Schiit Asgard and Valhalla Headphone Amplifiers

[Leo Yeh]

Asgard
SINGLE ENDED CLASS A FET HEADPHONE AMPLIFIER
ZERO FEEDBACK | SINGLE VOLTAGE GAIN STAGE
$249





Asgard is a fully discrete, Class A, single-ended FET headphone amplifier with no overall feedback and a noninverting circuit topology. Its high-current design makes it uniquely suitable for low-impedance headphones.

Now, if you’re an engineer, the preceding paragraph probably means something to you. For everyone else, let’s simplify it: Asgard will sound friggin tremendous on virtually any headphone you throw at it, from $39 cheapies to those $1400 monsters you’ve been wanting to try. Asgard will even drive them to ear-imploding levels, if that’s what you’re into. And Asgard will do this for years and years, with no maintenance or tube replacements.

5-Year Warranty
Asgard is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Compare that to the competition.

15-Day Satisfaction Guarantee
Don’t like your Asgard? No problem. Send it back for a full refund within 15 days of your original purchase. When was the last time you spent a couple of weeks in an audio store? With your own equipment? Thought so.

Valhalla
Single-ENDED TRIODE OTL HEADPHONE AMPLIFIER
ZERO FEEDBACK | NONINVERTING
$349



Valhalla is a Class A, single-ended triode headphone amplifier with no overall feedback and noninverting circuit topology. It provides classic tube sound and can drive headphones with impedances as low as 32 ohms.

Yes, we know that all you got out of the preceding paragraph is probably, “Classic tube sound.” And if you’re not a tube junkie, you might not even know what that means. Well, let us explain. Tube sound is a smoky nightclub with a hot chick in a red dress, it’s a warm swimming pool in summer, glowing green against the purple twilight, it’s a . . . well, hell, you can’t really explain tube sound. Think “smooth, fluid, liquid, alive.” But not in a SF-movie-gonna-eat-you kinda way. Valhalla delivers warm, magical sound for most headphones, as long as they aren’t less than 32 ohms.

5-Year Warranty
Most of Valhalla is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Compare that to the competition.

The parts that aren’t covered by a 5-year warranty: the tubes. Tubes are covered by a 90-day warranty. They should last between 3000 and 5000 hours, but they do wear out. They will need replaced. Do not panic. Humans lived for many decades with this technology.

15-Day Satisfaction Guarantee
Don’t like your Valhalla? No problem. Send it back for a full refund within 15 days of your original purchase. When was the last time you spent a couple of weeks in an audio store? With your own equipment? Thought so.

我建議各位去讀一下這家公司的網站上的FAQ http://schiit.com/schiit-faq/general-questions/
真的蠻好笑的。 另外值得一提的是，這家公司的兩位設計者發燒友應該不陌生（Sumo 的 Jason Stoddard 和 Theta 的 Mike Moffat）。 我想我搞不好會試試他們的產品（雖然他們的公司名子蠻搞笑的）。

[Leo Yeh]

yes，他們蠻幽默的

剛剛 pre-order了一台Valhalla

接著是該找一付耳機了

[kevintran]

據Schiit說，Valhala適合AKG的高階耳機..... AKG801 or AKG701?
老實說，我也很心動（AKG701用家）。 請問他們有沒有說大概何時會到貨？

我記得網站上說八月 現在Schiit只給我一個Google Checkout的Invoice，詢問結果是等通知後再結帳吧.......

大大請來些開箱照分享呀.....我也覺得這價位很實在

Lyr
HYBRID HEADPHONE AMPLIFIER
DYNAMICALLY ADAPTIVE | ZERO FEEDBACK | NONINVERTING
$449



VERY IMPORTANT: LYR IS IN PRE-ORDER. WE ANTICIPATE SHIPPING BY MARCH 1, 2011. If you order now, your card will not be charged until the amp ships. Please check out the Lyr FAQ for more info.

Lyr is a extremely high-output headphone amplifier with a new Dynamically Adaptive output stage that provides high voltage output into virtually any headphone—up to 6 watts into 32 ohms—while maintaining excellent overall efficiency.

Now, if you’re a headphone guy, you’re thinking “Holy Schiit! 6 watts! That’ll make the magic smoke come out of my headphones! Why the hell do you need that kind of power?” Well, we have one word for you: orthodynamics. And two more: Why not? If everyone wanted polite little low-power headphone amps, this would be one awfully boring world, wouldn’t it?

That said, Lyr isn’t just about brute force. Sure, it has dynamics to spare, but it also delivers music with grace and finesse. Its hybrid design uses ECC88 tubes for the input stage, and the topology is DC coupled at the input and output to ensure the purest, most direct signal path.

Make no mistake: even though Lyr is the same size as Asgard and Valhalla, it’s one of the most powerful headphone amplifiers you can buy. We will not be responsible if you blow up your headphones with it!

Dynamically Adaptive Output Stage
No. Don’t roll your eyes and dismiss this as marketing bullschiit. Our new Dynamically Adaptive output stage allows us to pack almost 6X the output power of Asgard into an amp that runs slightly cooler. (Now, that doesn’t mean it runs cool. If you want a cold amp, you need to look elsewhere.) It works by sensing the current flowing through the output stage, and dynamically reconfiguring from Class-A single-ended to push-pull Class AB. The result is both pure Class-A sound and the ability to drive virtually any headphone, including low-impedance and low-efficiency models (orthodynamics, we’re looking at you.)

Roll Your Own
Lyr ships with JJ ECC88 tubes, but feel free to substitute any 6DJ8, 6922, or ECC88 type tube, new or old, American or Russian or Chinese. The ability to use different tubes lets you tune the overall sound signature of Lyr to your specific needs.

5-Year Warranty
Most of Lyr is covered by a limited warranty that covers parts and labor for five years. That’s 5 years. Yes. FIVE. Compare that to the competition. The parts that aren’t covered by a 5-year warranty: the tubes. Tubes are covered by a 90-day warranty. They should last 5000 hours or so, but they do wear out. They will need replaced. Do not panic. Humans lived for many decades with this technology.

15-Day Satisfaction Guarantee
Don’t like your Lyr? No problem. Call us for an RA and send it back for a full refund within 15 days of your original purchase. When was the last time you spent a couple of weeks in an audio store? With your own equipment? Thought so.
