Amps for Dynaudio Confidence 5s?


I am putting together a 2-channel system starting w/ the Confidence 5s. Deciding which amp (and preamp) to buy. Currently looking @ Classe CA-301/CP47.5 and Bryston 7BSTs/BP-25. Comments, suggestions and personal experiences ( about the components) appreciated

My thanks to everyone for your thoughts. Krell too expensive. McCormack not available. The winner is... Classe CP-60 preamp and CA-401 amp.Was going to go w/ another preamp ( non-Classe') until I heard the 60. Sounds much better than 47.5 and 50 I had heard ( maybe due to remote power supply)combo sounds excellent. Thanks again for your input.
Go with an all Krell set up and you should reach nirvana.The amp has to be a KSA 300S or a FPB 300,or better yet a FPB 600.A KRC-HR pre as well.I take it,if you spent $10 K for the Confidence 5 speakers,why save on your front end(your heart).Go for it,I did.All I can say is the Confidence 5's are amazing,they just need mass to open them up.(P.S.the new Pass labs will also satisfy-X350,or better)
I own a pair of Confidence 5s and I am driving them with a Goldmund Mimesis 29 amp (about 300 Goldmund Watts!) but they need more power... The combo is simply wonderful but I would like more dinamic, then I have a big dilema. Krell 650 or similar could be a solution but Krell is too coarse in comparison with Goldmund. Perhaps with Dynaudio Arbiter...($270.000 ops).
