Bill, agree with you. sorry, I was not willing to irritate you and your test of E12 was really interesting. Lets wait how many happy users E12 will get.
You know we are all different people with different ears and tastes. What I value however is when people share unbiased opinions and you did great job on this. I would NOT expect you to be BH lover and I fully understand people who love E12 better. my listen of E11 was poor result but I trust you and others who say E12 is better amp.
Yes, I forgot to mention why I bumped into E12 forum. I am considering second amp because my daughter will need one. So the idea is either I keep BH and buy something for my daughter or I upgrade to hi-endish amp and give BH to my daughter. She listened to my BH with her iPhone and iPod and she loved BH.
Oh no, I'm not irritated. I was only trying to understand your inquiry.
There's one thing I would like to admit, though: this review is not unbiased. I liked BH a lot (you can dig up my posts about BH somewhere within the BH thread if you need the story), but I came to like E12 as I listened to it through my headphones. After that first initial impression, I already had a bias in my mind that E12 was the best portable amp I had heard, and my initial ranking of E12 over O2 and C421 reflected that. That was my bias kicking in.
So I don't think you should take just my opinions on this matter. Maybe it's best if you purchase an E12 and try it out yourself. I'd also love to hear from other people's impressions regarding E12 vs BH, because I'm really not sure if I wrote all of that without letting my bias kick in.
I can tell you one thing for sure, though: C421 is indeed better than BH in every way. If you are having a hard time deciding on what to get, then I'd recommend C421 over E12, especially because you like BH so much.

Bill,
I am anticipating purchasing the E12 once the revised bass units are available in the US. Regarding there significant power, do you feel the E12 has an advantage even with lower impedance headphones since the amp can be run at lower levels without being "strained" and as a result will run more cleanly?
I think the sensitivity (efficiency) of the headphone needs to be taken into account as well. Some headphones have low impedance but also low sensitivity/efficiency (orthos like the Hifiman HE series or the LCD-2), and as a result, they require lots of power. In fact, when I tried E12 with those headphones at the recent meet, E12 was definitely bumping into its upper limits.
That was why O2 won out. O2 sounded effortless with those headphones, whereas E12 sounded like it could use a bit more power.
If you meant low impedance but high sensitivity headphones, though, then I think E12 should be fine. My ES10 is low impedance (~40) and high sensitivity, so E12 had ample juice for it.

In unrelated post i found a review of jds labs c421 and leckerton uha4, seems like a very tough call ... Wonder what Bill thinks about these two if he had leckerton. Of course i talk about slim version of leckerton. Actually funny if i buy one i will make cockroach race between that and BH, will be fun.
I haven't tried the Leckerton UHA-4, to be honest. But if I were to buy another portable amp, I think it'd be the Apex Glacier...
