The new Schiit Aegir Amplifier now shipping

This is Schiit co-founder Jason’s take on the Aegir’s design history:

Just because Aegir looks like Vidar does not mean it is like Vidar.

Look very closely at the components and the pcb layout, if your any kind of tech you will see what I mean, and if you know different, please put a link up that proves me wrong. As I’d love for it to have totally different topology??

Cheers George

George, your second image link appears dead.

Works for me, here they are again.

If you still can’t see it here it is using image hosting.

Must be my iPhone X. Same link still dead; other alternative link works.

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

@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.

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.
