The CS-300X has five inputs, a tape monitor and a headphone output. It delivers 15 watts via a quartet of NOS Mullard EL84 pentodes configured for push-pull operation. The driver stage consists of 2 x NOS G 5751 dual triodes which are DC coupled to eliminate noise. The loudspeaker output also drives the headphone port - cans and speakers receive identical signals. The CS-300X has a unique bass boost control that operates via a simple cap/resistor circuit on the negative feedback loop as opposed to a separate, more complex circuit as commonly used. A 15-kOhm resistor prevents any undue sonic influence of this control on the midrange. The little "Life" is self- biasing via a cathode resistor which supposedly reduces noise and precludes any periodic fiddling with a multi meter and screwdriver. Just plug it in and let the good times roll. Various audiophile goodies litter the innards of the Leben, including metalized polypropylene caps with mesh-shielding, caps from Sanyo and Elna, "RMG-F type" resistors with gold-plated leads and custom transformers.
