Proabably the best sounding 300B amp, sans
the Napoleon. The X2 uses the new 6C45PI input/driver tube that
is very similar to the WE437A. This tube is capacitor coupled
to the 300B in choke input configuration. This style used also
in the Gemini allows the X2 to be very dynamic and have a higher
power rating than the rest of the Cardinals. Simply my first choice
in the Cardinal line!
The Cardinal is a monoblock amplifier featuring an RCA input jack,
Cardas 5-way binding posts, an on/off switch and a detachable
IEC power cord. The amplifier base is available in solid cherry,
curly maple or walnut. Other woods are available, some wait required
for custom types.
The Cardinal received The Best Component of 1994 award from the
absolute sound in issue #100; in addition, it was very favorably
reviewed by Jonathan Valin in issue #99 of TAS.
Like all Wavelength Audio products, the Cardinal is a handmade,
limited-edition instrument based on unique vacuum tube designs.

Cardinal WE The WE version of the Cardinal is based on the same circuit as the original XS version. The WE uses the same transformers but uses the WE420A/5755 (6SL7 tube in a 9 pin configuration). The WE also uses the WE274 rectifier instead of the 5AR4. This model is for people that want to experience the complete WE sound. |
|
Cardinal XS The power supply of the Cardinal uses the renowned 5AR4 rectifier in conjunction with a pi filter using only high-quality film capacitors. The voltage amplifier stage uses a select 6SL7 in SRPP configuration coupled to the 300B in self-biased mode, for a clean 10W output. The simple circuit is engineered to exacting specifications and realized with carefully-selected premium parts throughout. |
