Total System Gain Question


I am considering an amp with 25dB of gain and 575mV input sensitivity for rated minimum output, and considering a preamp with 18dB of gain. So total system gain would be 43dB. My speakers are 88dB efficient.

Is too much gain for a 2V line level DAC source? I don’t know what the input sensitivity of the preamp is. I worry I’ll be stuck in the bottom (non-linear) portion of the volume pot due to the total gain ...

I don’t have a feel for this since I’d been using an integrated amp forever.

If your concerns have anything to do with the previous thread on Gain wars there is no need to worry.  2V output from the source is just about industry standard. Actually those specs you listed look common and should mix and match easily.  Some high end designs can have some pretty unusual specs and can be more difficult to mate, but really isn't an issue for the vast majority of gear.
