Thought I would share that this is finally available.

$100 for an incredible little discrete amp.

I could add more about the sound but Dave Hanson's review pretty much covers it. Totally amazing that such a tiny box can deliver such a large and refined sound.

Thanks for the heads-up, dBel84.  I'd also be interested in the Liquid Platinum version.  Really like the preamp out and aux in.

As an aside, Massdrop also has run group buys on a couple of Cavalli HP amps.  Different cases, and probably different circuits.  I like the Monoprice version better as far as aesthetics go.

What are the power ratings at 300 and 600 ohms?

Only saw the 50 ohm spec...

Assuming no trickery in the circuit, you can just divide by 6 and 12 respectively.

no trickery - approx 250mW into 300R and 125mW into 600R  ... working off a conservative estimate of 1.5W into 50R
