Ragnarok 2 is the only modular, remote-controlled integrated amp that’s a great match for both speakers and headphones. Delivering full speaker power to the balanced headphone outputs, and debuting our all-new Nexus™ differential gain stage, Ragnarok delivers performance that completely befits its name—in Norse legend, Ragnarok was the “end of the world.”
Modular Flexibility, Remote Convenience
Ragnarok 2 has two module slots that accept the same modules that many of our other products use, for flexibility and future upgradability. You can order Ragnarok 2 in one of two ways to suit your needs:
Just An Amp: with two RCA input modules installed, for a total of two balanced inputs and three RCA inputs, ready for you to add all your line-level sources
Fully Loaded: with a MM phono preamp and a Multibit DAC, for a total of two balanced inputs, one RCA line-level input, one RCA phono input, and one USB DAC input—a single integrated solution for a variety of analog and digital needs
Both versions come with a standard milled aluminum remote control that allows you to select source, control volume, select headphone or speaker output, mute, and set gain.
Nexus™: One Stage To Rule Them
Ragnarok 2 debuts our unique differential Nexus™ gain stage for seamless interaction between single-ended and balanced sources. Nexus converts single-ended inputs to balanced outputs, and balanced inputs to single-ended outputs—in a single gain discrete gain stage, without gain differences between modes, and with good performance in all modes.
Power and Control for Speakers and Headphones
Ragnarok 2 delivers 60W into 8 ohms and 100W into 4 ohms, for excellent performance with most speakers. It also delivers full power through the balanced headphone jack (24W into 32 ohms) and quarter-power output from the single-ended headphone jack (6W into 32 ohms). With selectable gains of 1, 8, and 25, it’s compatible with a wide range of speakers and headphones.
Easiest 128-Step Relay-Switched Volume, Ever
The benefits of a relay-switched stepped attenuator for volume are clear. Compared to a potentiometer, they give you essentially perfect channel matching and near-unmeasurable distortion. However, some preamps with relay-stepped attenuators confuse you with buttons and screens. Not Ragnarok 2. Ragnarok 2 has a volume knob that works just like a volume knob—just grab and turn. And if you use the remote control, the motorized potentiometer changes to match the remote setting.
Designed and Assembled in USA
By “designed and assembled in USA" this is what we mean: the vast majority of the total production cost of Ragnarok 2—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.
