    Turning an Amazon Fire TV Stick (2nd gen) into a media player with DSP

    So after looking into some depth at room correction SW, I wanted to see how to implement DSP into my system. Initially I looked at various of-the-shelf solutions, but in the end decided to see if I can work something out myself - ultimately audio DSP is just a bit of computing power combined...

    Internet Router to DSP to streamer/DAC

    I have an integrated streamer/DAC. I want to be able to use a DSP system for room correction before the signal gets to my streamer/DAC, hopefully directly from my router. I know that ROON, which I'm using, has DSP capability, but it looks fair hard to get properly setup. Are there any devices...

    Dac - Dsp - Crossover

    Hi, I'm new to this forum and hope you forgive my mistakes. I'm a old audiophile who wants to upgrade his (now) simple system (Oppo BD95 + Pass Labs amp + Magnepan MG 3.3) to multi amping. As everybody says Magnepans should sound better in multiamping (maybe all of the loudspeakers do) and I...

    Active Designs & Their Favorability

    Why are active speaker designs so favorable? Should space be available, why wouldn't you want to have the dac, dsp, and amplification devices be independent of the speaker? This allows for easy upgrades if so desired, as well as more control over the hardware in general; you'll likely choose...
