The used to be true, but now there is the Jotunheim, which must be causing the other HP amp manufacturers to scratch their heads
Well the Jotunheim only does what, 5watts max? Vs. the 14w max (I think) the iCan Pro does. I could be wrong and the Jotunheim has more power, but the 5 watt number rings a bell. They aren't really that comparable.
The Mjolnir 2 and the iFi iCan Pro are more comparable as both have tube vs full solid state options (via the LISST tube thingies.) I listened to the Mjolnir 2 and the iFi iCan Pro back to back, and the iFi wiped the floor with the Mjolnir 2. It wasn't even close, the iFi was SO much better. Granted I was listening to the Mjolnir 2 with the stock tubes, not LISST SS tubes, and was listening to the iFi in SS mode. The Mjolnir might be better with better tubes, or with the LISST I don't know. I haven't heard the Jotunheim yet, but compared to the Schiit amps I have heard, I would go with the iFi every time.
