Right now I'm trying to find a good DAC for my setup. I've got a TCL 49S305 Roku Smart TV with Digital Optical Audio Output that I want to pipe into my Technics SA-202 receiver, which in turn will be connected to a pair of Boston Acoustics T830s. Since the Technics does not have Digital Optical Input, then obviously I need a DAC. What's not so obvious to me is how much I should pay for one. Do I need a cheap, $5.99 Portta N3CDTAP? Do I need a pricey $1,850 BorderPatrol DAC? Somehow, I suspect the answer lies somewhere in the middle. Basically, I just don't want my DAC to be the weakest link in my audio chain. I'll be using my TV to watch Blu-ray movies and to stream FLAC music files via the Plex app. And I want the audio to sound as good as possible, given the other equipment I'm using. What would you recommend?
