Hi
Well this is my first post but I have been surfing here for a while.
I bought one after listening to one after seeing the HiFi world review a few months ago. I spoke to a few dealers who also loves it..
Does it make a difference....BIG YES. It really is an eye opener. At present I'm using an Audio Aero Prima CD player and the DAP.10u has elevated it past the Audio Aero Capitol which costs 3.5 times as much. More detail, better low frequency and images to die for. I ended up selling my used Transparent interconnects to get one. The Whest just works straight out the box, and better than any interconnect I've had in my system.
Would I recommend it...YES! Just listen to one.
Apparently there is a HiFi News review out next month which again is supposed to be excellent.
good luck
