The new Schiit Aegir Amplifier now shipping

@celander  

It appears @georgehifi would rather be right than try to understand how Aegir is not like Vidar and is more like the Lyr 3. No, not in size or components uses...but in design. The Head-Fi post you link to describes it well.

By the way, I really like the sound I get from the Lyr 3 and people I know that have access to Aegir really like it for the price point.

check out the head-fi link. It’s not a picture but an explanation that’s likely better than a picture.

As I thought the same "basic circuit topology"

Here’s what I envisioned when Marv suggested doing a low-power, “Class A” amp in the Vidar chassis:

• A 20-25W into 8 ohms stereo amp that would also be able to do 80-100W when run mono
• It would use the same basic topology as Vidar
• However, the addition of a Continuity output stage would result in a more linear output
• It would also use as much the same parts as Vidar as possible

"Continuity" output stage, is a "word" used which to me indicates the pnp/npn outputs don’t totally switch off (Class-A), so there’s no cross over distortion, like what happens in a Class-A/B amp when it enters Class-B.
You could say that about the Vidar also up to 5watts, that it’s also a "continuity" output stage up to 5 watts with no crossover distortion, then goes Class-B.
The reference to the Lyr is that it stays in "Class-A" like it does, which is the norm for any phono or headphone amp. But the circuit topology Marv suggested is Vidar.

It’s helpful to read beyond the first paragraph in most, if not all, of Jason’s writings. As much as he is a talented EE geek, he’s a very talented writer having a very substantial background in that arena. Besides, it would be a far shorter chapter had he given the punchline in the first few paragraphs.

And I think that reading the entirety of his writing there will correct your misapprehensions about what Schiit’s Continuity actually entails.

Except you left off the header text before the text you provided:

"Aegir the First: The Original Idea"

Guess what, the original idea didn't work out. Also, the output stage is not the same basic circuit topology as Vidar. The transformer used is significantly different too.

Vidar does 1 watt at Class A....

But hey, it all looks the same so it mostly is, right? 

I’m not bagging this amp celander, there is a great place for it in the market, using efficient speakers. But let’s not make it the holly grail, it’s not!
Nothing new there celander, it’s what’s been the norm on most good class-A complementary output stage push pull amps.
This "continuity" is just a new word used to make it sound like it’s something new and innovative.
Cheers George

The transformer used is significantly different too.

Of course the transformer will be different, the Aegir has to have far lower rails than the Vidar, my 10 year old knows that!!!
