The Krell 600, 600c or 700cx can be used successfully with a RCA output preamplifer - some people even prefer this mode to the XLR or CAST mode. Input impedance of MCX models is 100 kohms that can match almost all known preamplifiers.
Tube preamplifiers known for having DC offset or DC leakage should be used with the internal coupling capacitors engaged.
"A one piece RCA-to-XLR adapter is available
from Krell Industries, to allow single-ended operation
using the balanced XLR inputs" - taken from the Krell MCX manual.
