Measurement results using switcher brick (more current limited than the external supply):

Output Impedance: 0.1 ohms (I need to double check this. It's definitely way way less than 1.)

With HD600 as the test load, nominal 300ohms (we use headphones instead of resistors, don't try this at home):
  • 1Hz to 300kHz -1db
  • 1.3 Watts
With LCD2r2 as the load, 58ohms:
  • 1Hz to 250kHz -1db
  • 3.6 Watts
BW with external power supply shipped to Zero for the tour.











*splutter* Oh shit. And this thing is $800+s? Uh oh. Just uh oh...

Is the topology a secret?

you better buy a unit. There's only 10 in the first batch and after that the pricing goes up. $1197 is ridiculous. I've spent that much just on portable amps in the last year...

For tube amps, fine. This one... absolutely no way. You can buy one and try to trace the circuit.

And meanwhile us Canucks are wondering if we can sneak one across the border somehow...

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin

Could we get some pics up? For those of us who were unable to make it to the meet. Curious what this beauty looks like

there's a front facing photo on the Eddie Current web site.

I'm more interested in photos of the back side.

If we order one without the external power supply in the 2nd run, will we have an opportunity to add one in the future?

No longer an option. Power supply comes with it. Don't want to deal with returns from people blowing up their amps.
