Thought you might like that. I don’t have experience with Audio Dynamics but they seem legitimate. AudioX sells that brand and some shops in my area do too. I think it has the most desirable features given the price point and I think the same build house that builds the Dayton 408 makes this too. I purchased one of the very first Dayton 408 DSP’s that came out I think two years ago now and it’s still going strong and gets used every day in the wife’s daily driver.That ADDSP46 looks nice for the price; I've never heard of Audio Dynamics, are they a good brand? It looks like it has a slightly higher output voltage than the MiniDSP, and all I really need are four inputs. My civic only has four output channels anyways, so it would work well for my setup. Thank you for the link!
