thanks guys

I like you Chris. Thanks for the laugh. It is nice to find someone else that has a warped sense of humor. Analog Realm...I really need to watch GoT. : ) Phasor diagrams ARE really illustrative though, don't you think? We even use those in climate science and atmospheric dynamics. 

Hey I like your sense of humour too!
Us Power Engineers use phasor diagrams quite a bit. They really help us out.
If you haven't seen GoT then the Analog Realm is just West of Mordor. Mordor is the Digital Realm.
I must admit that I have no idea what Mapping Electron Flow with PDEs is?
Partial Differential Equations?:mad:

The Leck probably has an output impedance of 100 Ohms!

 
According to InnerFidelity, it's 0.4 Ohm...

So the plot thickens...
 
Though I must admit, the Leck is looking mighty tempting considering the price, and also the fact that they're offering it with OPA627, which is my personal favorite.

Then my next guess is that it is very limited in current output, hence the low power output into low impedance loads!

i have dt770/250 is it a good pair with E12?

If your question is:

does the E12 have enough power to drive 250 Ohm Beyer DT770 then the answer is yes!
Should not be a problem.

no it's not the power, i mean the sound, i want to tame the high and add the bass, and more body to the mid, can E12 do that?

Yep. It'll do exactly that.

How does everyone think the E12 would perform with the HE-500's? I predict that I will want to travel with the 500's and NOT bring my entire setup....I've heard the E12 is ridiculously powerful

 

[Bill-P]

Actually, I won't even "think" about that, because I have plugged the HE-500 into E12 for real.
 
If you plan on traveling with HE-500, then it's better to lug along an O2.

I just received the E12 a couple of days ago and so far I'm pleased.  Overall, the E12 seems to be more linear (flatter sound) than the E11, which I prefer.  My only question is why the E11 (around 5 on volume knob) would be as loud as the E12 (at almost max volume).  Both are in the "normal" position.  However, when the E12 is kicked into high gain, it's no contest.  I didn't get to read the whole thread, so apologies if this was already discussed.

I'll pass on the O2...here too many mixed opinions about it! And I'd rather not buy another amp just for the 500's. I'm a "one amp" kind of guy! I'll just have to see how the e12 fairs...and I'll something good to compare it to  

 

[Bill-P]

To be fair, I don't think either the O2 or E12 is a good match for the HE-500. You may want to get a desktop amp if you plan to get the most out of the HE-500. It's such a power hog because its sensitivity is so low.

 

[jiggahwhat]

I'm sure you could adequately run the HE-500s out of either amp but you would need a desktop amp to get the most out of the sound. Given you probably won't be moving around with the HE-500s much, it doesn't really make sense to go with the E12s.
