The German Eili DB52 paired with the British D3020, sings the good voice of China_Original

Some time ago, “Cardinal” Zhou Hongyi broke the news, saying that his home theater is worth tens of millions, which shocked me and other civilians. Although we cannot buy a set of expensive speaker equipment like Mr. Zhou at every turn, it does not prevent us from listening to the “good voice of China”. Today, I will share with you a German Ili DB52 passive bookshelf box with a British NAD D3020 amplifier. What resonance will the products produced by these industrial powers resonate together, let’s take a look?

–

As a well-known German audio manufacturer, ELAC has a wide range of product lines in the audio-visual field, and its products also carry the rigorous and honest style of Germans. Yili DB52 is a redesign of Debut2.0 on the basis of the original product. The requirements for sound quality are almost harsh. Once launched, it has set off a revolution in the high-end speaker industry, because no product has ensured such high quality before. At the same time, the public’s affordability is also considered in terms of price.

The Yili DB52 uses black peach-colored medium-density fiberboard as the box, and the thick material can reduce the resonance during playback. The size of 341mm in height, 180mm in width and 234mm in depth is relatively compact and powerful, with a typical German style with sharp edges and corners. The frosted solid wood veneer will not easily leave fingerprints and imprints.

The Yili DB52 uses a front guide hole design, which is placed close to the wall without affecting the sound performance. I noticed a detail in the basic product information on the back. The Debut series was designed by Andrew Jones (it is understood that since he joined ELAC, he has redesigned all the speaker cabinets and components of the Debut series). His name is marked on the first line of the product information.

The two metal 5-way metal terminals on the back of the box have positive and negative signs at the bottom, and red and black signs at the bottom of the copper pillars to facilitate corresponding wiring.

The Yili DB52 has a built-in 1 inch silk dome tweeter and a 5.25 inch bulletproof cloth cone woofer. This combination can more highlight the performance of the DB52 in the mid- to high-range unit. The precision-designed crossover is the secret weapon of high-quality sound, allowing the sound details to be displayed more abundantly and delicately, especially the reinforced wooden cabinet, which can effectively eliminate sound interference and bring us a purer sound.

For the tweeter part, the Yili DB52 uses a 1-inch spherical waveguide silk film dome tweeter, with a frequency response of up to 35000KHz, creating a more realistic high pitch. And its spherical waveguide technology can improve the directivity and eliminate the sound diffraction problem caused by the traditional speaker cabinet.

In the woofer part, the Yili DB52 adopts a ballistic fabric cone, which can bring excellent strength and damping characteristics, as well as a wide and smooth audio response, so that the low frequency performance is better and the sound details are more abundant.

Next, let’s take a look at NAD’s D3020, which is a desktop digital power amplifier. In addition to supporting passive speakers, it can also support daily audio peripheral devices such as TVs, tablets, mobile phones, record players, and headphones.

–

The size of NAD D3020 is 219mm long, 186mm wide, and only 58mm thick, which is not much bigger than a mobile hard drive. There is only a large volume knob on the front, a 3.5mm amp output port, and other buttons are designed with OLED touch, free from the shackles of physical buttons. It can also be placed upright, saving more space.

–

After the product is turned on, it directly displays the current input source and volume, which is intuitive and clear. Tap the top S button to select the input source, and turn the stepless hydraulic volume control knob to adjust the volume as you like.

The back interface is very complete

Back interface description:

NAD D3020 has a unique skill: airbag power. Simply put, it can adjust the power output of the internal circuit according to the impedance of the audio device to ensure the best output support for the audio device, the output is more stable, and the driving force is stronger.

–

NAD D3020 V2 uses a Class D amplifier circuit, with a standby power of only 0.5W, while the output power can support 30W per channel. And D3020 has BassEQ to enhance the bass effect, which can provide a moderate amount of low frequency gain for small bookshelf speakers. With the DB52 of ELAC, it complements each other.

With the combination of ELAC DB52+NAD 3020, the overall sound is relatively neutral, with a clearer sound and a sense of penetration. The high frequency part, because of the 3.5KHZ response, can easily rise from the low frequency to the majestic scene, while the vocal in the middle frequency part is a little thick, and the low frequency part, with the D3020DE BassEQ enhancement effect, the performance is also Not bad. In short, the strength of all aspects of this combination is in place, and the ears can feel a stretched and elastic music experience, which is not experienced in the various Bluetooth speakers and headphones used before.

The author belongs to Xiaobai who is just getting started, and has no ears to distinguish the more detailed sound performance. Although such a set with a total price of around 6,000 is a bit expensive, it is considered an entry level in the Hi-Fi field. But just because it is just getting started, it is suitable for novices to “grind their ears”. Moreover, the combination of passive bookshelf box + desktop power amplifier can connect to various current equipment and facilitate future product upgrades. It should be noted that this set of products is not suitable for daily use as computer speakers. Generally speaking, as a young person who wants to get started, I personally think it is a more suitable choice.
