I find the WAF ok but there's plenty of stuff out there that is better in that regard. IMHO.
I spent some time in the Zanden room at HE2004, I thought the speakers were the weakest link in that setup. I brought my favorite test disc along for the ride, and even the guy in the room wanted to take my disc off the system. It just couldn't handle low end bass at all. But anyway, thats a moot point for this thread.
I've been living with a Zanden MK3 for about a month now. For my ears, the Zanden is an experience that needs to be heard. I had a friend over to hear it, and his comments were that there was no trace of digital sound. The music definately has soul now, relaxed, dynamic, and full sounding. Detail is the best I've heard.
I'm still tweaking the setup, but I'm very pleased.
