Same old Schiit? Um, no. Welcome to Asgard 2! - Page 11

It's not an ideal match, as judging by the A2's specs, it looks more comfortable driving higher impedance headphones. AT the HE-500's impedance, it doesn't even max out at 1watt. The HE500 and other orthos can take much, much more than the A2 can put out.

Sorry for my technical ignorance, but how come A2 with its 1.0W / 32 Ohm cannot drive the HE500 with its 35 Ohm, while being "more comfortable" with high impedance Sennheiser HD 650 pumping "mere" 380mW into its 300 Ohm? I thought a full 1.0W is hell lot for headphones and the more Ohms, the less power an amp can pump into given headphones. I stand to be corrected.

Planar magnetics like the HE-500 and LCD-2 can take multiple watts without breaking a sweat. You wouldn't be making a dent as to what they can handle. That's why people tend to use them with speaker taps, to further unleash their abilities. The Asgard 2 doesn't come close to giving them all they can handle.

On the other hand, dynamic headphones handle a lot less power. For example, I believe certain Beyers only handle about 200mw of power. That's more in line with what the Asgard 2 can do depending on impedance, hence why I say it's more capable for higher impedance cans than say a current hungry planar magnetic. It's probably better to say that the Asgard 2 is better suited for dynamic headphones than planar magnetics.

For example, my Compass 2 does over 3watts at 32ohm, but 200mw at 600ohm. It's technically more proficient in driving lower impedance, though higher impedance still get plenty.

Correct me if I'm wrong, but isn't it easier on the amp to drive higher impedance loads than lower impedance loads?

Yes, but certain amps are specialized in driving either high or low impedance. For example the Bottlehead Crack, I believe is specialized in high impedance, while the EF-5 is specialized in driving current hungry, low impedance cans.

The Asgard 2 seems like a decent bridge, but not particularly for current hungry planar magnetics.

This was a huge surprise to us, because we've never had this problem before. That's what happens when vendors have to change processes. It was also critical, because almost all of our products rely on pressed-in standoffs on the PC boards for board location and grounding. The vendor now knows about this, and will be changing the chassis processing accordingly. 

 

So, every chassis has to be gone through, anodizing burnished away at the contact points, and tested thoroughly. Separating the chassis problem from a couple of minor parts changes (different manufacturer, same part, shouldn't make a difference but did) took a lot of work. Now, all is well, boards are flowing, shipping is starting in earnest.


If I understand correctly, this reminds me of what Grace had to do with the m902.  They removed anodizing to ensure contact:

Like I said now I have a reason to buy an upgrade. Hand the asgard down and upgrade to a balanced amp... an another unbalanced. Damn tax returns are going to be gone soon. HEHEHEHE YAY!

Say good-bye to your F5 button.
