It would depend on various factors: What kind of music you like. How
large your listening room is. What speakers you will be using. etc.

Classical music - not excessively loudly but of course orchestral
climaxes can be loud. Digital sources - not vinyl. Room 11' x 13' x 8'
high (rather small probably for the speakers Focal JMLab Chorus 714V
Power handling 130W max (90W nom) Sensitivity 91dB)

An orchestra even in the auditorium can peak at over 120dB.

To recreate that with 90 odd dB sensitivity speakers requires a 1kW / ch
amp.

Probably true if you listen outdoors. :-)

That's why decent studios have such things. Probably about 6 of
them for 5.1 sound.

Do studios routinely use speakers with a 90dB sensitivity? Afraid I don't
know much about that area, but assumed they used speakers of types that
would be less sensitive. Also that their room acoustics and normal levels
different to most domestic replay.

Slainte,
