Will I improve HT audio with an external DAC?

Any significant benefits to buying a dac for my Panasonic DMP-BDT 210 blu ray player? I have a Creek Destiny amp and no plans to go multichannel yet. I was looking at the m1 with the idea of connecting my laptop too.
Not sure I understand the question.

What Pre do you have the Creek Destiny amp connected to?

If you are not interested in multichannel then do you even have "HT" now?
If you are doing blue ray only, a regular dac does not seem to make sense. If you are doing a lot of music cds, then yes, absolutely.
Erikt, the Creek Destiny is an integrated amp, so a preamp is irrelevant.
Arni, if cd's will sound better with a dac then why wouldn't the audio from blu-rays or netflix improve? BTW I use the Panasonic for both.
It will, but you will not be able to reap the benefits from TrueHD and DTS-HD, hence the sound from the player´s analog out might rival the dac on HD recordings.
