz Output sound pressure level: 83dB/W/m Maximum power input: 70w Impedance: 4 ohms.
The 4-inch N-OMF cone basin unit, "N-OMF", which is called "Anqiao microfiber" in the official data, is a durable material, including a layer of molded aramid material and lightweight non-woven cotton fiber, providing the hardness required by the vibration basin to complete rapid and accurate response. This material works in series with the bullet type phase cone, which can effectively absorb redundant vibration. In addition, each speaker also has a distinctive soft dome top tweeter unit, so as to better reproduce the high-frequency part of the sound.
First, I think it's very beautiful. But I prefer the black host to the box. Unfortunately, there is no black host in mainland China.
This set of speakers is still beautiful at home. Anqiao's desktop HiFi sound system can be extended by purchasing other models, such as Anqiao's playback base ND-S1000 with iPhone interface, and a DAC 1000S power amplifier can be added, so that the system decoding can be upgraded to a dual parallel WM8740 DAC. These expandable machines have the same size, similar appearance design style, and will be more uniform when stacked.
System configuration and I/O functions
CR N 755 digital audio input adopts 2 VLSC circuit, which can significantly reduce noise. The Hi Fi amplifier is a three-level inverted Darlington circuit, and the enhanced HICC (instantaneous current capability) speaker drive capability is the guarantee of high-quality music for this host. In addition, Anqiao uses a wide range amplification technology called WRAT to ensure distortion control during amplification. Some power amplifiers will hear Zizi current noise when they are connected to the passive speakers. The filtering circuit is not well done, and there is no way to talk about high-quality sound. The circuit design of CR-N755 should be very good, and the noise is basically inaudible.
I finally put the CS-N755 next to the computer. Because there are many audio sources and output ports, I think it is quite practical. A little trouble is that you need to turn on the host power of the N755 every time you turn on the computer. If your computer has no audio signal input to the N755 host for a long time, it will automatically stand by to save power. You need to turn on the switch again. The power consumption of the whole system is 74W, Standby power consumption is 0.26W.
When connecting to the PC host, you can use the 3.5mm audio port to switch to the RCA port. If there is a fiber interface, it is the best. Many inexpensive independent sound cards or some advanced motherboards have fiber output interfaces. Plug them into the N755 host, and then switch the inPut input channel.
I have an Anqiao ES-HF300 headphone, which can be plugged into the 3.5mm audio interface on the front panel. If the headphone is plugged in, there will be no sound in the speaker. This host only needs to turn the volume knob to 25% to drive the Anqiao headphone, The sound of the N755 with this Anqiao headset is heavier than that of an ordinary MP3 player, but the high and low tones of the N755 can be adjusted through EQ.
Like most traditional audio systems, the CR-N755 does not support multi channel mixed output. I prefer to listen to the radio, but if I listen to the radio on the N755, the operating sound of the computer will not be heard. It's a little pity here. AM and FM support 40 channel storage, FM listening effect is very good. The antenna can be hidden behind the machine. The AM antenna designed by Anqiao is a little large, which will slightly affect the overall visual effect after installation.
Anqiao CR-N755 is called the "network CD receiver" on the official website. Supporting DLAN protocol for network playback is a major selling point. After connecting the CR-N755 to the LAN, Anqiao Audio can be accessed on other computers to push music to it for playback.
On iOS and Android platforms, Onkyo has launched a mobile terminal playback and management software - ONKYO REMOTE. As long as your mobile phone and tablet are in the same LAN as the audio of Onkyo, you can use ONKYO REMOTE to play wireless music, and realize advanced functions such as input port management and sound effect settings, which can basically replace the remote control panel.
The playback software on many mobile phones also supports the DLAN protocol. For example, Sony's Walkman Android playback software can establish a link with CR-N755 to play music through the Throw function. Other third-party playback software, such as the Qplay function in QQ music player, also has the same effect. It is somewhat similar to the function of Bluetooth speaker, playback control The next song switching and other operations are also very responsive.
Introduction to CS-N755 Audio System
This set of Anqiao stereo was received on December 24, which should be regarded as a Christmas gift. It burns for about 10 hours every day. When working in the daytime, the FM radio is turned on, tuned to the music station, and then played music at home in the evening. The time should be about 300 hours. When I first got it, I felt that the sound was tight, especially the mid high pitch, even a little dry, Pay attention to the change of sound in daily use, and begin to feel that the sound is getting better.
The sound impression of this stereo is the same as that of its appearance. It is "exquisite" in two words. The sound of Anqiao combination should belong to a relatively clear style. The treble and bass are more prominent, and the mid frequency density is slightly less. Like most 2.0 speakers, many people who are used to the so-called "subwoofer" may think that there is not much bass in this set of sound.
But compared with the general 2.0 speakers, I think the D-055's bass is more prominent, which is mainly reflected in more overtones, good sense of diving and layering, but less powerful sense of impact. The 4-inch N-OMF (aramid material and non-woven cotton fiber) cone basin unit used by Anqiao is more elastic and textured.
Because of the characteristic of more bass overtones, the sound field is very wide and deep, that is to say, the horizontal and vertical sound fields are good, and the sound atmosphere is sufficient, but the mid frequency density is not much. In addition, the sense of power of the bass is less than that of Shaoanqiao. This combination sounds like singing in an open room, rather than the feeling of thick, powerful and strong voice, The voice is relatively clear and beautiful, and the overall sound atmosphere is good.
I have used two other pairs of desktop speakers for comparison, one pair is Sannuo N35 and the other pair is Huiwei M200MK Ⅱ. The three speakers are connected to the main unit of Anqiao. The M200MK Ⅱ has a high density of mid and high tones. I feel that the human voice is the most full, mid and high, and the mid and high frequencies are closer. The high tone stimulation is sufficient, and the bass overtones are less. The sound field is not as large as the other two speakers. The sound style of the Sannuo N35 is somewhat similar to that of Anqiao. The bass is more powerful than Anqiao D-055, but the overall sound level and details are obviously inferior to that of Anqiao. Moreover, the low-noise of the Sannuo N35 is obvious. In terms of the basic sound quality of the speakers, the other two speakers are inferior.
So I think the main style of the Anqiao CS-N755 audio set with D-055 audio is the HiFi listening style. It emphasizes the three basic qualities of sound detail, sense of hierarchy, and positioning. The distribution of three frequencies is basically concave between two high schools. The treble is not very stimulating and natural and sweet. The density of the mid frequency is slightly less, so the mid high frequency sounds are clear and beautiful, The bass has more texture, more overtones, and a wide sound field. The atmosphere is good when listening to music. The vocal performance of the music is natural and the overall sound is clean. If you prefer rock and roll, you may feel weak because you have less sense of percussion.
CS-N755 Desktop HiFi Audio Experience
The advantages of this system lie in its rich input and output channels and scalability. I think the host is more cost-effective than the speaker. It has very good sound quality and rich functions. If you don't mind whether it has network playback function, you can choose CS-555, the predecessor of CS-N755, The CS555 has no network playback function. Other configurations are similar to the CS-N755. However, the network playback function is still very good and convenient to use. Especially when you use this stereo as a bedside stereo, you can play music without connecting.
I believe that many people will find it difficult to build a desktop audio system. It is difficult to use a CD player as the front end, a computer as the front end, or a whole player with a hard disk as the front end. The front end has solved the problem of decoding power amplifiers, which is more troublesome. Which is better to choose, such as built-in sound card, external sound card, USBDAC, etc? Anqiao's desktop HiFi combination audio is easy to solve this problem. It not only has CD playback, but also supports external storage. The computer optical fiber port, network playback, and other inputs are quite complete, so it is very practical to use one machine for multiple purposes. In addition, this audio host feels really "decathlon". It is easy to push up the headset. I don't need to say much about the appearance. Even if I listen to the radio, it seems full.
In terms of sound, I think if the player is not too picky, the sound of the D-055 sound box is enough. The sound style of this sound box may be more "beautiful and exquisite". If you want a stronger bass, you can add a bass speaker to your system, or directly replace the D-055 sound box. If you have money, you can consider that the flagship CS-N1045 of Xia'anqiao Family is equipped with a 12cm OMF woofer. It is said that the bass will be more surging.
