Anyone heard Schiit's Aegir?

@mlsstl  - That's helpful about the volume. My speakers are 89db 6ohm (Aperion Verus III Grand Towers) and I was wondering if a single Aegir could drive them comfortably up to 95db continuous or so. It sounds like it will be possible. How high was your preamp turned up?

The thing to remember about amp power and volume is that the wattage is a logarithmic relationship to loudness, not linear. Each 3 dB increase in volume level requires double the power.  

In my case, if 2 watts average = 85 dB, going to 95 dB would need more ln the neighborhood of 20 watts, perhaps a bit more. And you still need some extra for dynamic peaks.  You might be asking for for close to full power from the Aegir with little room left for peaks. I just don't listen that loud.

There is also the issue that speaker impedance is not a single number across the board. The resistance varies with frequency and some speakers are more difficult to drive than others. And, there are multiple ways to measure speaker efficiency, so sometimes a manufacturer's numbers are a bit optimistic. 

However, all you can do is try. You might also consider running two Aegirs as monoblocks. You get 80 watts a channel into 8 ohms that way, but you'd need a preamp with balanced output for that to work. Schiit does offer a 15 day money-back trial period (less 5% restocking fee and return shipping costs) so you do have that option if you want to experiment.

I wouldn’t do that, yes wattage goes up, but all other properties go down, when you bridge.

Much preferable way if the speakers have bi-wirable speaker terminals.
Is to horizonal bi-amp, using the stereo Aegir in it’s Class-A glory for the uppermids/highs that’s it’s forte, and then a using a much more powerful Vidar for the bass.
And a $49 Sys passive to equalize the gain of both because they have different gains No bridging and no loss of quality on either.
They are very similar in circuit design and will sound as one, just the lower wattage Class-A Aegir is being used where it shines, in the uppermids/highs and won’t be stressed trying to do bass also, that’s up to the Vidar.

Thanks, George. That's a good idea for those who listen at loud volumes and have speakers that accommodate using two amps configured as you suggest. However, that wouldn't work for me. Ohms have just one driver that handles the whole range up to 8K or 9K and then use a single tweeter to supplement above that, with only a single set of terminals for both drivers.

Fortunately, for my preferred listening level the Aegir is proving to be a great choice for me.  I'm continuing to experiment with a wide variety of music (with the meters still connected) and haven't found a situation yet that seems to stress the amp or demand more power than what's available.  Obviously whether that works for others is something they'll have to check out themselves.  Those who want high volume will be out of luck with a single Aegir unless they have very efficient speakers.

No, that bi-amp’ing configuration, is not for getting louder music, bridging two amps into mono is, but looses out on quality all over.
It’s 20w of Class-A still for mids and highs with the Aegir, just not making it do bass, which the Vidar would be better at anyway.
