I am a bit embarrassed to say that I have never had a stand-alone DAC, and never felt the need for one. With the reality of streaming music and playing music that is on my phone growing in my routine, I am beginning to see the need. Going back to the late '80s, I have always relied on the built-in DAC's of CD players, etc. So, I am much more of a budget-fi than a hi-fi guy as in, I really don't want to spend $200. I'd prefer to stay under 100 up to around 150. I watched Johnny Darko's intro to DAC review video and I know he likes the Schiit Modi3 for that price range. I have just become aware of the SMSL Sanskrit 10th for just under 100. The way my HT is set up, I am running the HDMI to the TV and running the optical out from the TV to the Rotel Pre-Amp. My Blue-ray doubles as my CD player, which runs to the TV, or I have a Denon 2930 for multichannel music that I use for SACD and can use as a CD player running directly to the pre-amp So, for the price range, would the DAC only be a benefit from my phone to the pre-amp or is it something I would want to run the optical into from the TV and then into the pre-amp? Secondly, the best sound and reliability for the dollar recommendations would be greatly appreciated.
