High resolution compatible terminal
In the case of the iPhone, it does not support the output of high-resolution sound sources.
Therefore, it is necessary to prepare a headphone amplifier equipped with a DAC that supports high resolution.
In the case of Android, there are terminals that support high resolution such as Xperia.
To enjoy high-resolution sound quality, you need to check whether the terminal that plays music is also compatible.

Let’s take a look at each feature.
Achieves smooth operation despite its compact size
Many people support the compactness of the ACTIVE “CT10”.
It’s smaller than most smartphones and fits in the palm of your hand, making it easy to carry.
And despite its small size, it uses a “quad-core CPU” for exceptional stability.
The “Quad Core CPU” has high processing power and offers smooth operation.
The processing power is important because it is high resolution, which usually has a large capacity.
Astell & Kern exclusive sound quality
ACTIVE “CT10” is a collection of Astell & Kern technical capabilities.
Astell & Kern is the original brand of IRIVER Korea and has developed many audio players compatible with Hi-Fi / Hi-Res sound sources.
Due to its high sound quality, it is now one of the standard brands of high-resolution players.
ACTIVE “CT10” boasts of sound quality because it requested development support from the IRIVER group company.
Up to 400GB expansion with MicroSD card
Since the capacity is 16GB, it is a little small to put a high resolution sound source.
However, since it supports MicroSD cards up to 400GB, it can be expanded up to 416GB in total.
It is sold separately, but if you want to put a lot of music on it, buy a MicroSD card.
High resolution has a large capacity.
groovers will end on June 30, 2019
ACTIVE “CT10” was able to buy a high resolution sound source directly from the player body.
However, it cannot be used now because the distribution site “groovers” has ended.
However, ACTIVE “CT10” can easily transfer music from your computer.
Just because “groovers” have finished doesn’t mean you can’t listen in high resolution.
Difference between analog data and digital data
Analog is a line.
Digital is a point.
Digital data can be brought closer to analog (line) by arranging points in succession.
The record is analog because it records continuous sound waves in the groove as is.
A CD divides continuous sound waves at regular intervals (sampling) and applies numerical values to each division (quantization).
Then the flow consists of converting the numerical value into digital data suitable for a computer (encoding).
In this way, digital data is only one point, so in theory it is further from the original sound than analog.
However, since it is indistinguishable to the human ear, it is possible to enjoy the sound digitally without any discomfort.
