An illuminated cloud bank still obscures the absolute Truth. But even the audiophile driven to perfection must stop and rest on this relentless quest. But the mind clothed with the gossamer wings of desire will only let down a little. Resting he becomes aware of two objects, like sentinels, pointing the route to the Ultimate Truth. Here in the realm of the mountain goat is revealed the RAM. Onto them the sun shines through with purity. This is sonic daybreak, showing the Truth of the landscape and the two remote transformers. These outboard transformers expand the sweeping horizons of sonic purity expressed by the DLM4+RAM for all who would approach. These heralds of a new golden age are steadfast sentinels on our way to the realm of the Olympus of Truth. Sonic purity awaits one in hearing the call of the best 2A3 amplifiers on planet earth.
DLM4+RAM | Damn Little Monster + Remote Advanced Magnetics
Whammerdyne “Damn Little Monster Amplifier” (DLM4+RAM) new for 2019
The new DLM4+ RAM (Damn Little Monster Amplifier + Remote Advanced Magnetics). The world’s first remote transformer high power parallel (Non push-pull) 2A3 tube amplifier on the planet. Sporting matched parallel 2A3 output tubes per channel and a huge upgraded power supply with high current low noise regulated filaments along with 7 other high voltage regulated ultra low noise supplies with a huge current delivery capacity. Never a time that the power supply will sag or even crack a sweat under any load conditions and they are hyper fast recovery, no slewing the impulse response.. we also have 2 options in output transformers available. We take another big leap with remote placement of the output transformers this allows for many advantages. First the wonderful technology of our Truth model carries through (please see the Truth page) now we add the option of the larger highest quality output transformers used in our flagship “Truth” model. (2 transformer options available) This unique approach has numerous advantages.
Moving the transformers away from the main amplifier chassis has many technical benefits. One of many eliminating magnetic coupling interactions with power supply transformers and other sources of magnetic fields and noise internal to chassis. Even in the best of conditions with careful spacing and orientation the output transformers are part of the amplifiers chassis and assembly this presents many unfavorable conditions, resulting in induced magnetic coupling and the increased levels of measured hum, noise and cross talk all contributing to a higher noise floor and higher distortion. Let’s take our “Truth” model and flagship of the Whammerdyne offerings that has a world-renowned low hum and noise level at under 70 micro volts (wide band) that’s millionth of a volt!) The reason we achieved this low level with the Truth comes in part from a very unique chassis design and the physical way we mount the power transformer and “Null” its interactions with the output transformers but there is a limit and that’s physical spacing the more space the bigger the chassis. While our remote chassis DLM4+ RAM and it’s remote transformers comes in at an astounding 30-50 micro-volts** wide band, that is over 130 dB down! (we actually have made some tests at zero!) the limit of our 6.5 digit lab reference test equipment.
What is achieved by this even lower wide band hum and noise? The lowest levels of the delicate music signal are revealed and reproduced without loss (Not masked or buried in the noise floor). In many cases (well most all) tube audio designs by other manufacturers having substantially higher noise floors (and they do!, that’s why they do not publish them) fine details, harmonics, spatial information, and phase information is buried and masked/lost in the higher noise floor. In addition, the power wasting (DCR resistance and inductance/reactance) and all the issues with speaker cables becomes a non-issue.(this actually improves the dampening factor with our remote transformers) That’s a huge bonus! Most manufacturers of amplifiers will not give you a noise floor or hum and noise measurement. Even if they do, it’s usually a weighted or narrow band of measurement that hides the fact that their designs lose low level information or alter/distort it with the interactions of the noise floor and the signal. In summation what we have achieved is the best of all worlds as our amplifier circuit technology designs, already the world’s finest DC capacitor-less , zero feedback and zero phase shift SE (Single Ended) amplifiers we just raised the bar with the lowest noise floor amplifier on the planet. “Once your hear it, you can’t unhear it”
