Mine already had the latest update since I bought it used.

I have not. Didn't know it existed. Will do that today.

I've paired the hdv820 with the sennheiser 800s headphones. Its such a huge step up from the psaudiosprout100. I mostly use it for Netflix. The scenes feel alive. The clarity and Soundstage contribute so much that I understand and feel what is happening in the scenes even if my eyes closed.

Learned I was an audiophile not too long ago and I am hoping to learn how to build an amazing headphone system around Chord gear so I can make full use of the m scaler.
