Following the German AVM CD 3.2CD player, the editor comes to recommend a combined power amplifier to match it. The protagonist is Evolution A5.2, a product of the same AVM.
Compared with the previous generation, A5.2 has great improvements in all aspects. First of all, it has a lot of refined appearance, elegant and noble appearance, very German style. There are two large knobs on the aluminum alloy panel to control the volume and information respectively. Source selection, the large display in the middle is both beautiful and practical. The most special is still the exclusive feature of AVM, from the front panel, top panel to the side panel, there are no traces of screw holes. The elegant appearance and the functions of operation and use are perfectly combined, so that the circuit inside the chassis can be matched with the perfect and accurate aluminum alloy casing.
A5.2 is a very versatile and multi-functional stereo integrated power amplifier. It has the evolution route and functions of the Evolution fashion series. Its core design values ??are much the same as its series models A3.2 and PA3.2. Common similarities: 5 groups of high-level input terminals, 2 groups of front-end output terminals can be connected to a rear-stage power amplifier with higher output power.
The A5.2 backplane has three plug-in expansion modules: if you are a vinyl turntable user, you can install a high-quality moving magnet/moving coil phono amplifier; or if you want to listen to the radio, you You can also add a tuner module; the most important thing is that for CAS/FAS players, you can configure a USB DAC module. The high-end AVM optional equipment is exactly the same as the USB module used in the high-end front-end. It has strong functions, not only USB input, but also optical and coaxial digital input. This optional digital input module does not require an external driver for the USB part, but AVM has also designed a 24bit/192kHz upscaling process. The USB acceptance is more compatible to 16bit/48kHz. In theory, this setting is not only convenient for use. In addition, it sounds better than a normal USB module. 1 set of external input and output terminals, which can be connected to an external audio processor or active subwoofer. Concise and easy to understand catalog function according to personal preference(Input name, sensitivity… etc.), Set each input parameter independently. Simplify complex processing concepts. In this way, A5.2 can provide pure, long-term joy and fun of listening to music. The most distinctive feature is that this A5.2 integrated power amplifier does not require additional installation procedures, and the operation is very convenient and easy to understand. This is also one of the most popular elements of A5.2.
The output power of the two sets of speaker outputs of A5.2 is very powerful. In the case of 8 ohm load, you can get a strong output power of 200W per channel, and you can get a power of 350W at 4 ohms. You can use it easily. To drive two sets of different speakers separately; you can also use a dual amplifier-two-wire connection to drive the high/low end of the same pair of speakers to make them play the best sound performance.
The A5.2 signal amplifier output stage adopts the vacuum tube circuit design. The self-customized AVM T83 S vacuum tube operates with balanced amplification. This patented vacuum tube technology reproduces the music vividly and vividly, and has a more excellent musicality. , Is a very new way.
The power supply of A5.2 also uses a more environmentally friendly switching power supply. Compared with the general traditional power supply, the switching power supply has the advantages of small size, light weight and high efficiency. Because if the traditional power supply transformer is to supply a large current, its volume is bound to be large, and large current will generate heat problems, so a large radiator is also required for power supply with a traditional power supply. In terms of efficiency, the efficiency of traditional power supplies is only about 30%, while the efficiency of switching power supplies can generally reach 80%. Of course, there are advantages and disadvantages. The disadvantage of switching power supplies for audio equipment is that the oscillation frequency of up to 100kHz will cause radio frequency interference, and radio frequency interference will radiate from the power line and enter the line itself through the DC transmission path. It is easy to cause excessive noise. However, many manufacturers nowadays have made effective shielding of radio frequency noise. On the one hand, they retain the advantages of high efficiency and small size of the switching power supply, and on the other hand, they have improved the shortcomings of radio frequency noise interference. Many Hi-End models now use environmentally friendly switching power supplies, and their sound quality has not been affected at all.
Why does the editor strongly recommend that AVM''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s CD3.2 and A5.2 be matched together? First of all, in terms of appearance, the two are a perfect match. The unified German style, coupled with the exquisite and flawless workmanship, when placed at home, will completely upgrade the layout. In terms of sound, because it is a product under the same brand, the direction of sound is also the same. The Evolution.2 combination not only reflects the many details of the record content, but also tightly grasps the real feeling in the music. It is smooth and not frizzy, and the overall performance does not appear jerky at all, crisp and crisp. Clean. Many German models often feel too bright in the middle and high frequency bands, but the Evolution.2 combination not only does not have this shortcoming, its sound has a high resolution and a warm charm, which sounds very impressive. Comfortable.
