What would be the simplest option to insert between digital outputs and an amp, that’s relatively cheap? It’s just TV and occasional music into a couple LS50s in my living room. The Yamaha receiver I’ve got has their proprietary room correction, but it’s...meh, so I’m curious about exploring other options. Considering I’m nifty at building electronics & have a basic understanding of programming, I‘d be fine with less plug & play options. The miniDSP stuff looks great, but are there other decent options at or under the cost of one of their boxes with Dirac?
