The big difference between analog and digital is that analog allows signals that digital often rejects. A high frequency and high resolution digital can be perfection, but the typical CD/MP3 type of digital is too low of a sampling and too low of a resolution, meaning the bits that describe an instance in time are too low to allow the analog harmonics to come through. So, most corporate boom-boom garbage is fine at digital rates, but finer music of great string playing won’t come through in digital unless sampled at a higher frequency and at a higher resolution.
From a recording perspective digital is very convenient because the recording stations are very compact. From an instrument amplification perspective digital can be used anywhere that you won’t clip or distort the amp. Analog or tube distortion is a beautiful rich warm fuzz. Digital distortion sounds like a cheap ass effects box.IMHO.
