The RPA-MG3000 is the largest stereo amplifier in the stable of this extraordinary Japanese firm. SPEC has set itself the goal of building amplifiers that can compete with the finest tube amplifiers. The makers of SPEC are themselves lifelong fans of (single ended) tube amplifiers. The RPA-MG3000 consists of two large enclosures, one for the power supply, the other for the amplifier electronics.
SPEC calls its own volume control method the: Pure Direct Connection, as you can see in the picture below. As so often, a picture says more than a hundred words. Let me put it this way: I find it, especially in view of the experiences that can be read further on, all a bit of sought-after hassle.
Surely an ‘ordinary’ preamplifier is much more convenient to use? Yes, it certainly is. When using a preamplifier, the control electronics in the RPA-MG3000 for the volume are put out of service with a switch on the back of the amplifier housing to turn it into a real power amplifier. We’ll get to work on it….
