Creek 4330, 5250 or 5350se?

Hi Folks,

as many people are doing, I'm trying to build a mid/hi fi 2 channel system on a budget. I really like the sound of B&W speakers and I'm thinking about the new 68 series or possibly used CDM, CM or even the older 805 Matrix speakers. Obviously, Rotel is in the running, but several folks have recommended Creek Audio as well. It seems that 5350SE is the current best Creek amp. The 4330 and 5250 are less expensive used. Does the 5250 sound as good as the 5350, but just not as powerful? It falls in my budget range. Also, would you rate the 5250 integrated over preowned Rotel separates?
