Hi and thanks for taking the time to read this post.
I am thinking of upgrading my quad 405-2 with new net-audio modules, unfortunatly the supplier states the minium impedance must be 3 ohms which my speakers are probably lower, is there any way to add a few ohms onto the amp module thereby keeping it safe. Obviously inserting resistors into the speakers is useless as they add resistance not impedance.
Also i picked up a nice dac and am thinking of upgrading the opamp from a opa2604ap to a opa827 x2, is this a wise move as my friend told me the opa2604 is such a good opamp that i will probably not hear an improvement, next to the opa2604 on the circuit board of the dac there is a chip labelled tl0722cp does anyone know what the best upgrade for this would be.
Many thanks in advance. John.
