One of the infrastructures: air blade.

Since his requirement is to see the picture, and it is a three-dimensional stage full of energy, the treble needs to be diffused 180 degrees, but there must be no roll off at the same time. This technology cannot be achieved by putting multiple diamond tweeters together, because their dispersion angles are extremely narrow. It is quite knowledgeable to combine the air blade with the main body horn. I had many field discussions with him to decide the location of the air blade. He has great listening skills and has objective principles, so he gets things done quickly. From now on, listening cannot be done without the air blade.

Infrastructure 2: JMF Audio PCD10235th Anniversary Luxury version.

Power processor products are like stars, so the conditions for his selection are very strict. Due to his professional background, he chose French JMFAudio. The reason is that over the years, many recordings using JMF Audio's PCD102 have been nominated for the "American Grammy Music Awards", and in the end, the LUX recorded by Norway's 2L did win the 60th Grammy's Award - Best Recording in 2020 Awards. Aaron believes in the guidance of musicians, and he also believes in the authority of Grammy because he is also a musician. Many deans of the Hong Kong Academy for Performing Arts also agreed that JMF Audio PCD102 is an epoch-making instrument.

Infrastructure three: Tripoint Troy SignatureNext Generation (NG).

On the same day, after I gave a three-minute demonstration of Tripoint AudioTroy Signature NG at AE Central Studio 2, he immediately understood that it was a necessary audio infrastructure. He described, "When the system is not connected to NG, the picture disappears and the atmosphere disappears immediately." Later, after I installed the entire system at his house (everything was brand new without any warm up), he listened for ten minutes and said: I said, "Why can't I see Lady Ga Ga wearing lipstick? I saw it clearly in your store. Chris, I couldn't receive the goods." I was very panicked at that time, and then I checked all the wires. Once, it was finally discovered that the cable of the Troy Signature NG was not plugged into the wall. After the problem was solved, he immediately listened again. About a minute later, he smiled and said to the whole crew: "I see she is wearing lipstick now. I am shocked." It's not a problem with the warm up. Don't worry, I'll take delivery of it! I'll replace it with a stronger cable later. It's impossible to listen to this Troy Signature. NG has been out of stock for many years. Especially after a closed-door ABAB comparison, several senior people personally verified that it is completely different from the previous generation flagship Troy Elite (the black gold wooden box is already super strong, and I have used two of them so far). , which stimulated huge demand.

When Aaron and I were co-writing "Guo Ba Tiao", he once said: "Chris, I think music should be integrated. On the contrary, the separation between instruments is A three-dimensional sound effect concept. I understand that the three-dimensional image is very sensory. But on the real stage, dozens of people sing and dance together, and the audience in the audience hears the overall musical feeling, not the ear-test performance. The separation distance between them, and calculating how many people are performing at the same time. I regard the sound system as a medium to enjoy music, so the accuracy of the beat, the coherence of the melody, and whether the energy transfer is sufficient are all important to me. Before I met you, I thought audio was mainly about pursuing three-dimensional sound effects.

But you proved to me that the picture can be heard as real as it is, and the overall integration is as if I was at the scene. ”

After Aaron experienced the performance of Mahler’s Ninth Symphony in the Divine Comedy Studio, he believed that Goebel’s Divine Comedy playback symphony was like a seamless canopy, and the communication between the various instrument groups was very clear and mutual. It expresses Mahler's experience of life and death. The super giant trumpet completely disappears into the physical space, and the musical energy of different sizes passes through his body, creating a sense of music. He describes the sense of music as derived from the whole.

Since he was waiting for "Divin Nobleness" for four months, he listened to "Divin Marquis" at home, so his integration with Goebel's Divine Comedy series. Nature, integrity, energy, and picture composition ability, etc., are already well understood. Marquis has become an important speaker interface that gave birth to Guo Badiao.

Guo Tianhuang does not have any experience in audio fever, so he has no preference for any brand. His subjectivity only comes from his preferences in music categories. Why did he choose the Chinese Divine Comedy? From the technical analysis, we have the following conclusions: (The following data are taken from Goebel's official website.)

Divin Majestic 98db; lowestimpedance 3.3 ohm at 100hz; 21hzto 24,000hz

Divin Nobleness 95db ; lowestimpedance 3.8 ohm at 100hz ; 21hz to 24,000hz

Divin Marquis 92db; lowestimpedance 3.4 ohm at 95hz; 21hz to 28,000hz (-3db)

First of all, they are all three-way design, that is, there are only two crossover points. The most obvious difference is the sensitivity. The Major Divine Comedy is 3db more than the Medium Divine Comedy, and the Medium Divine Comedy is 3db more than the Minor Divine Comedy. The frequency response of the eldest brother and the second brother are exactly the same, but the third brother has a higher extension because its AMT tweeter is thinner. The thinner the tweeter, the higher the extension, but at the cost of reduced sensitivity.

According to my experience, the most important function is the "minimum resistance expansion value", because it determines the relationship between the speaker and the power amplifier. The higher the value, the lower the burden on the power amplifier. This value is constantly changing during music playback, sometimes high and sometimes low. The smoother the resistance expansion curve, the easier the speaker is to be driven and controlled.

In the entire series, the lowest resistance expansion value of the Chinese Divine Comedy is the highest -3.8Ω, which is 15.2 higher than the Great Divine Comedy. This means that the Chinese Divine Comedy is easier to push and control at 100hz. Since this is the bass band, the energy must be freely retractable and retractable in order to convey the sense of music, which is exactly one of Aaron's requirements. Therefore, the matching of Zhongshenqu and power amplifier is more flexible.

Today, Oliver Goebel finally completed his Divin Nobleness. I look forward to it bringing an infinite musical experience to Aaron and deepening the mystery of Guo Badiao.
