integrated amp for totem dreamcatcher monitors

I just purchased a new set of totem dreamcatcher monitors with a small sub, i had been considering arro and rainmaker alone but this particular monitor sub combination sounded great, i am still waiting for arrival and will have to see how it sounds at home, but i was hoping for some suggestions for an integrated that might work well with these little speakers, i am considering some cheaper integrated ss stuff such as NAD C320bee, or C352, or Cambridge audio 640a. additionally i am considering more expensive ss stuff used like musical fidelity x-150, music hall mambo, or maybe cheaper used tube amp like jolida 40 watt. Despite their small size the Dreamcatchers are very power hungary, they are 4 ohm and not very sensitive, in fact totem reccommends more power for these than for the arros or rainmakers. All commentary over mentioned amps as well as non-mentioned amps is welcome.
Thank you very much
