Some audiophiles use, rather than a stereo power amplifier, two monaural amps, one per channel, in "monoblock" configuration. Some go further and use multiple amplifiers per speaker to drive the woofer, midrange, tweeter, and so on. However, there are those who claim advantages in the use of "integrated amplifiers" that combine these functions in a single box, arguing on the basis of an appeal to minimalism.
Next studio speakers will be seperate amps for low and high (sub going in later) as well as their monoblocks
On the other hand, there are others who use solid-state amplifiers rated at over 1000 watts RMS" per channel.
DJ's, yes. Audiophiles that I have seen dont use that powerful of stuff.
And personally my pet peeve is Digital to Analog conversions and vice versa, it's one or the other and no conversions
If im using a digital amp, I want optical out on cd player, fully digital mixer and digital in's on the amp.
