Swiss darTZeel Dasheng CTH-8550 combined power amplifier new licensed warranty
Every machine is a signed version
After you buy the CTH-8550, you cannot use it immediately, otherwise it will automatically stop after 15 minutes. You first need to insert a 2G USB flash drive that you carry with you into the USB port on the back of the machine, where all the information about your purchase is recorded. After sending the information to the amplifier, it can be used normally. This U disk is the key of CTH-8550, a “key” corresponds to each machine, and it can also be used for future upgrades. You can also register online and the factory will give you a special title. After you enter it, the screen will display darTZeel''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s trademark, body number and your honorific name in turn. Interesting! So every CTH-8550 is a signed version, and there is also your own “signature”.

The sound is as thick and warm as a direct heating transistor

What does the CTH of this CTH-8550 combined machine mean? Means Close to Heaven(Like heaven). If you abstractly summarize the sound performance of CTH-8550, just like the meaning of the abbreviation before its model, it can be described as listening to the darTZeel amplifier and enjoying the beauty of the sound of nature, no matter what you listen to.music, No matter how long you listen, you will never get bored and tired.
Specifically, the CTH-8550 is the transistor machine with the most tube sound in history. Its sound is very similar to the 211/845 tube, warm, thick and sound. At that time, there was Melody''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s Aodixun AN211 tube machine in our audition room. In contrast, the CTH-8550 not only has a strong tube flavor, but also has better analytical power, transparency, density and speed. We usually think that high-end models, whether it is a transistor machine or a tube machine, have both timbre and dynamics, but there are very few transistor machines like CTH-8550 that are comparable to the direct-heated triode in terms of sound. Listening to the Chopin Nocturne played by Rubinstein, you can feel the mellow and transparent piano sound and the flashing overtones lingering in the space. It has a warm color, cordial and natural. However, CTH-8550 is even better in that it has a wider sound field, higher analytical power, faster response speed, clearer and more realistic performance of piano vibration details and sound texture, and a wider dynamic range. As a transistor machine, CTH-8550''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s strength and analytical power are not bad at all. Compared with the tube machine, its tone and air feel are not inferior. I dare say that even in the case of blind listening compared with high-quality tube machines, if it were not for the higher analytical power of the CTH-8550, you might not be able to accurately determine which one is a transistor machine and which one is a tube machine. This is the greatest feature of CTH-8550.
Continuous internal force
In addition to the sweet sound, the CTH-8550 is a 220W output power amplifier, and its power is self-evident, at least more than 100W Mark Levinson No383. However, CTH-8550 does not have that rigid lethality, but a continuous internal force to support it. In other words, CTH-8550 is practicing Neijiaquan, with sufficient motivation but no sense of oppression. I think this feature is welcomed by most players, and only large-scale works have such a work. Although CTH-8550 has no rigid lethality, but due to its excellent analytical power and response speed, each frequency band has a good sense of layering in large dynamics, the sound field is very open, and there is a good sense of depth. Listening to the percussion clips in "Dragon Rhyme", the texture of the drums is excellent, whether it is the depth of the low frequency, the air of the mid-to-high frequency, or the touch of the drum head, it is vivid and lifelike. Its sound is not procrastinating at all. When playing the grand scene of Saint-Saens’ "Organ Symphony", CTH-8550 always maintains infinite stamina, and maintains an infinite sense of tension and dynamism. In short, CTH-8550 is a more connotative amplifier. Under the beauty and warmth, there is an inner passion that is exciting and inspiring, which is irresistible.
Speaking of this, you already have a general understanding of the features of CTH-8550, and those feelings that are difficult to express in words are for you to listen to and experience in person! This amplifier is expensive, 200,000 yuan is not affordable for ordinary people, but you are worth listening to, he will tell you how beautiful the sound of today''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s transistor amplifiers can be, whether only electronic tubes can emit heavenly sound. In short, CTH-8550 is a poetic amplifier, like Chopin in the piano, Saint-Saens in the violin, and Schubert in the singing. The beautiful sound gives you unlimited imagination and aftertaste.
