Concert Fidelity CF-i300B Integrated Amplifier
The CF-i300B is an all-tube integrated amplifier featuring a pair of the 300B output tube driven by a pair of 6SJ7/6SJ7GT/5693. Rectification is handled by a 5AR4/GZ34. The directly heated triode amp outputs 9 watts/8ohm per channel. The circuit topology is extremely simple and signal paths are short.
The CF-i300B has four sets of single-ended inputs and one of them can be switched
to balanced (XLR). Users can select the speaker output impedance between 4 ohm and 8 ohm. As a bonus, it has a solid-state headphone amp which can drive either pair of a single-ended or balanced headphones.
Inputs: INPUT 1-3 Line Level Inputs (RCA), INPUT 4 Line Level Input (RCA, XLR swithed)
Input Impedance: 100kohm (RCA single-ended), 50Kohm (XLR balanced)
Speaker Outputs: 0-4ohm-8ohm
Headphone Outputs: SE(1/4″ TRS) or BAL(XLR-4P)
