//The Ultimate Truth

The Ultimate Truth

So our pilgrim moves up to the peak of the mountain. Here he encounters the pinnacle of perfection. Vast sonic vistas spread out in every direction. The eagle, whose visual clarity brings into focus all that surrounds him, is a worthy companion for the Ultimate Truth. From the lowest note on the of the lake’s motion to the whistle of wind that soars beyond hearing, the Truth is the holographic master of this entire realm. Without subtraction, without addition, the Truth presents all to the ears of those who have traveled this far to achieve perfection. With sonic nirvana permeating every cell of his body, our pilgrim delights in the best the world has to offer. If it is the thunder of the 1812 Overture or the sparkle of the notes from a harp string, every minute aural fiber is presented in its full glory. The Truth is here… come and experience it.+  Ultimate Truth

Description

Whammerdyne Ultimate Truth 2a3 Amplifier

The Truth™ amplifier, which combines the beautiful tonality of a zero-feedback, direct-heated 2A3 Triode’s with the speed, presence and immediacy of an ultra-wideband amplifier (6 Hz to 140 kHz). The Truth™ amplifier has a wider bandwidth than any analog source, and any digital through 196/24. Part of the reason for the extraordinary bandwidth is the complete absence of coupling capacitors and cathode-bypass capacitors in the Truth™ circuit. All tubes operate in fixed-bias mode, with very low source impedance’s in the cathode circuit, and they are connected by the innovative Z-Direct Interface©, which has zero phase shift, does not store energy, and provides instant recovery from clipping. It’s a difference you can hear and enjoy for the life of the amplifier. Speaking of life, the Truth™ has a precision bias circuit that lets you optimize all of the tubes for optimum sound and the longest possible life. Although the Truth™ amplifier is ready to plug-and-play, thanks to the extended burn-in and testing at the factory, there’s an optional bias setting procedure that lets you dial-in the bias to any good working set of 6DJ8 and 2A3 tubes. Do you have a personal favorite set of 6DJ8’s and 2A3’s? Bring ‘em on! The multi-function bias meter, unlike a conventional type tube testers, measures the tubes in-circuit, at the actual voltages and currents of the working circuit, so you can be confident all tubes are operating at the exact optimum parameters. We’ve poured our dedication, love of music, and decades of engineering talent into this amplifier. Welcome to the Truth™! The best 2A3 amplifier on the planet
