A DAC converts digital audio information into an analogue audio signal. The digital signal is made up of a series of 0s and 1s. After the digital signal is converted, the Analogue Audio Signal can then be sent to a headphone amp or an amplifier. There are many DACs in the market. You can get portable DACs which cost less than £50 to some seriously advanced devices like the Chord Electronics Dave (approx £8000). I have opted for the ARCAM irDAC-II which has some impressive specifications. Check out my video

Had this TV since Nov 2016. Spent ages deciding which one to get at the time....it was a choice between OLED (LG) and Quantum Dot technology (SAMSUNG). Both had their plusses but the picture looked more vivid and vibrant when watching HDR with the SAMSUNG ( yes made Currys demo HDR for me with both TVs...). In fact was at Currys long enough to get a parking fine which later got recinded thankfully. All I can say is that the TV picture is great, I mainly use it for NETFLIX but the rest of the family use it for all sorts. With the promised HLG via firmware update it seems to be a good choice. Oh by the way you get a 10 year screen burnout with this TV (no similar option with the LG).
Huge strides have been made since the invention of the gramaphone in 1877 by Thomas Edison. We now enjoy hi-res sound. Many devices are capable of playing sound in hi-res 24 bit audio. HiRes Sound is slowly becoming the standard for many audiophiles. No longer are mp3 files good enough for the audio connoisseur. 24-bit/96kHz or 24-bit/192kHz files provide us with the studio sound quality as that the musicians intended. High-resolution audio files come in many flavours. Hi Res audio usually are sampled using a high frequency (96kHz or 192kHz at 24-bit). Other frequencies are also used. Analogue sound waves are converted into digital. Sampling frequency is the number of times samples are taken per second. The audio on a normal CD is 16-bit 44.1Khz Stereo PCM audio 24bit/96kHz (3.2x more data transmitted than CD) 24bit/192kHz(6.5x more data transmitted than CD).
