Parasound JC 1 or Musical Fidelity KW 550?

My experience with JC 1 in my system they did not bring the
music to life, compare to the Viva 300B tube amp with the
550K connected.If you will use the right pc with the 550k
they are hard to beat,I use dcca and cpc model 11.I also believe the the Thiel speakers will match the JC1.Dont get
me wrong the JC 1 are good,but not in my system.
