About  High-Resolution Audio format files
High-Resolution  Audio, which is  typically 96 kHz/24 bit or higher, is  made  by digitally sampling  an original  analog  audio
source. The  number of times at which sampling  is  performed (in one-second  increments)  is  called the sampling
frequency, which is  expressed in hertz  or “Hz.” Digitizing refers to the audio  process  where  the sampled signal is
converted (or  quantized) into binary  digits, consisting  of 1’s...

About  the balanced connection
Unbalanced connections have commonly been  used for portable audio  devices. This connection method works as L+/R+
signals go through an amplifier and L-/R- signals go through the ground. Devices with unbalanced output are  normally
less expensive  and easy to handle  compared  with the balanced output devices, but unbalanced connections cannot
prevent noise occurrence  since noise can be picked up if there is  a difference in voltage...
