I don't know how many Mw at 300 ohms the amp can supply.
Dr. Lloyd Peppard, the designer and maker of the Mapletree amps, probably does. I've emailed him a few times with questions for which I could not find an answer on Head-Fi, and he replied with the answer I was looking for quickly and happily (with some very nice explanation to go along with it). He's a really fine gentleman. The link to contact him by email is on the Mapletree web site.

Can it play very loud into Senn 600/650? To me, yes.
I'm using a HeadRoom Ultra Micro DAC and a 5.5G iMod with ALO VCap dock as my sources. With Senn HD600 or HD650 attached, it's as loud as I've ever wanted to rock out to at 2-3 O'Clock on the pot (HR UMDAC) and at 4-5 O'Clock on the pot (iMod w/ VCap dock). I've never had a moment where I've wanted to turn the pot up more, but it was maxxed out. I've measured the SPL from the phones when listening "loud" to make sure that it wasn't so loud that I might be damaging my hearing, and the loudest I've ever measured was 75 - 80 dB. My listening SPL generally comes in around the mid sixties to low 70's on the dB scale. To give you an actual measure of what I'm calling "loud". When I take hearing tests, I test "normal", no measurable drop-outs nor any superacuities with respect to the general population.
As to the color scheme, I've got the black chassis with walnut side panels (which matches my collection of audio equipment, cased in black extruded aluminum and wood, really beautifully). What's the "decor" of the other equipment and the room in which you'll be using the Mapletree? From which look of the Mapletree would you find the most satisfaction, given the whole equipment + room "ensemble"? If you don't have a definite preference, do you have a significant other who might? Just a few considerations to help in choosing between two really fine, and different, looks for this great-sounding and versatile amp.
