Hello everyone, I haven’t been sharing the speaker system with you for a long time. Do you remember that the new audio and video used Sony CAS-1, a small desktop HiFi bookshelves speaker ? After the system was updated, this product was not installed on the driver, and later I was too lazy to mess with it. The sound quality of Bluetooth is unbearable. The new audio and video usually has a USB flash drive to listen to. Recently, because the developer handed over the house in advance, the speakers that moved to the new house were obviously not enough. As a suitor to the spirit of fever supremacy, Xin Video has sorted out its solutions and is ready to start from the problems encountered and solve them one by one.
1. The current problems encountered and the ideas to solve the problems
Put aside the objective fact that CAS-1 is insufficient in this relatively large space. Recently, due to masks, I have more free time at home, and then I want to upgrade the bookshelf speaker system at home, because the system at home had encountered two relatively large bottlenecks that forced the new audio and video to upgrade. The first is that the traditional decoding amplifier requires a turntable or card to play music. The second is that it has been replaced with a new house. The high-frequency dynamic range and resolution of the previous system are somewhat insufficient in new rooms with large space.
If you want to completely solve these two problems at the same time, you need to update your entire HiFi system. New Audio and Video have watched a lot of decoding amplifiers, and there are quite a few products that can meet the requirements of new Audio and Video. It seems that everyone is gradually starting to invest some energy in intelligence and interaction in the era of streaming media. Faced with a wide range of equipment, New Audio and Video prefers manufacturers with strong brands and experience in developing amplifiers, rather than those manufacturers with excessive product lines. On the other hand, the choice of speakers should be aimed at two pain points. This passive speaker must at least have good sound quality, advanced technology and good reputation. The key point is that the box size this time cannot be too small, otherwise the problem will not be solved within a large space range.
In the end, the new audio-visual chose the combination of NADM10v2 and ELACBS283. This combination has been shared online, and the new audio-visual has also been deeply rooted in the field. Especially after feeling the charm of NADM10v2, the previous way of matching the turntable or digital broadcast and power amplifier can no longer be returned.
2. Advantages of NADM10v2 over traditional amplifiers
As mentioned at the beginning of the article, Sony CAS-1 can only connect to USB disk or other mobile phone devices with USB, while wireless connection only provides Bluetooth. The new audio and video uses an iPhone and cannot use an LDAC codec. This led to me not being able to get the best sound experience with its wireless Bluetooth feature. NADM10v2's built-in BluOSAPP supports WiFi and network cable connection. Access the network to obtain a powerful music library from streaming media. These streamers now have lossless, Hi-Res and even DSD-level audio specifications. This creates a huge amount of music resources, and also has a good quality assurance, which is more stable and sound quality than using Bluetooth connection. NADM10v2 also supports AirPlay, which is very convenient for iPhone users. If you have no confidence in the quality of the streaming media and your own network, NADM10v2 can also access music resources in the NAS (samba protocol) of the local network, which is very convenient for new audio and video. Of course, M10v2 also supports Bluetooth, but the new audio and video will not be used normally.
I don’t know if you still remember the RoonReady mentioned earlier in the new video, which is also supported in M10v2 this time. The new video of Roon gameplay will not be described here. If you have a Roon architecture at home, you can use M10v2 for more extensive extended playback. Overall, the M10v2 under BluOS has very rich and powerful functions, which can satisfy almost all your fantasies about a power amplifier, with simple software and rich features. The settings that can be set on the machine are relatively limited, and many settings need to be operated through the mobile app. Although there is a sense of separation in use, this is in line with the use of young users.
In terms of hardware specifications, in order to achieve powerful performance, the machine uses a dual-core 1GHz ARMCortex A9 processor, DACh is ES9028PRO, and ADCh is PCM1863. In the digital amplification function part, the M10 uses the exclusive HybridDigital technology of the NADMasters series and uses the HypexNcoreNC252NP Class D amplification module. From the back of NADM10v2, you can see various input methods of NADM10v2, including network interface, HDMI, optical fiber port, coaxial port, analog input, etc. Here comes the point. The M10V2 uses the famous HypexnCore amplification technology, which can provide advanced performance (high efficiency and powerful power) and the ability to easily drive any speaker. It can display the rich details and dynamics of music in a vivid and realistic way. This output interface supports bridging, which is the focus of the new audio-visual selection of M10V2, because this can help users to be more relaxed and convenient when matching passive speakers.
NAD patented technology - PowerDrive airbag power drive also did not fall below this time. By adding a second high voltage to the high current power supply, as the role of backup power supply , when the gain and frequency response of amplifier is increased, the saved power is released. , and there is also the DiracLive room correction function. Do you still remember the ADC chip mentioned just now, which is mainly used for the implementation of this function. The user needs to connect the randomly included test microphone. DiracLive can guide the operation to test 9 points in the space to fully understand the frequency response of the status of the space, and display the results obtained by the measurement in a graphical manner, so that people can clearly compare the effects of correction before and after . After that, you can directly upload the results calculated by DiracLive to M10v2 (can store 5 configurations). This function can help the new audio and video realize the impact of room size changes on the sound experience.
To summarize, M10v2 can be said to be a network decoding amplifier born for "pushing streams". Many functional designs are optimized to cater to the lifestyle of young people today. It can be said to be a "Dream Love Player", but the price is a bit painful. Fortunately, the entire machine has a high evaluation on the Internet in terms of functions and specific sound performance.
3.Speaker selection
Due to the space limitations in the study, passive study speakers should be given priority. Yili ELAC is not a miscellaneous brand. As a speaker brand with a century-old history, it still has only launched a product that is not very good. The BS283 selected for the new audio and video this time is a bookshelf speaker designed for modern home furnishings. The black piano paint combined with the excellent quality workmanship of Yili really makes people feel very tasteful.
BS283 uses the fifth generation JET jet tweeter unit, handmade in Kiel, Germany. The new audio and video attaches great importance to the dynamic range of high frequencies. JET5 can transmit ultra-high audio signals with a frequency of up to 50,000Hz, and can be as high as 100 degrees in the sound propagation angle. We looked closer through the macro lens and saw that it was actually the aluminum alloy film folded repeatedly to create a structure similar to accordion . The principle of sound production is to squeeze the air into the gaps in the wrinkled diaphragm to generate sound waves. Theoretically, there are two advantages: the first is the ultra-wide diffusion angle of the sound wave, and the second is the larger sound area, which can reproduce larger sound pressure. From a theoretical perspective, JET is the best treble monomer design. The woofer is made of a 150mm composite aluminum alloy material, and the surroundings are made of cast aluminum frames. The rigid but lightweight material ensures mechanical stability and lays the foundation for highly accurate sound reproduction. The reflective guide holes are retained at the bottom to ensure the airflow space of the horn and enhance the bass atmosphere, thus achieving the design of the small box and the design of low-frequency and volume. Noemx wave, Hi-end foam carton is used on BS283.
When you come to the back of the speaker, you can see two terminals with treble bass, which is also a symbol of high-end passive speakers. It also previewed that this is a bookshelf speaker that is not very good to drive.Do you still remember the HypexnCore technology supported by NADM10v2 just now? The new audio and video also took this eye on this and dared to be assured to match it with BS283.
4. The actual listening experience of the entire system
First, let’s introduce my listening environment. I listened in a new study room of about 17 square meters, because next to the study is a north balcony (transformed from the equipment platform room sent by the open merchant). The sound insulation effect is not very ideal, and the noise outside is occasionally noisy. I have tested it to use it in the living room (the environment where the picture is taken), and the sound is much more stable than in the study, and the sound field is more realistic and natural. Adjust DiracLive in the new room, and the new audio and video uses smb to connect NAS, applemusic to push streams, etc. to serve as the audio source. The power cord is the Van Denghao silver cord and the speaker connection cord is the most commonly used single crystal copper silver-plated wire in previous reviews. These lines are of some help to the quality of sound. Compared with the original power cord, the sound details and the looseness of the sound field are improved. This single crystal copper silver-plated wire is also more beautiful than the high frequency of some ordinary oxygen-free copper speaker lines, and the low frequency details are richer.
After introducing the listening environment, the dynamics and control of the overall sound of the new audio and video team are the most satisfying things. The sound style of BS283 combined with this system is particularly prominent in high frequencies, the control power of low frequencies is great, the resolution of the three frequencies is very good, and the sound field is loose, natural and atmospheric. With the blessing of this single-crystal copper silver-plated wire, after half a month, there is no harsh sound in the high frequency, and the delicate feeling of the medium frequency will gradually become prominent. Because the sound coverage of this speaker is wider than that of other speakers, especially the design of the high-frequency unit allows the entire speaker to face 100°. The distance between the new audio and video here is about 1.2 meters away, because this set of speakers is not particularly suitable for near-field listening. This set of speakers is quite suitable for sitting on a lazy sofa and slowly enjoying afternoon tea time to listen to.
Compared with the Sony CAS-1 I used to have, the mid frequency in the new system is fuller, the sound image is very outstanding, and the high frequency also has more outstanding details compared to the CAS-1 in low volume mode. For example, when I listen to ",000 reasons for sadness " by Jacky Cheung , the volume of M10v2 is adjusted to about 40%, and the vocals in the mid-frequency part will be full of magnetism. Jacky Cheung's unique singing voice is fully displayed in this system, and his control of the sound is very well controlled. If you continue to increase the level, the volume of the M10v2 will be adjusted to about 60%. The control it provides is just right, which will not make you feel the high frequency harshness, nor will you feel the low frequency thrust head. It can meet the user's listening needs in a larger space, and the sound field image will be more solid and clear. Keep the volume of M10v2 within 4/5 volume, and the overall imaging of the entire listening system, the resolution of the medium and low frequencies, and the transient details are also in the best state. In other words, pairing BS283 with M10v2 can be said to be a very good streaming amplifier combination, and there will be no distortion regardless of the sound size.
In terms of mid-frequency and high-frequency styles, BS283 is more focused on the resolution and large dynamic style. This is exactly the shortcomings of CAS-1 in high-volume mode and the reason why the new audio-visual wants to replace the device. The M10v2 sound ensures good tension. Both the mid-frequency and high-frequency are more direct, and the transient is relatively fast. However, the silk film treble still achieves a smooth style and good resolution in small sizes, while providing a good sense of sound layering. The low frequency produced by the entire system is relatively clean, especially at medium volume, the low frequency volume and details are very good. For bookshelf speaker products and even some floor-standing speakers, such low frequency style and control are good enough.If users find that the low frequency sense of control is slightly worse when using it on the desk, they can be encouraged to place it a little bit when installing it, and then increase the height of the seat where they listen to the song as much as possible. This purpose is to attenuate the low frequency, because in a near-field listening environment like a desk, the low frequency of the entire system is more "satisfactory". Of course, incorrect positioning and deviation from the position of the emperor's throne will also affect the effect of the sound field. For some serious music , doing so will affect the listening experience.
Right, try not to match BS283 with oxygen-free copper audio cables or poor-quality single crystal copper wires, because this will have a greater impact on the resolution and sound field of the sound. The heat generation of M10v2 is not large, but do not use debris to block its heat dissipation and breathable holes. Let’s summarize the sound of this system, which means that the sound field is loose and the analysis is very strong. Excellent high-frequency dynamic range, excellent low-frequency control power, and high medium-frequency density. M10v2 is easy to use and streaming media push and streaming is easy to deal with. This is almost one of the best combinations of streaming gameplay.
5. Summary evaluation
Quoting a friend of the new audio and video team, it is that the system seems to be full of money. Indeed, Teacher Xiao Zhuo from the new audio and video team usually only plays with headphones and portable players. It is just that "it's great to have money" when listening to this speaker system. To be honest, for most people, the price of this system is close to 40,000, which is something that many users cannot afford in the current environment. However, with the increasing requirements for quality of life, the Internet's penetration of traditional fevers and the changes in people's requirements for sound, it is more practical to have this system than to spend 20,000 yuan to buy earplugs and 20,000 yuan to buy a player. Moreover, the impact of speakers on hearing is much smaller than that of headphones.
so new audio and video is recommended here to those who have houses with certain economic strength or users with high requirements for life taste to try out such a listening system. I wonder if you are also moved by this combination after seeing this? Here is the new audio and video. If you have any questions about the use of M10v2 or BS283 or what you want to ask, you can leave a message to me below the article, and I will answer your questions in a timely manner.
