CS600 Integrate Amplifier

TWO SELECTIONS OF OUTPUT TUBES: 6L6GC(5881) AND OPTIONAL 6CA7(EL34) TUBES.

By switching two selectors inside of the cabinet, you can use either of 6L6GC or 6CA7 (EL34) , and LED indicators on the front panel will show you which tube is applied.

“PREAMP-IN” terminals on the rear panel allow you to use CS-600 as a power amplifier. 
By switching a selector on thr front panel, by-pass all the functions only excepting a Volume control.

A WIDE RANGE OF SPEAKER APPLICATION

Multi output impedance selector: 4/6/8/16 ohms.

A wide-ranged and flat frequency response upto 100KHz is enough capable for future digital audio format such as SACD/HDCD.

CS-600 FEATURES

  • Twin-triode tube 6CS7 for the first-stage amplification.
  • WBT type speaker terminals.
  • Heavy-duty output transformer for 50W grade amplifiers.
  • Large capacity choke-coil: 5H350mA
  • Dumper tube 6CJ3 (for Colour TV use) is applied to delay a supply of high voltage (B-Voltage) to output tubes in order to protect output tubes from damages and to longer the life.
  • All high-end audio grade electrical components (condensors, resistors)
  • Operation lamp indicator
  • Succeeding a front design of CS-300/CS-300X.
  • 24K Gold-Plated Knobs.
  • Side Wood-Panels.

RS30EQ Phono Preamplifier

RS-30EQ is equipped with the CR-type equalizer based on GE(General Electric/USA) 12AT7 authorized by J.A.N.(Joint Army & Navy) standard of the US Army, and can reproduce a very high quality and clear sound without adding any NFB.
To avoid compromising sound quality using the NFB type, one of the solutions we adapted to completely protect the sensitive CR type equalizer was to originally develop for RS-30EQ a high quality “Orient-Core” power transformer perfectly shielded to shut-down hum noise from the transformer perfectly.
We have also selected the finest available high-end audio components to keep the deflection of the RIAA curve below +/-0.2%.

CS300XS Integrate Amplifier

SMALL AND POWERFUL TUBE EL84 (MADE BY “SOVTEK” / RUSSIA)

CS-300X(S) is equipped with SOVTEK Tube EL-84 which has been welknown by audiophiles for its high sound quality against its small size.
A high input sensitivity of EL84 does not require a complicated circuit and accordingly, it can create a low distortion output signal.
