i have a nuforce dda-100 for my stereo w/ bookshelves, i really like the idea behind direct-digital. keeping your signal digital until the very last segment of the circuit, and using PWM to convert sounds like a great idea. it also allows for a much lower noise floor than ive found with a tube-based system. i was looking to simplify my setup and go back to solid state technology, so long as it implements direct-digital technology. at the moment, it seems like just nuforce and NAD have that segment of the market on lockdown. is there anywhere i should be looking?

If you have hard to drive headphones you can hook them up to the DDA-100 or a Wadia 151 through the speaker outputs.

It's a very good question.
 
Even the Denon PMA50 all-digital amp has an op-amp for the headphones.
 
Is this tapped off the speaker outs I wonder, or running off its own DAC?
 
Presumably a CSR or Nuforce chip could drive a headphone amp - why shouldn't it?

We have had this tech for a long time, and most of us just call it Class-D amplifier instead of 'direct digital'. It is also not an exclusive tech as you can buy chip from TI that does just that. For example: http://www.ti.com/lit/ds/symlink/tas5100.pdf
