Dusty is correct: the 25-watt KR Audio "Kronzilla" didn't have enough power to play loudly on crescendos. However, the CIA D200 Mk2's powered our new VR-100XS to a level of bass performance that had to be heard to be believed! Please visit the Von Schweikert Circle to see photos of the complete system; you'll see the CIA D200 Mk 2's sitting next to the Kronzilla on expensive rack stands by Critical Mass Systems. By now, most of you also know that Dusty builds the amplifier plates for the XS subwoofers used in the VR-9, VR-100, and VR-11 systems by Von Schweikert Audio. We could have used any number of brands of amplifiers to power our systems, but we chose CIAudio based on reliability, sound, and great customer service.
Happy Listening,
Albert Von Schweikert
