Hi. I use a computer as my source with a miniDSP OpenDRC-DI (seen here
https://www.minidsp.com/products/opendr ... opendrc-di). The miniDSP is positioned between my USB/Coax converter and my DAC.
I bought the MiniDSP initially for digital IIR filters to help tame the frequency response of my 8" full range Tang Band drivers. Since then I've switched to vintage Altec components with Altec XOs. I plan to use the FIR filters of the Open DRC-DI to help with phase correction. I recently downloaded Rephase for this but haven't had time to implement it yet.
https://sourceforge.net/projects/rephase/I also own a MiniDSP 2x4 which I've installed in my car to provide XO to my front stage components. It's positioned between my headunit and my 4 channel amplifier to privide XO and time alignment / delay. I installed it only a few weeks ago but inital results are quite promising!
Linkwitz labs has several speaker designs utilizing the miniDSP.
