If you haven't gotten your amp yet, I would suggest you listen to Steve McCormack's DNA-500. That's what I'm using on my WHispers and the sound is amazing. Lots of power and current (500w -8 ohms/900w-4 ohms),very musical, loads of detail without being fatiguing and very "involving" - it draws you in to the music. Tight bass control is also another characteristic.
In fact, even if you HAVE already gotten your amp, if its not the DNA-500, you might want to audition it anyhow just to see what you are missing!
