    Roon Server on NAS or Standalone

    Hey all, I want to spin up a Roon Server, and I'm looking to figure out how much CPU power I'm going to need as I heard Room is pretty CPU intensive. I currently have a beefy NAS that runs Plex, and a few docker containers and has 108TB of storage drives on it. It would be ideal to Spin up a...

    RPi4 + Pi2AES alternative or off the shelf unit?

    I'm looking to set up a streamer in my living room in the not-so-distant future and have been looking into my options.

    Line Array Speakers : Modular, Expandable, Out-of-the-Box Design for in-home use

    That title… Sounds impossible, right? Possible, and sounds right.

    JBL L82/L100-inspired bookshelves

I also found out that you can purchase the grilles, or a fairly good clone of the foam, for a reasonable amount of money. So, I’m looking to make something in the same dimensions as...

    EAC has posted DIY speakers, Samba and Overnight Sensation measurements

    The P.E. Dayton Audio DIY kits did not fair all that well. Has anyone here heard them? I have not heard either set. The Samba RS drivers are still obviously extremely good reasonably priced drive units. The cabinet is solid but that crossover is just really short of a good design. What gives...

    DIY Fet microphone preamp

    There are a few designs posted over the internet (4 FETs in line). Is there a preferred one given the components availability in 2022? Or "just buy the Fethead from Amazon" is the way to go?

    3D Printed Aurora Borealis style headphones
