For those who need more power, Leben introduces the new CS600 integrated amplifier with a choice of 28 or 32 watts of wonderful tube power, depending on which tubes are used. Through a selector switch, one can use either 6L6GC for 32 watts, or 6CA7 (EL34) for 28 watts, with LED indicators to show which are used.

A full function integrated amplifier, and it can even be used as a power amplifier through a preamp-in terminal.

Retro look reminiscent of older McIntosh and Luxman equipment, but with a wide-range and flat frequency response up to 100Khz, ready for future digital audio formats.

TWO SELECTIONS OF OUTPUT TUBES: 6L6GC (5881) AND OPTIONAL 6CA7 (EL34) TUBES
By switching two selectors inside the cabinet, one can use either 6L6GC or 6CA7 (EL34) tubes, and LED lights on the front panel will indicate which tubes are applied.

POWER AMPLIFIER DIRECT SWITCH & INPUTS
"PREAMP-IN" terminals on the rear panel allow you to use CS-600 as a power amplifier.
By switching a selector on the front panel, one can bypass all the functions except the volume control.

A WIDE RANGE OF SPEAKER APPLICATION
Multi output impedance selector: 4/6/8/16 ohms.

FLAT AND WIDE FREQUENCY RESPONSE
A wide-ranged and flat frequency response up to 100KHz prepares the amplifier for future digital audio formats and current ones like SACD.
