Dared Tube preamp/amp??

I just now learned about Dared tube equipment. The price definately seems right, but I know nothing about them. Has anyone used these? If I get the SET tube amp to go with the preamp, what speakers are good to use? Will they run Wharfedale Diamond 8.3? I am looking for a relatively low budget system, but with good sound quality. Also considering Jolida integrated amps (to give you an idea of what I'm looking at).

Thanks
