Spec Corporation RSA 717EX Integrated Amplifier

The quest for our Real Sound Amplifiers (RSA) started with the efficiency of our new Class-D amplifier is so high (more than 96% at full power) that the quality of the power source has directly much effect on the final driving power and the sound quality of this amplifier. This time we used the potential of newest switching controller device to surpass the sound of a traditional analogue design power supply. And in further pursuit of higher sound quality and more natural tonal character we adopt newest SiC (Silicon Carbide) schottky diodes, special audio use electrolytic capacitor, custom oil filled capacitor and ultimate quality mica capacitor. It reached at the well damping, also massive low range and also fine transparent mid to high-end fully free from switching noise.

Thanks to the improvement of semiconductor technology, the integrated device composed of an advanced audio controller IC and two power MOS-FETs fully optimized audio performance was released from International Rectifier, IR in Calif. in 2012. We found the tremendous sound potential of this device and have been seeking to make best possible use of it with our extensive knowledge and experience drawn from our time at the Pioneer Corporation.

The main portion of the Spec-corp RSA 717EX amplifier is very compact sized PCB, requiring shortest wiring pathways delivering the ideal switching characteristics. Accordingly the sound could be natural and at the same time full of dynamic freedom. Also this fully exploits the amplifiers is superb higher efficiency compared to traditional semiconductor linear amplifiers. Powerful driving power for speakers and superior power saving ability could be easily encompassed all together in our Real Sound Amplifiers.

Spec-corp have produced a very special designs and construct incredibly efficient digital amplifiers which are superbly involving and demonstrate a real musical soul, a trait thus far which has eluded the vast majority of Class 'D' amplifiers. Not so the Spec-corp RSA amplifiers which were made for the single purpose of being soulfully musical:- The Spec corp Real Sound Amplifiers.
