The RPA-W3EX offers a high speed basic platform that delivers well-defined clarity, together with volume and energy in the mid- and low registers, for improved musicality, and controls woofer damping, for a lively, powerful bottom end. This is an amplifier that will let you feel the shocking impact of “the Firebird” or the throbbing bass and pulsing bass drum of a jazz trio.

The side panels have evolved even further, and feature insulators with a hybrid configuration that sandwich maple between spruce board. The weight of the body flows down the lines of front face and the underside, where it is conveyed to the contact surface. It is constructed of spruce, which is also used in the tops of stringed instruments (German Spruce), and has excellent musical properties. Maple possesses just the right amount of rigidity, and is also used on the backs of stringed instruments. The new hybrid panels combine these woods, with 15 mm sides and a 45 mm contact surface, and make effective use of resonance and controlled vibration to achieve a rich reverberation that is very similar to that of a musical instrument. To provide three-point support, the rear insulator features the same hybrid structure as the side panels. The large hybrid block supports the amplifier chassis with perfect vibration characteristics.

We have offered a new concept for preamplifiers and power amplifiers.
In the past, conventional systems used a preamplifier to adjust the volume of the signal from the source before feeding it to a power amplifier. Because power amplifiers possess high levels of gain, for normal listening tests the input level to the power amplifier must reduced significantly. However, this increases the likelihood of losing some of the nuances in the signal.
To deal with this, SPEC power amplifiers feature an analog electronic attenuator immediately ahead of the power stage able to take high signal levels from source devices 
and able to adjust the volume by the external control signal.

This Pure Direct system is based around the concept that higher transmission levels mean reduced loss of small signal, reproducing the intentions of both composer and performer down to the most minute musical detail.
External volume control is available from the H-VC5 volume controller or from our RPA-P7 preamplifier.
