Default A/V receiver (Dolby Headphone) + DAC

Would it be a "good" sollution to use a (Stello da220 mk2) DAC with an A/V Receiver (Dolby Headphone) while playing Dolby Digital sound from a dvd movie? Would the DAC enhance the sonics (sound) or is a DAC only useful for stereo music playback?"

Since you can't use bit stream It was only be processed as PII.. I notice a difference with my DAC1 DH combo with movies & games..But on music I can really tell the difference.

I have just read somewhere that: "if you play dolby digital, the AVR acts as a DAC in this case. Stello wouldn't enhance anything because it is not used in the first place."

I can't test the Stello dac yet, because it hasn't been delivered yet. I am just trying to assume it would enhance the sound.

Fortunately, my AVR has a 24-bit 192mHz dac.
"Why does your 'digital to analogue converter' (DAC) matter so much?
The quality of the DAC in your AV Receiver plays a big part in the quality of sound you'll hear. As your AV Receiver receives digital sound information from your DVD player, your DAC converts that information into analogue sound signals which are passed on to the speakers. As a general rule of thumb, look for 24-bit 192MHz DACs if you want a cinema quality (or better) home theatre experience. Lower numbers (e.g. 12-bit 96MHz) mean lower quality sound."
I am still trying to find out if my main dac (Stello) will enhance the sound even more.

Nope.

Just hook up digital output directly to your AVR.

Leave your Stello for Stereo music.

Your AVR will decode the movies audio and use its own DAC, so there's no more digital signal to be processed.

My alac music tracks are stored on my pc hard disk, my pc is connected to a squeezebox duet through ethernet (which has a very nice remote). So to bypass the Duet's dac, I should connect the Stello dac with the Duet through the optical in/out. Right?

I hope I will bypass some built-in dac's by using digital connection?
Would this be the optimal order to connect my audio equipment?

1) Squeezbox Duet (source) (bypass Duet dac),
(1 and 2 are linked to each other via optical cable)
2) preamp HeadRoom Home Balanced (bypass preamp dac),
(2 and 3 are connected with optical cable)
3) Stello MKII dac (finally use the best dac available in my audio inventory)
(3 and 4 are connected to each other via RCA interconnects)
4) amp Red Wine Audio Signature 30.2

I just found out that the HeadRoom (pre)amp has no digital out. So the correct order of connection becomes:
1) Squeezbox Duet (source) (bypass Duet dac),
(1 and 2 are linked to each other via optical cable)
2) Stello MKII dac (finally use the best dac available in my audio inventory)
(2 and 3 are connected via XLR balanced interconnects)
3) preamp HeadRoom Home Balanced (digital stream has been converted to analog by the Stello dac, thus bypassing preamp's dac),
(3 and 4 are connected to each other via RCA interconnects)
4) amp Red Wine Audio Signature 30.2
