I was wondering why my ah-d7000's sounded so good from the headphone out of my hk3490 so I emailed HK to ask what kind of amp it has. The response was....
[size=x-small]"Thank you for your inquiry. For this model, the headphone jack is powered off the main amps, but has a 270 ohm resistor in between the speaker outputs and headphone output. [size=x-small]The power amplifier in this model is discrete circuitry and the preamp is op-amp based. [/size][/size]

Unless I'm not understanding right the headphone jack has direct access to 120 watts rms per channel with a 270 ohm resistor in between putting it somewhere between 10-15 watts available for 32 ohm phones according to a sloppy math equation. The processor seems to do a fine job as well with a toslink straight from my motherboard. I'm still making up my mind but I think my essence stx just lost it's purpose in life. Let me know if I'm full of crap please.
