Krell Chorus 5200 XD (5200XD) 5 Channel Power Amplifier
CHORUS 5200 XD 5 Channel Power Amplifier
200 Watt Amplifier Featuring Krell iBias Technology

Krell's New XD Technology
Krell’s “XD” (Xtended Dynamics, Xtended Dimensionality, Xtended Detail) upgrade for the iBias amplifiers takes analready great sounding amplifier and raises its performance to the next level. “XD” is a classic example of Krell’s continuous R & D efforts reaping benefits across multiple product lines. During the development of the K-300i Integrated Amplifier they discovered substantial sonic improvements by lowering the output impedance below traditional norms. So they applied this technique to their existing line of amplifiers and the improvement was so substantial that it required a unique designation, hence, “XD.”

It was no simple matter to just lower the output impedance. This affects the amplifier’s stability and transient response so each stage prior to the output stage had to be re-tuned to work optimally with the lower output impedance. This lower output impedance exerts more control over the speaker drivers and damps out unwanted vibrational modes, allowing a more accurate reproduction of the original signal.
