    Amplifiers are used to drive loudspeakers. Most of the time, the engineers use headphones when they are processing the music, instead of playing the music through loudspeakers. Class A amplifiers are generally preferred by audiophiles but they are expensive and they are high wattage and they can get hot. Therefore they probably use class B amps when they have to listen to music through loudspeaker.

    Any that suits the circuit designer(s).

    There is no standard.

    Depending on what instrument is being recorded, it may just be connected directly to the recording system without any amp.

    For some instruments, a microphone is used (or several mics), such as for acoustic drums, an organ with a leslie speaker, a grand piano or a guitarist who wants a specific tone generated by their amp. 

    A lot of recent music is generated digitally and recorded via a computer.

    The only amps almost guaranteed to be used at some time are for monitoring or reviewing the recording / mix as work progresses.

    A lot of the time, the musicians or vocalists just listen on headphones rather than using amps.

    It depends very much on who is doing what and how they prefer to work!

    Edit - seeing another of your questions, you meant the functional class of power amps - A, AB, D or whatever?

    All normal analog low-level signal processing is normally Class A in any type of audio gear; preamps etc.

    Where power amps are used, they would almost certainly be Class AB; that is by far the commonest in non-digital gear.

    Some more recent PA equipment may be Class D, but that's not likely to be in use in existing studios - it's generally used where power efficiency is more important than absolute quality.

      A lot of stuff targeting "audiophiles" is is based on meaningless buzzwords, purely to sell pointless gadgets & accessories for ludicrous amounts of money, when in fact the stuff is no better that a lot of good mass-market gear at a fraction the cost.
      Sometimes the "audiophile" stuff is not as good.
