Whenever Ray posts his announcement/pre-order thread, can someone link here?  I don't always check the MOT forum.

I resized them as they take forever to view and this way they are easier to view. Hope you don't mind.

In the meantime, there should be no reason why a Hirose Male-to-Protector Male Balanced IC could not be built to enable using the Boomslang with the SR71B, just like with the PB1 Toucan.  I'm assuming the SR71B chassis dimensions to be roughly similar to that of the PB1, but I could be wrong.


Yes, this is easily done.  It's a straightforward 4-wire cable (although unpleasant to build, let me tell you).  Both plugs are just L+ L- R+ R- but different shapes.  I plan to use my Boomslang with the SR71B when it comes out, and I have a Toucan to tide me over till then.  
 
Edit:  The only annoying thing with all this gear is 
a) the Boomslang's output is on its "front" so I have to run a cable from its front to the back of the amp, or else face its inputs forward.  It should be like a tiny version of my RE-7 with all the I/O in the back.  /OCD
b) the Protector plug is at a right angle, so when it connects to the SR71b input it will have to loop around 90 degrees to connect to the front of the Boomslang.  Perhaps it is possible to build a right-angle Hirose cable? That way it looks cuter.  The Hirose plug has a strain relief screw hole on the side of it, so this might be possible with some modding.

doesnt look like its going to be too much larger than the protector was
 
and damn look at all those op amps!!
 
and it appears he decided to go with one pot, but its looks like its only 2 gang...


It is 4 gang and you couldn't have a balanced input from the dac if it wasn't anyway. It is larger than the Protector, I would judge about 2.5 times the size. A powerhouse of an amp that's for sure.

Has Ray determine a price for the amp yet?  Sorry to be redundant if this has already been ask/answered.

Ray told me it will be about 1/2" longer and wider than the Protector, but it will be slimmer by about a third.

Yeah, it drove the HE-6s very well. My dad and I were impressed. One thing that jumped out at me was the soundstage, which was huge. It almost sounded like was a binaural recording, when I know it wasn't.

everything sounds better, fuller, and spacier after eating brownie lady's brownies...

I'm keeping my toes crossed as well, but the ~$600 price range seems in the ballpark and consistent with the pricing of Ray's past offerings in this category.  Maybe we get an intro price break--say, $50 off--but even with that this isn't going to be a cheap portable amp.
