I heard the SR-71B this Saturday, and while I wont be able to afford it any time soon, I can say it lives up to the hype. Ray had the tiny little thing driving the HE-6s effortlessly and I also listened to some balanced HD600s he had, and the soundstage on both was amazing. 


Do you remember where did Ray get his balance signal from to feed/drive the SR71b?  Was it a desktop unit or a portable unit.  In terms of portable unit, except the Boomslang from ibasso I don't know of any other balance dac that can output balance signal to the SR71b.

Are there any images from the meet? It would be nice to see a few.

Jalo, it was XLRs to the balanced outs from his four thousand dollar Meridian CD player. I also do not know of anything transportable that provides balanced outs other than the Boomslang, but stay tuned. Someone is sure to build one.

In the interim, something to consider for use with computer audio at least is the HRT Music Streamer Pro as it has balance outs. I believe Moon Audio even makes a cable with the balance connector Ray uses.

Is it possible to build a tube version of this amp ?

No. Tubes don't substitute directly for chips. Tube power supplies are an entirely different beast and much else. There are a number of balanced tube amps on the market, though. Also, you can balance just about any DIY amp if ypu want to go that route.

I've been waiting a long time for Ray to work on ANY type of DAC for portable use (which includes optical).

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.

The choices of dacs should be exciting. I have the feeling that the 71b will set new standards. 
 
A USB device that will do 24/96 to feed these amps would be welcome. Audio just keeps getting better and better.

 the Boomslang will do up to 24/192 as far as I know because of its WM8740 DAC chipset.  http://www.wolfsonmicro.com/products/dacs/WM8740/

The dac chips but not the USB chip, it is 16/48.

Absolutely! It is very a fun time for me, being young and all. I remember shortly before I joined Head-fi there was nothing close to this level, or value.
