The Monarchy piece would probably warm up and smooth out your Sony DVD and Bryston power amp combo. With the single source that you have, i see no problem with this. My only suggestion is that i would try using the digital coaxial output ( if you dvd has one ) and the optical output to see which you like better. Theory says that coax should be better due to less circuitry involved, but you'll never know what you like better unless you try them both. Sean
