Best Amp/Preamp/CD or DAC for Wilson Watt Puppy 7

everyone always hears about the trickiness of matching great components together and was wondering what has made people happiest in conjunction with using the Wilson Watt Puppy 7 speakers.

I currently use the Wilson Puppy 7 with Rowland 302, BAT Vk51SE and Cary 306-200.

I have heard a lot about wilson puppy 7 with halcro and also curious about EMM dcc2 users with wilson watt puppy.

Thanks

Michael
