I did not care for the W4S amp that I owned, although if you can demo a Bel Canto amp, you will get a very good sense of whether you would like W4S or not, as I think the Bel Canto Class D amps sound very similar to the W4S amps.
Personally, I would take a good class A/B amp (Classe, Pass Labs, Modwright) over a class D, but everyone has different tastes.
