Let me state this back to you to make sure I understand,the output of the cd player is proportional to the signal from the disc, with a 2v max for the cannon, being the signal with the most amplitude.
I checked again the input specs of my receiver(sansui 317)and the service manual reads aux, tape play 150mv/47kilo ohms, so this is the minimum signal to get full response.
I listening to a pair of utah coaxes in a ported box.
3 ticks up on my volume control (8:00) is too loud. I was thinking my input is too high, apparently this is not correct.
Do I just need less efficent speakers?
thanks
Follow Ups:
Back in the day of your Sanusi, most cd players came with a variable out. Now the cd players or dvd blu ray just have a direct out of 2 volts. Conversely today's amps today have around 300 mv input sensitivity. So you have more steps on your volume control. It doesn't help your specific case, except for an explanation.

Well, yes, less efficient speakers might help-
you have created the perfect storm- in that you are using very efficient speakers, so you do not need much gain to drive them to pleasant levels-
and yes, the Sansui has a very low input sensitivity -
You have a couple of choices-
You can live with letting the amp loaf along and enjoy unparalleled headroom (because you are not taxing the amp)
Or you can add some resistors to reduce the output of the CDP and go to town-
I would leave it, and not crank up the Volume pot-
Happy Listening
thanks everyone, i have been sat at ease...
