Also,

Anyone had good memories from Christmas?! DD HIFI surely wanted to give us long lasting impressions with their IEMs, packaged with deer.

I regret not talking with him longer when I had the opportunity.

They use IEEE wireless protocols. The protocol used depends on the type of wireless used but will be a subset of the 802.11 protocol. The wireless protocols are a subset of the IEEE 802 LAN/MAN standard. http://www.ieee802.org/ https://en.wikipedia.org/wiki/IEEE_802

To answer your question. Bluetooth and Wireless do not use a codec directly. The codec data is transferred in a packetized form from one node (device) to another. For instance, a node would be your dap, and your Bluetooth receiver on your headphones or your bluetooth dac would be a node too. The entire IEEE 802 standard is a way to transfer data from one node to another, in a packetized format, and keep that data intact. It's very complicated and takes many years, days, hours of studying to understand depending on your savvy and technical prowess. I'll put links and pictures below for info on the 802 standard so you can study it if you want.

Thanks for the links (although I haven't looked at them yet).
.
Since Wi-Fi has a lot more bandwidth than Bluetooth, I was wondering if the Roku Remote (with a Wi-Fi connection) should have higher audio quality than a Bluetooth earphone link (taking into account that the Roku is a standard embedded Linux 16-Bit / 48-KHz device)?
.
Something new that Roku can do, is stream audio to your phone, that's on the same local network as the Roku unit.

So no takers for the linsoul gift card? :wink:

Also selling my DM6 and potentially other gear...

My last order from Linsoul took so long that it'll be a while before I buy from them again. Until the next thing I can only get there....lol. GLWS on the DM6 and other gear.

Got another show to see tonight: Eric Johnson. Loved his guitar playing, smooth voice. Should be a great show.
