Guest Posted February 8, 2018 Share Posted February 8, 2018 I know there are still plenty of people who don't know exactly what Computer Audio is and what its benefits are so I created this Primer for Computer Audio. There are also links for DIY with parts lists for exactly what is needed etc. Enjoy. Computer Audio Link to comment

It’s not useful. I saw that the topic was being ignored — now it won’t be. I’m just trying to be truthful while not being overly aggressive. Link to comment

botrytis Posted February 8, 2018 Share Posted February 8, 2018 It was a decent basic primer. Nothing wrong with that at all.

beerandmusic Posted February 8, 2018 Share Posted February 8, 2018 I have come to the understanding that everyone that has taken the time to write their first post is a self-proclaimed expert by then...but this is great for those first visiting (smile). Link to comment

GUTB Posted April 28, 2018 Share Posted April 28, 2018 I’d say the content updates make it more useful. I just wish there was something that could distill advanced CA knowledge buried in long threads like power supplies, grounding, isolation, filtering, etc. Link to comment

audiobomber Posted April 29, 2018 Share Posted April 29, 2018 This is useful info for someone who wants to get started with computer audio. Adding reams of info would just complicate and intimidate a newbie. Dynobot, you should add more hardware suggestions to the Client/Server section, e.g. Sonore, SOtM, Auralic. Main System: QNAP TS-451+ NAS > Silent Angel Bonn N8 > Sonore opticalModule Deluxe v2 > Corning SMF with Finisar FTLF1318P3BTL SFPs > Uptone EtherREGEN > exaSound PlayPoint and e32 Mk-II DAC > Meitner MTR-101 Plus monoblocks > Bamberg S5-MTM sealed standmount speakers. Crown XLi 1500 powering AV123 Rocket UFW10 stereo subwoofers Upgraded power on all switches, renderer and DAC. Link to comment

I've never tried those so I really can't endorse them. I'm more of a DIY guy vs. Off-the-shelf...not to say one way is better than the other. But for me this is a hobby so I like more hands on. I would recommend this though...at $119 it would be a great Music Server. https://www.amazon.com/gp/product/B01N3RO6X5/ref=ox_sc_sfl_title_8?ie=UTF8&psc=1&smid=A1UAUN9AXXYBEH Link to comment

Take your time and read the Setting up ALSA and Fine tuning page as well as the page with Dietpi. Both of those pages have references to go along with explanations on the tweaks. Link to comment
