King. Combining the musical refinement of a Class A vacuum tube input stage with the tremendous power and control of a high-bias MOSFET output stage, the BHK Signature 300 delivers exceptional transparency, dynamic authority, and effortless musical reproduction.\u003c\/p\u003e\n\u003cp\u003eThis matching pair provides 300 watts per channel into 8 ohms and 600 watts per channel into 4 ohms, delivering the power and control necessary to drive demanding loudspeakers with remarkable precision. Each amplifier features a fully balanced differential architecture, dual 6922 vacuum tube input stage, and N-channel MOSFET output section. The dedicated monoblock configuration provides independent amplification for each channel, helping maintain excellent stereo separation, dynamic range, and soundstage presentation.\u003c\/p\u003e\n\u003cp\u003eFinished in classic black, \u003cstrong\u003eboth amplifiers are in mint pre-owned condition\u003c\/strong\u003e, presenting exceptionally well with virtually no signs of previous use.
