I tried searching the forum, but seems no one has yet done a detailed comparison of pb2 and sr71b. Eagerly looking forward for the same.

You might try sending Jamato8 a PM as he has had both for quite some time and can probably give you a very unbiased comparison.  Although I have owned the Predator, PB1 and PB2, I have never heard the SR71b so can't provide any help there.

"Now, what about the sound? The primary difference between the two amps is the sound signature, where the SR-71B maintains a warmer, darker, and heavier bottom end sound, the PB-2 less heavy on the bottom though not light and more low treble presence. Of course, while rolling opamps, you can “EQ” the PB-2 to be more trebly or more bassy, depending on what you’re using on the opamps and buffers. But even at the “darkest” and fullest bottom end setting with the stock opamp kits, the SR-71B still has a more solid bottom end body that I couldn’t find on the PB-2. On the other hand, if you are more into trebles, then the PB-2 will probably be a better suit for you."

hey guys need help.. trying to diy a balanced cable, but not quite sure how to open up the hirose connector?
 
anyone help out a noob?

 

[Saintkeat]

thank you!! i just did it and it worked! i think soldering it would be very challenging!

 

[Saintkeat]

roger.. got that.. but what kind of cable did you use? i'm thinking of going with 28 awg solid core silver. the opening seems really small thats why i don't think i can use a 24..

When you solder use female with the male because when you heat the pins you solder to they can move in the plastic when it is hot and they will no longer be aligned. If the plug is inserted then the pins will be held in place. 

 

[Saintkeat]

oh so what you're saying is i should plug it into the amp and solder when its plugged in? sounds good.. i guess the only risk would be pulling it out before its cooled off..

 

[Saintkeat]

HAHAHAA gosh i feel stupid. ok. i'll try doing without then.. the size of those contact points require a surgeons hand! i'll do my best and post back here...

Before I used an extra female plug I did have a couple of pins float some and I use a hot tip temp controlled iron and I know that iBasso also does this. I have soldered many of these and I just find it safer and easier plus it is easy to to a continuity check to double check for correct wire placement and a good solder.

The PB2 Topkit has at last been finalized and "Rocks".

Quick question that I'm not smart enough to figure out:
 
Will the PB2 running balanced push my HD650s as loud as my Fii0 E9?
 
The only numbers I can find for the E9 say: 1W at 16 ohms; 80mW at 600 ohms.  The Pelican says: 2500mW Max. (at ?); 32 Voltage swing.  (None of this means anything to me.)
 
If this has as much (or more?!) "grunt" as my E9 I think I shouldn't deprive myself any longer.  If it's going to feel weaker/quieter, I may still go for a more powerful, SE desktop.

 

[jamato8]

The rating is at 32 ohms and it would be much more powerful. I also find the HD650's to sound better balanced and out of the PB-2, it will go louder than you could ever listen but more importantly, it will sound good. It is more powerful than many desktop amps.
