Sure, you can do that no problem. It's actually stated in the specs and features.

That's a cool looking rig and cabling pwn (and a good photo)! And yes, the battery life of this thing is starting to freak me out, and is making my E12 feel a bit insecure lol. And as far as girlfriends go, I think I better try to wean myself off of this addiction before I bother even trying to get another. Hmmm... gonna be tough!

Yeah the cables look very good and feel very sturdy
They are from stage 93 and they are based in Singapore (:

I want to first thank everyone who's helped out a audio noob like me.

 

I've had the BH for 2-3 weeks and I really do enjoy this amp.

 

Just a couple of things that's been bothering me that I can't seem to shake off.  Maybe it's the OCD in me but, I just can't seem to shake off these issues.

 

1)  The whole EMI issue gets downright unbearable at times.  I know it's susceptible to EMI noise when paired with a smartphone (Galaxy S3).  But not even the buzzing sound but a crackling and loud pitched noise is prevalent in certain situations.  It always seems to happen when I'm in an elevator or when I'm in the stairs.  The EMI buzzing/crackling/loud pitched sound will just go crazy for a long time.  Even my Fiio E6 never had this much noise (granted it's made out of plastic so that may have helped.)

 

2)  The volume just seems way too low, especially on Out2.  After advice from H20, I put the source all the way up.  On Out1 with Highgain on (max settings for loudness) I have the volume pot at around 9 o'clock.  If I turn Highgain on I literally have to raise it to about 10-11 o'clock.  On Out2, forget it.  I can barely hear anything.  On Out2 with Highgain on, I have the knob set at around 12:00 o'clock.  On Out2 with Highgain off, let's just say, I can't hear anything.  I don't think my IEM's are hard to drive.  A ATH CKS77 and CKM50.  They should be pretty easy to drive.

 

My hearing is fine.  I'm not losing my hearing or anything.  The volume pot seems to be strange.  On Out1 from 6 o'clock to 9 o'clock, the volume increases drastically with a little knob adjustment. However from 9 o'clock on, the volume increase is very minimal even with increasing the volume knob.

 

Like I said, maybe it's just me, but these couple of "issues" are bugging me.frown.gif

 

 

Edit: In regards to Point #2 I just tried something that I wasn't thinking of before.  I probably should have done sooner (I'm dumb).  I tried testing it on my old iPad1 (which I haven't used in months) and well what do you know, the sound output is sooooo much louder on my iPad1 compared to my Galaxy S3 (with the Wolfson DAC).  I always thought the Wolfson DAC was pretty good on the S3 but, I guess not.  Jeez.  Seems like the volume on the iPad can go up 16 notches while the S3 can only go up 8 notches.

Sounds like you are trying to like this thing..................and I for one am glad to hear all the EMI issues you're having since I would be pairing this with an iPhone 5.

I updated my post above.

 

The issue with the volume wasn't because of the BH.  It was due to my source.  Something I should thought of but I didn't.  My dumb mistake.

 

Apparently my old iPad1 can output sound much louder than my S3.  So if you own a iPhone5 then you may be in for a good surprise =).

Still gonna have EMI "problems" with an iPhone 5, though.

Yeah, just tried this with my phone next to the BH, they didn't get along to well, if I'm correct the entire audio signal stops when I purposely made a call with them together, EMI is not uncommon amoung portable amps. Members who've been around a while are well aware of this, why we use Airplane mode. If you need your phone signal on, I suggest using a cheap sansa clip for the BH and your music for those occasions. You'd probably be surprised with the outcome.

I am really curious about all this as I was considering the BH to pair with my Galaxy S. EMI issues in an amp that was designed  to be paired with this type of device are totally unacceptable.

 

 Has anyone talked with BH about this? This seems like a typical ground loop issue. Perhaps a shielded interconnect would solve it.

I run my iPhone 5 with my FiiO E11 at times and have ZERO EMI problems so must be the C&C's problem. 

 

Thx for the info.

Yeah it was pretty bad. I can understand it would drive some people crazy.

That's not the Wolfson DAC that's the problem, but the headphone amp on the S3. Apparently Samsung has the headphone amp gain set low on some of their phones. I actually rooted my Samsung Note 2 and turned up the headphone amp gain by several db by changing a config file.
