It seems that the last purchase link is not displayed. . . There are a lot of people who are asking here to add it, is in the "Audiovision Master Mall", a professional online audio product/service mall.
British NAD D3020 amplifier home audio HIFI fever digital amplifier avcm.com direct link Recently it was time to itch, and moved a NAD D 3020 integrated desktop amplifier back home to upgrade the surface acoustic system that had been using multi-year tables.
Pioneer AX5i and Yinxin computer chassis
This is a signal source and power amplifier before the upgrade, is not a slight domineering side leakage. Do not underestimate this pioneer AX5i old A / V amplifier, although it has fallen to build a temporary desktop system, but then the vanguard of the flagship, THX certification, the famous British recording studio Air Sudio tuning. However, the excessively large size and weight destined that it is not a qualified desktop amplifier (if it is used as a home theater, the effect is still just except HDMI).
Onkyo D-S7GX
Speakers: Onkyo's D-S7GX bookshelf, which was originally a companion speaker for the mini-system, is now being used for other purposes. Do not look at this little guy, but it is 85dB sensitivity / 4 ohm impedance configuration, the general power amplifier really waits for it, even the big head above must open to a higher volume to force it out. Don't ask me the price, it seems like a pair of 100 yuan 
This is a picture of the upgraded desktop system. It is not only the appearance of reborn, but more importantly, the convenience and function have been greatly upgraded without sacrificing the sound quality.
See here, it is estimated that many valued friends will have a question mark in their heads: Isn't that a desktop system? Why not choose a pair of active desktop speakers, such as Swans, but such a small price is not cheap?
Well, it seems necessary to talk about the reasons for choosing it. And how to set up an easy-to-use, cost-effective music system at home.
About the NAD brandSpeaking of NAD, I am afraid that for the average consumer is not a straightforward brand. However, in the eyes of audio enthusiasts, NAD represents a cost-effective and powerful speaker drive capability. Looking back at the NAD 3020, which ranked in the Hi-Fi Fever List, the price is both low (£80) and power (20W@8 ohms), but because of its superior sound quality and powerful speaker drive Force became the most famous and best-selling amplifier in history.

When he was on the London debut, he tamed the famous Linn Isobaric speakers and became famous.

As a follow-up model of such a famous and even legendary power amplifier, what kind of skill does the D 3020 rely on? A body that is much smaller than its predecessor (1.38 kg VS 5.3 kg), inherited after 30 years. What is the name of 3020?
In fact, most of the time, the answer is not official propaganda or media evaluation can bring you. Xiaogan is often not too concerned about the manufacturer's promotional materials and will only retain the parameters for reference. Officials like to give some publicity slogans, or a function/technical pile-up. As to what can be brought to consumers - the most realistic problem, it is difficult to get a definitive answer based on the professionalism of the user. As for the media evaluation, apart from a few photos and some fixed test items and praise words, there is not much to see.
how to chooseWhen Xiaochao selects a product, it generally considers whether the usage scenario of this product is attractive enough. The usage scenario can only change from idea to display after it is actually used. For audio products, the manufacturer's publicity will focus on how the sound quality is. In fact, for ordinary consumers, sound is the most subjective thing, different listening environments, different equipment, and even different moods will make it come out. The difference between the sound of the same equipment is tens of thousands of miles. Therefore, for the vast majority of consumers, the selection of consumer electronics audio products (if the D 3020 can be regarded as), the most important point of consideration, entry point, is the product "can be competent enough for specific use scenarios."
So for the D 3020 such power amplifier products, Xiao Shao choice, the most important thing to consider the parameters of the equipment it? There are three: First, the brand (quality and sound orientation), the second is the function (in most cases, the function determines the use of the scene, and the function is often a fixed property of the product, can not expand on their own), and finally the power (for reference, need Actual audition).
Out of the boxOuter packaging, simple kraft box, NAD red logo is very conspicuous. The packaging is also relatively small.
There is also a package inside, black carton hot stamping.
Open the black package, the inside is very simple, a manual, an accessory box (power cord, remote control, etc.), D 3020 body in that black velvet bag.
Take out the body, not big, still a simple line, the atmosphere of black. The NAD logo is printed on the side, and the long, meshed vents are below.
A family portrait. Remote control, battery, footer, fiber optic round adapter, power cord.
Under normal circumstances, Xiaochao got this type of product, the first thing is to look at the end of the product (ju) mouth (hua). Basically, you can roughly understand what kind of features.
The rear view is basically a clear function terminal. There is something to say here:
1. The Bass EQ button in the upper left, this button is intended to compensate for the bookshelf that is often associated with this small amplifier, due to the unit and box volume limitations, and the lack of bass. By pressing this button, this function can be turned on (simultaneously displayed on the panel), and the bass will be fully boosted by 6 dB. See if everyone here heard the voice of NAD engineers: "Don't blame me for low frequencies, blame the boxes you don't use."
When using a stereophile evaluation, the on/off curve of the BASS EQ was measured with the instrument. It can be seen that the main lifting center point is around 80 Hz, which is also the place where the lower limit frequency of the general small bookshelf goes up a little.

2. 12V trigger, see the port of 12V TRIGGER IN yet? The average user may be unfamiliar with this interface. In fact, this interface is very common in A/V products such as projectors, rear amplifiers, and electric projection screens. Function is used to achieve linkage: simply open the amplifier, connect the 12V triggered equipment will automatically start, shut down, automatic shutdown, a convenient function. How to break the 12V trigger line at home? Don't worry, an ordinary 3.5mm audio cable can be used instead.
