could someone compare krell vs. classe audio ?

Krell and Classe are both high quality manufacturers but have distinctly different sounds.

People who like forceful dramatic bass and a more in your face presentation are Krell fans.

The Classe house sound is smooth in nature and does also have a oomph in bass though not as much.

Note that I am an owner of an all Classe stereo so I am more biased to the Classe sound.
