Ray told me a few days ago that he's found a way to get it down to one knob. This is great news and it certainly gets me interested. He also said that he's waiting on parts and that he hopes to have them shipping by Christmas.

My limited understanding is that when you take a balanced signal and convert it back to S/E you have the option to tie the "-" to the ground or simply leave it disconnected.  In the old days baluns were used for this purpose in some applications.  I have no idea how they do it these days especially what design Ray uses.

So I have a question... when you use a SE input it flips the + to create a balanced signal right?  If the amp thinks it is getting a balanced input with a + and - already when the -'s are a shared ground, would it skip that part or what?

I haven't heard anything for some time. There must be something good going on.

i heard this amp at rmaf (the latest prototype) and ray almost had to pry it away from me. i think the sr71b is rays best work ever !
the qualities of this amp that really stood out to me were (1) no noise that my ears could detect. i have extremely sensitive ears,and the sr71b sounds like a discrete design! i cant believe this thing has opamps in it. this amp is really clean sounding. (2) the soundstage is massive!  wider than protector in balanced mode! i brought my jh audio jh-13 iems that i used in balanced mode with sr71b. this combo has the best synergy together i have ever heard,with my jh13. it is sweet and liquid sounding.
i look forward to pre ordering this amp.
also, i really like the (single) back to back dual pots! i only wish i had brought my camera to take pictures.

It's not gonna be under $600. 3 time the complexity of the Protector does not come cheap. Ray, I will (attempt) buy one if I'm wrong...

do anyone knows whether it will be available by the end of this year??
and What balance port is ray going to use? will it be the same as the one in Protector?

From what I understand it will be available by the end of the year or most likely before and the connecter is the same as the Protector. I have been using the connector quite a bit and it shows no signs of wear and has endured a lot of rough care.
