Prima Luna 1/2 or 5 for Totem's Mite??

Hi guys,
I have a pair of Mites currently powered by Cambridge Audio 640A, it sounds good but not as good as I wish. The biggest problem is the treble seems forward too much that gives me a headache all the time. I've contacted Totem but their suggestions seems too expensive for me. I heard some good words about Prima Luna amps (I and II) but I can't find a dealer to demo them in Vancouver, B.C. So what will you think about this combination? Or there are any other suggestions? My budget is around C$2000.

My equipment are:
Rega Planet 2000 CD Player
Van Den Hul Integration Interconnect Cable
DH Labs Power+ power cord to Rega
Kimber 4PR speaker cable
D.I.Y Power cord to Cambridge 640A

Any inputs will be appreciated,

S.G.D
