 (Note that vinyl records may be mastered differently from their digital versions. ) In the amplification stage The 44.1 kHz sampling rate of the CD format, in theory, restricts CD information losses to above the theoretical upper-frequency limit of human hearing – 20 kHz, see Nyquist limit. Nonetheless, newer formats such as FLAC, ALAC, DVD-Audio and Super Audio Compact Disc (SACD) have sampling rates of 88.2 kHz, 96 kHz or even 192 kHz. , vacuum-tube electronics remain popular, despite most other applications having since abandoned tubesfor solid state amplifiers.
