It's all about the listening experience.

• Warm-up: The main purpose of warming up the audio is to keep the DAC activated, so you can turn the volume to the maximum. You can warm up the audio for 10-30 minutes before using it every time. After warming up, you will find that the sound will be more flexible and smoother.

• Run-in refers to the continuous use of the audio system for a long period of time to age the speaker drivers, so it won’t make stiff and sharp sound, and make the sound mellow and sweet to the maximum. (Usually the speaker cone of the new driver and overhangs are tighter, and the sound is relatively tight, so the sound field is not wide enough and the sound image localization ability is slightly worse, either.) Many audio lovers liken “run-in” to driving a new car so that all parts can run in for a period of time to achieve the best working condition.

As far as our small CUBE system is concerned, the volume can be adjusted according to your actual situation. In principle, the sound should be as large as possible, and the music to be played must contain high, medium and low frequency.

Since the advent of the CD, the sampling rate of digital audio sources has remained at 160bit / 44.1kHz for quite some time. However, a large number of high-resolution music above 24bit / ß96kHz has been released recently, and the sampling rate is three times that of CD. It is commonly referred to as high-resolution sound source. 

Why is there a high-resolution audio source with a sampling rate exceeding CD and up to 96kHz?

First of all, it is difficult for the human ear to hear pitches as high as 20 kHz. However, if the overtones are generated with a pitch of 300 Hz (low frequency), even if it is as high as 20 kHz (high frequency), the human ear can easily recognize it.

Secondly, because humans do not discern ultrasonic waves like bats, they cannot identify pitches with frequencies as high as 40 kHz. However, if the overtones are generated with a pitch as high as a frequency of 40 kHz, the human ear can feel it even if it cannot recognize it.

The selling point of high-resolution audio source products is to record the ultra-high-frequency overtones that the human ear can't recognize, but can feel it in the audio source, so as to improve the quality of music.

At present, the audio source quality of online music streaming software such as KK BOX, Spotify, Apple Music, etc. are all 160bit / 44.1kHz similar to CD. If you would like a better audio source, Qobuz, Tidal and other lossless audio streaming software are some good options.

In 1919, the American physicist Arthur G. Webster invented the exponential type corner horn. Due to the efficiency as high as 50% (the efficiency of the general moving coil horn is only 1-10%, the efficiency of the Klipsch horn horn is about 30%). Soon it was widely used in theaters, stadiums and other places that require loud sound. read more...

Sarah McLachlan is well-known for singing the movie "X Lover" episode "Angel", and let the world know her with a clear and sweet sub-soprano; the success of this Canadian creative talent is not accidental.

Classic: Sarah McLachlan 〈Angel〉
"In the arms of the angel..." Through Sarah's perfect interpretation, the clean and ethereal voice filled "Angel" with a light but strong sadness.

All the narration through songs is so natural that people can't help but feel compassion; but Sarah hopes to awaken addicts with singing. Such forgetting is short-lived. , There must be sorrow in life, learning to embrace sorrow can truly escape the pain.

It is more well-known, but it is not a movie volume. The songs created by the body can warm the sad heart with the same melody.

Pink Floyd started out in London, UK. Formed over five decades ago, the band is known for its experimental and conceptual style. Then taking the music industry by storm with its 250 million records sales across the globe, Pink Floyd has a status on a par with The Beatles, for the rock and roll music fans.

In the early days of the music industry, Pink Floyd started with psychedelic rock and roll music and later received international acclaim with their progressive music. Pink Floyd portrayed the social conditions at the time and presented the dark side of the society with music to provide catharsis. Pink Floyd brought on a perfect fusion of music and life, thus becoming an epochal canon in popular music.

Along the way, the band went through turbulence, break-ups and make-ups. In their later years, the band members focused on releasing solo albums. Nevertheless, Pink Floyd has made a solid benchmark in the history of popular music and repeatedly shaken and energized the music industry.

“Wish You Were Here”

Pink Floyd created the album, “Wish You Were Here”, in tribute to Syd Barrett, who at one point led Pink Floyd from an underground band to the mainstream, but left the band due to drug addiction. It was Syd who brought the band in its early phase to psychedelic infusion.

Its previous album, “Dark Side of the Moon”, achieved much commercial and artistic success and subsequently gave the band members a taste of fame. The long-standing creative tension between David Gilmour and Roger Waters started to grow about that time. So in the beginning of the album production, band members were all half-hearted about it, lacking mutual understanding and communication. Then Syd Barrett as a member that had left the band paid a surprise visit which turned the band around, and as a result, the album was saturated with reminiscing sentiments for Syd Barrett.

The eponymous song, “Wish You Were Here”, has a ballad-like melody coupled with elegant yet easy-to-comprehend lyrics, carrying a touch of sorrow and reminiscence. Embedded in the song are memories, questions and epiphanies on life, leaving one overwhelmed and filled with emotions.
