Schiit Eitr

Schiit Eitr Works with Virtually Any Audio USB Source and DAC

Just connect your USB source to the Schiit Eitr’s USB input, and connect the Schiit Eitr’s coaxial SPDIF output to any DAC that accepts coaxial input. Now, you have complete isolation from source to DAC, together with a superb, low-jitter coaxial SPDIF interface for bit depths and sample rates up to 24/192.

USB, Solved: Gen 5 Technology

The Schiit Eitr features the same unique Gen 5 USB input technology as in Schiit's upgradable DACs. It’s simply the highest-performance USB input available today, with complete electrostatic and electromagnetic isolation (via transformers), self-power of all critical low-noise and rechecking sections, and separate, precision clock sources for both 44.1 and 48kHz multiples. (And if you don’t understand the technobabble, here’s the point: it works great and sounds great, too.)

Linear, Low-Noise Power Supply—Built In

You won't need any "linear supplies" or other "add-ons" to improve the Schiit Eitr—like all of Schiit's stackable products, they've built in a linear supply with multiple stages of ultra-low-noise voltage regulators. From the included 1.5A, 6VAC wall-wart to the output, there are no switching supplies in Eitr.

Made in USA

By “Made in USA,” they mean Made in USA. Not “we just put in the last screw and said, ‘Assembled in USA.’

Why would I need a USB to SPDIF converter?

You may not need one at all. We’re not saying you are. If you’re already using our Gen 5 USB input, then you probably don’t need Eitr. But if you have a DAC without Gen 5, and you want to use your computer (or tablet, etc) as a high-performance audio source, then you might really like to have a USB to SPDIF converter.

What does this thing do exactly?

It converts USB audio to SPDIF (Sony/Philips Digital Interface Format), which is a dedicated digital audio format, and passes it along to your DAC by way of a coaxial output.

But are you saying I need to get this thing if I have a DAC without your Gen 5 USB input?But are you saying I need to get this thing if I have a DAC without your Gen 5 USB input?

Nope, not at all. Most USB outputs work fine with all of our DACs, no matter they have Gen 5 or not. This is simply another option that offers total isolation from the source.

What if I want optical?

If you want an optical output that has jitter problems like no tomorrow and likely cannot do 24/192 reliably, you’re free to find a different USB to SPDIF converter that offers optical output but we do not do one.

So does this replace the Wyrd?

No. Wyrd is a different product, used if you have noise or USB connection problems on USB inputs before Gen 5. You won’t need it with Eitr, since it’s electromagnetically and electrostatically isolated. Wyrd still solves problems on other DACs, though, so we’re continuing to offer it.

Gimme some technical details.

Eitr does three things:

1. It offers electromagnetic and electrostatic isolation from the USB source via a unique transformer-coupling method. This, we’ve found, is superior to optocouplers, which are inherently high-jitter devices.

2. It eliminates any connection between the USB power and ground and system power—Eitr's low-noise and rechecking sections are completely self-powered.

3. It provides much higher quality, independent crystal-based clocks for the USB input and SPDIF output, operating at both 44.1 and 48kHz multiples.

What if I want a super-duper linear power supply to really turn this thing up to 11?

Cool. We've already included it.
