W-6 Mono Differential Power Amplifier
|
 
|
Also available with silver faceplate          
|
|  
|
This fully balanced differential mono-block amplifier produces 425 watts into 8 ohms, at least 650
watts into 4 ohms and is capable of driving virtually any loudspeaker. Employing our "Advanced
Renaissance" technology featuring a "no overall feedback" circuit and bipolar output devices, the
W-6 produces a warm, grain free sound common to some of the very best tube amplifiers, but
has the reliability of solid state designs. This amplifier possesses the same sonic signature
as the larger and more powerful W-10 but at a more affordable price. With respect to external
cosmetics, the W-6 is similar to the W-3, the main exception being the rear panel
connections.

Significant Design Features
A "no overall feedback" design resulting in real-time amplification, a more
accurate musical reproduction with respect to tonality, virtually non-existent intermodulation distortion
and the elimination of common phase errors resulting from feedback ·
An oversized power supply ·
A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss,
yielding an improved power transfer and lower regulation factor, resulting in increased current
speed and better dynamics ·
Fully balanced circuitry throughout the entire amplifier ·
Stable to any known speaker impedance ·
"Class A" output to 10 watts for greater efficiency ·
Precision matched Bipolar output devices which offer superb linearity throughout the entire audio
frequency spectrum ·
A high damping factor which yields superior musical dynamics, improved signal speed and refined
timbre accuracy ·
A very short signal path for a faster transient response ·
Accurate matching of the very finest high quality electronic components ·
Extremely rigid chassis construction to minimize the effects of external vibrations ·
A symmetrical circuit design ·
A 12 Volt trigger for remote operations ·
Pure copper circuit board tracings with extremely low impedance characteristics ·
Designed to be powered up at all times for optimal performance ·
Low operating temperature for a longer than normal life expectancy.
