I've done business with Micca.  Flawless transaction.  I recommend them.

Same experience here.

Next week we'll discuss real power vs. apparent power WRT to reactive power, explain power factor and finsih off with a technical dialogue regarding reactive phase angles and back EMF.

On second thought, let's not bother.

Can anyone suggest a good material for a light metallic hat to block the alien radio waves manipulating my thought patterns?

Agree, mate. I didn't think it would be appropriate to to talk about 0 phase angles and the what not. (e.g. "real" part being resistance and complex part being reactance, with impedance being the magnitude of that vector.) Or perhaps we could map the electron flow using PDEs, either analytical or numerical. My point holds. Anyone with a nominal knowledge of electronics will tell you that.
 
However, this was superseded by the sensitivity discussion.

Might be easier if we use P.U. calculations?
Should we use magnitude and phase or complex algebra?
Phasor diagrams?
 
Note: phasors must be set to "Stun".
 
I will leave you in charge of mapping electron flow using PDEs. I'm a power engineer.
 
BTW, the Analog Realm is where Kaleesi is from in "Game Of Thrones".
The Iron Throne is located in the Digital Realm.

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.

anyone tried the dt770 250 ohm with these? also which portable dac should i get?

I have dt990 250 Ohm with these, it seems like the treble has been tamed a bit(which I like). I also have the E17, I haven't had a chance to use the Dac of the E17 will try tomorrow when the adapter gets here.

Can this amp drive 250ohm beyers, I had the Leckerton MKII and while it drove them I didn't think it drove them with authority. Can anyone tell me if the e12 is more powerful than the Leckerton, here are the leckertons specs:
 

1. Max output power (1% THD):
   1. 30 mW into 16 ohms
   2. 55 mW into 32 ohms
   3. 110 mW into 100 ohms
   4. 55 mW into 300 ohms
2. THD+N at 1 kHz (optical input, 20 Hz to 80 kHz bandwidth, no weighting):
   1. 0.0035%, 1 mW into 16 ohms
   2. 0.0060%, 1 mW into 32 ohms
   3. 0.0022%, 1 mW into 100 ohms
   4. 0.0035%, 1 mW into 300 ohms

Output Power

>880mW@32Ω

 

THD

<0.005%

 
it trumps the leckerton in terms of power
 
that spec sheet is weird though, does it have variable gain or something

 

[gerald410]

Imho they most certainly can drive 250 Ohm Beyers or at least they're able to drive mine
Ps I should've never removed my avatar now i can't add one

I just picked up an E17, but now i've got some second thoughts after this thread. But I like the eq on the E17. hmmm..decisions decisions....

I like the sound using the E17, arguably better that the E12 right now. I attribute that to the absence of an external DAC when using the E12 right now.

The Leck probably has an output impedance of 100 Ohms!
