About the DUO 300 XD
The Krell DUO 300 XD is a reference-grade stereo power amplifier combining Krell's proprietary iBias Class A operation with XD (Xtended Dynamics) technology. Designed for audiophiles demanding uncompromising performance, it delivers 300W RMS at 8Ω (540W at 4Ω) with exceptional low-impedance stability. The XD upgrade reduces output impedance for improved driver control and transient response, while iBias maintains true Class A operation without excessive heat generation.
