I think the target market is people who don't need a lot of power, but want very clean amplification.
Not everyone needs a lot of power. For example, take a 4 ohm speaker with 86dB/1W sensitivity. This amplifier will drive it to over 104 dB. Assume that the listener listens at 80 dB. There still is 24 dB of available headroom. Moreover, many speakers encounter high distortion and compression above 100 dB, and probably should not be pushed that hard anyway.
As an example, my first home audio amplifier was a Rotel 20W/channel integrated amplifier. I used it with SpeakerCraft No. 4 speakers. I don't recall their sensitivity, but it probably was somewhere around 89 dB or so. That system played plenty loud for me, without distortion, even in a very open room.
