When using a fiber optic HDMI cable, you also don’t need to worry about latency or jitters over long distances.
These miniature connectors allow you to connect with smaller devices like phones, tablets, and monitors with smaller port options. so assuming that the dac is equal in quality i would convert at the receiver. I could be mistaken, but my impression is that analog signals, especially unbalanced, low level signals, are susceptible to noise whereas digital signals, especially optical, are not. So you want to keep your analog signal path as short as possible. On paper, HDMI eARC also makes the handshake between compatible devices much smoother and negates the need to activate HDMI CEC (which doesn’t always work properly) - so operating multiple products shouldn’t require any extra steps to get things up and running.

Optical HDMI Cable, also called HDMI AOC （ Active Optical Cable ), is a kind of HDMI cable that uses optical fiber to achieve HDMI definition signal transmission and its photoelectric conversion lines are integrated at the interface. Optical fiber is a transmission medium used to transmit optical signals; Unlike the conventional copper HDMI cables, optical HDMI cables adopt optical fiber as a transmission medium and features an HDMI interface at both ends. Compared to the typical HDMI cables, fiber optic HDMI cables can send signals over a longer distance without facing electromagnetic and radio frequency interference. Also, signal loss is significantly reduced when using fiber optic cables. This cladding is purposefully made with a lower refractive index than the fiber optic cables, which is how total internal reflection is made possible. Manufacturers usually do this by adding some impurities to the cladding. High-Speed Automotive HDMI Cable: This type supports the same features as High-Speed HDMI cables but is optimized for the automotive environment. Unlike optical cables, copper-based HDMI cables have issues with interference and length. The main issue here is going to be the length. If you want to transfer 4K video over a copper HDMI, you can only reach around 30 ft. before you start having issues (more on that in our HDMI troubleshooting guide).
As part of the process, you should consider enabling HDMI CEC (Consumer Electronics Control), so you can turn your TV on and control the volume on your soundbar or amp without the need for multiple remotes. A word of warning, though: turning HDMI CEC on can have some unwanted AV side effects, so you might want to experiment first.
Bottom line
Or perhaps your smart TV is using a built-in video app such as Netflix, Disney+ or Prime Video. Either way, you don’t want to use your TV’s speakers for audio – you’d rather hear everything played through a soundbar or AV receiver instead. If better to use the panasonic dac, then should I go ordinary analogue interconnects, or the balanced pin cables? why? You'll find HDMI inputs and outputs a firm fixture on the best TVs, Blu-ray players, AV receivers and, increasingly, soundbars. An entry-level cable like the AudioQuest Pearl HDMI will suit a wide range of systems. Premium High-Speed HDMI Cable: This cable type is designed for reliable transfer of 4K/UltraHD resolution video, including4K/60 Hz, HDR, and expanded color range. Cable bandwidth support is 18 Gbps and is optimized for HDMI versions 2.0/a/b.
