I have a Wadia 6 bought in the mid-90s (220 volt) and never had any problems with it. I haven't found the need to upgrade (IMO, it still outperforms many CD players to date), except perhaps to the Wadia 9 itself. It's very well built, at a time when they were less commercial than today.
I listened to their PowerDAC (Wadia 790) once - it has an improved and "cleaner" sound than the 6, but you can definitely hear the same Wadia characteristics.
