I use cans and I never really made a big deal of the pop it's not all that loud on 50 ohm headphones or even 32 for that mater

for cans, I would not worry about. I'm worried about IEMs with 18ohm and close to 120sensitivity.

The pop doesn't seem to bad with most of mine - but I agree it is better to be safe than sorry so I have started to turn it on first then plug the IEM in.

Anyone in their teenage years confirm a high pitched sound using output1? I asked my dad to listen to it and he said he couldn't hear the high pitched "peep" sound that I was hearing. I asked polleychen about this but I don't know if he understood what I was saying.

if you can hear it then its there.  
 
Higher frequencies are lost with age.

Is it a constant sound or just momentary?

It's constant. I already mentioned this in the thread, but even when it's not plugged into the source, I hear this high pitched "peep" sound. I actually asked my music teacher as well and he said he couldn't hear it I'm still 19 and can hear the mosquito sound so I think it's just my ears.

That could very well be the case.  Keep the volume at safe levels, you only have one set of ears.  I have that same sound in my ears (tinnitus), though my hearing is still excellent.

I can hear mosquito sound too, i also can hear what my daughter whispers to my wife in another room, i can hear more than would be normal... But i do not hear high sound pitch. all i can hear is tiny hiss when no music playing but then my floorstanders also produces hiss when amp is not playing... So what's the fuzz?

As regards ears it could be a problem only if that high peep sound rings in your ears even after the amp is switched off, otherwise no problem. :-D

Anyone else feel that the volume is a bit too low? If I try using out2 or highgain off, the volume is too dang low. I have to literally crank it all the way to the top.

Even on Out1+highgain on, my source volume is at about 70% and my bh amp volume pot is at about the 10 o'clock position.

My hearing is fine. It just seems pretty quiet.

The noise you're hearing should not be there, I do not doubt your fathers ears, only we would have several more reports of this coming through from all the buyers, I know a member who is only 16 and his BH amp is dead quite to his ears, there is a fault with your amp. I know it seems like a hassle to get it replaced and go through an exchange with Pollychen, but you will be happier you did this in the end.

Turn your source up to 100%

Thanks for the tip.  Wow, I had a brain fart and didn't even think of that.
 
I've been using it for about 3 days now and I am truly impressed.  The soundstage, the details, etc.  It's all just amazing.  It's making me re-listen to my whole music collection again.
 
One thing though that I noticed, if anyone can chime in.  The BH seems to pick up EMI quite easily.
 
I have it double-locked to my Galaxy S3 so it's literally piggy-backed.  It's silent during normal usage.
 
But the times where I can hear the EMI noise come on for about 4-5 seconds is when there is some type of "activity" going on in the phone.
 
For example:  I tried turning off the Wifi and the EMI noise came on again for about 5 seconds.  It then went dead silent.  2 minutes later I tried turning on the Wifi and the EMI noise came on again for about 5 seconds.  Seems to happen when it tries to connect or disconnect to a Wifi spot.
 
Anyone else notice this?

Cool - finally got it!
 
First impressions are "Wow - love the size! Much smaller than the E12, and even smaller than the E11. Cool - this will work very well as a truly portable amp."
 
Second impressions are "Wow - lot's of buttons/options - where's the english in the manual lol!".
 
So now I think I'll read through this thread to find out what the various settings are, and which settings seem to be the most popular.

The LF switch boosts ur low end and the mids so I always keep it on, the SF switch widens the sound field quite a bit (better for older more condensed recordings particularly pre 1990) if u use the SF switch on a live recording it sounds amazing. Just don't use it on new music to much cause it separates the sound to much. And finally ur gain switch just let's you decide how much power your headphones require. If you want to know about the difference between output 1 and output 2 then message H20Fidelity

Thanks! Which "out" do you use? Edit: I read the OP, and I'll stick with "out1" for now.
 
Btw, I am starting out the C&C BH testing journey off of my ELE DAC. Based on what I have read already, and based on how much I love the AD900X's through the ELE DAC + E12, I highly doubt that the AD900X's will sound better through the C&C, and I am envisioning that I will continue to use the AD900X's with the E12. But, I will of course be testing that out.
 
Where I am thinking the C&C might shine though is with the ELE DAC and the WS99's. They are closed, have an incredible bass and balanced sound, and they don't benefit as much as the AD900X's do with the E12 because the soundstage seems to narrow a bit, and the sound might become a tad bit warmer.
 
So, I'm hoping that the WS99's really benefit from the C&C, where a bit more brightness won't hurt, and the soundstage won't be narrowed. And I'm hoping for this not only off of the ELE DAC, but off of my Clip Zip (I was using the Clip ZIp + E11 + WS99 when moving about). So we'll see!
 
My one concern will be with my iem's off of the clip zip + C&C - I'm hoping that they don't become too sibilant for me because I'm treble sensitive. Again, we'll see!
