Perhaps I have not read well enough, but here are my opinions.
Most people who use a Stereo for TV/Movie watching, run HDMI devices into the TV, then take the Optical Audio Out
of the TV and feed the amp/dac.
True today there are HDMI DACs that will extract the sound from an HDMI signal, but they are not doing much more than your TV is doing.
Next, has it been stated how much MONEY you are willing to spend on a DAC? Given the cost of the Yamaha AS1100 ($2499)
, you should be able to afford a pretty nice DAC. Schiit are pretty good, Chord, Cambridge,
and many others, but first you have to work out how much money you want to spend, and whether you have other uses for a DAC. For example if you get a DAC with USB-PC, you could make a direct connect to a Computer.
As you can see the Schiit's DAC span quite range, but depending on the features for a DAC in general, I would say the common price range is $200 to about $500, though of course, the do go up to many thousands.
Here is the Essence HDACC II-4K - $599 -
- 4xHDMI v2.0a Inputs x 1 HDMI v2.0a Output
- 32 Bit / 384K Sample Rate Audio Upsampling
- Supports HDR10 and Dolby Vision
- Supports 4K Video
Nothing wrong with that if that is the route you prefer.
And thought perhaps a bit too common for your system, you can buy a High Resolution DAC for as little as $25 on AMAZON.
Something like this doesn't seem out of the question for the system you seem to be planning -
1xOptical, 1xCoaxial, 1xUSB-PC
At the link above, there are a couple of MODI models, there is a drop down box for the versions - Modi-3 is $99, Modi Multibit is $249
Again, there is no shortage of straight forward DACs to choose from, you just need to set a Budget.
If you want to add Network Streaming to the system, then the Yamaha WXC-50 Network Streamer/Pre-Amp ($349)
does a good job at a pretty reasonable price -
Next above that would be the Bluesound Node-2i - $499 -
Probably next above that is the Cambridge CXN V2 Network Player - $899 -
It is worth noting that the Cambridge CXN
allows external access to its internal DACs, so it is both DAC and Streamer. 1xOptical, 1xCoaxial, and 1xUSB-PC in, and of course Network/LAN In.
Also, it has Pre-Amp capability. Many people us the Cambridge CXN as the Pre-Amp for a Power Amp, thought the pre-amp aspect is not mandatory; the output can be switched between Fixed and Variable Output.
There is a version of the Bluesound NODE
that has a built in CD Player/Ripper and a Hard Drive -
Bluesound Vault-2i - $1099 -
The hard drive would be able to hold THOUSANDS of Albums, not songs but ALBUMS.
OF course you can spend as high as $17,000 on a Streamer if you are so inclined. But that seem excess in the extreme.
There are several members of the UK AVForums.com
that have the Yamaha AS1100
and the AS2100
and the all seem very pleased with the amps.
So, you do likely need a DAC to go with the AS1100
, the underlying question is what type of DAC? Myself and many other are content to run HDMI to the TV, and take the Optical Audio Out and feed the Amp/DAC. However, HDMI DACs do exist and presumable to the job. That's really a personal decision. Perhaps ask yourself how many HDMI Devices do you have, and do those cables running up to the TV really create that much clutter?
But then ... that's just my opinion.
