Driving HiFiman Susvara with Speaker Amplifier

[jonathan.lesser]

After finishing and having a great time building the Mainline headphone amplifier, I am looking to build something to drive my Susvara's. 60 Ohm impedance, 83 dB.  Does anyone know if the Stereomore II would work, and if so, which upgrades would I be looking for?  I would plan on putting a preamp in front for volume control.  Thank you in advance!

I can't find a recommended power spec. I would guess that the Kaiju might be the best match. Being as it's a $6K headphone, seems like it deserves the best you can throw at it.

Also just want to point out that the Stereomour 2 does not require a separate preamp for volume control. The Kaiju, however, will benefit from one.

Thanks so much Doc

Doc, would you mind giving me some idea of the time and complexity of Kaju relative to the Mainline kit I just completed?

[Paul Birkeland]

A Kaiju build will take substantially less time than a Mainline.

Thank you Paul. You can believe that if it has heat sinks I’m not going to forget them.

Hello everyone, a question about using the Kaju with my headphones, would I need a full impedance adapter to use this?

[Paul Birkeland]

I'm not sure what a full impedance adapter is, as doing a web search for it doesn't really return any results. 

If you want to use fairly power hungry headphones with a Kiaju, you can run them right off the speaker taps.  If you want to use really sensitive headphones with the Kaiju (which isn't a great idea in my opinion) then using a resistive voltage divider at the output is a good idea.

There is more misinformation on this topic than probably any other, so don't hesitate to continue the conversation if you have additional questions.

Thank you very much
