Leben CS-600 Integrated Amp

The Leben CS-600 integrated amplifier is one reason why there is a Leben Audio Lovers' Club in Japan. Ideal for less sensitive speakers and those who want a little extra power, the CS-600 was developed at the insistence of customers. Leben is a name that speaks for itself and is widely acclaimed, with sales driven more by demand than by promotion. They are hand made and if you are looking for an integrated amplifier for your home as part of a great music system you'll need to look no further. It has a classic retro look and fits neatly into environments such as prestige apartments and homes and sits very well indeed with audiophiles.

If you have any doubts about the prestige of this product look no further than some reviews... Six Moons review, Jeff's Place review, Positive Feedback and Sonic Flare

The Leben CS-600 is a top-range integrated amplifier utilising the best components and workmanship. By switching two selectors inside of the cabinet, you can use either of 6L6GC or 6CA7/EL34 (not included) and LED indicators on the front panel will show you which tube setting is applied. Pre-amp In terminals on the rear panel allow you to use CS-600 as a power amplifier by switching a selector on the front panel, you can by-pass all the functions except the volume control. A wide-range and flat frequency response up to 100kHz is capable enough for digital audio formats such as high resolution streaming, SACD and HDCD.
