Parasound CA2 or Sunfire signature 400 channel

Anyone can help me decide.. the speakers would be Sonus Faber Cremona...

Thanks for your kind attention & help
Sunfire by a nose. Allows you to bi-wire the front 3 channels, with current source going to mids and highs and voltage source going to the bass. Am on my 3rd set of speakers (now Legacy WHispers) doing this with great success. You can achieve a rich, almost tube-like sound with a powerful SS amp. What could be better?
