simaudio 605i 750 cd vs bryston

Hi, which way too go...sim 650i and 750 cd [how is the 650 cd] vs bryston 7bsst monos 26 pre bcd1?
too many unknowns here mainly the speakers you will be matching your gear up to...

While there is synergy within components don't pin yourself in a corner with having to acquire all the components from the same manufacturer (IMHO) although I will say a friend of mine has your proposed Bryston combo mated to a pair of PMC OB1i speakers and it all meshes very well.
