Yep, I've got BOTH! There is NO comparison. The SX350 wipes up the floor with the
dna. The DNA with it's 4 volt minimum, means, that any sub ohm firing, is NOT EVEN possible. Or, rather, any serious sub ohm firing. It will go down to .6 ohms THEORETICALLY. I've never been able to get mine to fire that low. But, different units, who knows. My SX-350, I have fired down to .2 ohms. Acutally, is was a hair over, like .244 or some crap. It indicated .2. I was using Sand Ballast resistors, in Parallel, to give me the resistance I wanted, and the power handling capability I needed.
Also, the new software upgrade should be out on the 1st of May. That, will bump the output power up to 35 watts. On the SX350 that is. Ah firmware upgrades are such a lovely thing! Also, A NICE way to fix little niggles that always seem to creep in. It can be updated via the mini USB that you use to charge with. The Mini USB, DOES have more than 2 pins, the Pos. and Neg. for the charging, the other pins, serve nicely as signal + and - for data to the firmware. Blue, and White wires. Just for the sake of accuracy ;-)
Well, that's my Un-biased comparison

The DNA30d SUX in comparison. But, to be fair, the DNA30d was a real smoker, In it's day.
I've got a bunch of the DNA30d's, I'd have to sell them for a fortune, just to break even. Ha. Even have one new, but slightly older DNA20d.
