In Norse legend, Ragnarok was the “end of the world.” Spring is in the air. What better time to review an end of the world integrated amplifier from Schiit Audio?
The Schiit Ragnarok 2 Nexus Integrated Amplifier — Fully Loaded — means that, in addition to an integrated amplifier, the Ragnarok also includes a MM phono preamp and a True Multibit DAC. There’s also headphone amplifier delivering full speaker power to the balanced headphone outputs. Let’s call this a full fun(tion) integrated amplifier.
New for the Ragnarok 2 is Schiit’s differential Nexus™ gain stage that 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.
The Ragnarok 2 delivers 60W into 8 ohms and 100W into 4 ohms, 24W into 32 ohms for the balanced headphone jack, and 6W into 32 ohms for the single-ended headphone jack with selectable gain to mate with whatever ‘phones you choose to plug in.
The Ragnarok looks like a Schiit component, albeit a bit more dressed up as compared to their lower cost models with its curved steel chassis that comes in silver or black. A nice chunky matching, if you picked silver, metal remote is included.
The Ragnarok is designed and built in California, which is in the USA.
In an interesting twist of fate, Schiit makes a full suite of measurements of the Ragnarok, and other products, available as a PDF for interested parties. I view this as very useful information as it goes a long way in showing that the Ragnarok is a well engineered and executed piece of kit. Armed with this kind of data, buyers can rest easy, along with reviewers, without fear of being called out for enjoying something that doesn’t measure up to some people’s expectations.
Here’s the opening Note from the PDF:
This is a test of a representative sample. If you have measurements that differ significantly from these, first check your analyzer and setup carefully, and (ideally) see if you can replicate the results on another analyzer. If the odd results persist, contact firstname.lastname@example.org so we can have a look.
As more people offer measurements as part of reviews, which can have very mixed results as we’ve seen in Certainly Uncertain Parts One and Two, other manufacturers may want to consider following Schiit’s lead. Best case scenario, this will help improve the current signal to noise ratio.
