Given the depth parameter, that is helpful.
Check out the Hegel H20. It is 37cm deep. Plenty of power and Hegel is known for a warm yet detailed and smooth sound. Ideal for B&W and no more expensive than the etude at this time.
Tonally, an NAD C298 would be better than the Chord etude. It is 390mm deep and recently received a Stereophile class A rating and for good reason. It is not the best amp I have ever heard, but it is the best $2K amp I have ever heard.
