DNA (Donald North Audio) Headphone Amp

[Beefy]

The benefit to slew rate from balanced drive comes from the ACTIVE stages. In the ZDT, the tubes are all run single ended

As I understand it, fully balanced SS amps can have much better stereo separation, because the grounds aren't connected.

Is it the same for a single ended output stage run through a transformer? Or are they still connected before the transformer?

Is this amp powerful enough to drive orthodynamic phones?

[mypasswordis]

That's one hardcore power supply right there

Is this amp powerful enough to drive orthodynamic phones?

My balanced Sonett didn't manage to drive my HE-5. Just not enough power (both voltage and current).

The digger up of old threads most certainly gets the shovel.

Sorry about the thread bump but I'm considering buying this amp. It's been around for a while now. Any thoughts (about the amp)?

[jp11801]

it's alright but if it were me I'd be saving my pennies for a EC ZD. The DNA sounded flat and somewhat boring to me.

Is there not enough in this thread and Headfi to answer that for you?

[yazz flute]

Obviously not. I was just wondering whether anyone here had some first hand experience with this amp by now and what they thought of it. Hence the thread bump. And yes, I've scoured the other place as well.
