Reviews

"They're fast, beautifully integrated and have as seamless and cohesive a sound as you can find at this price level.

Listen to something like Tracy Chapman's Let It Rain and the CF4s sing. They pick up plenty of detail and deliver it in a forthright and direct manner. Their grasp of timing is good and overall clarity is impressive. 10/2004
