This discussion poses a question in regards to the Preamp-Amp gain/volume control. Should I run the amps [Mcintosh MC 60s] full out with the gain controls available on each amp and use a lesser level of volume on my preamp,[Zesto Leto tube pre]? Does trimming the gain on the amps give me less headroom when listening at higher volumes?
The output impedance of the Preamp is relatively low 150-250 Ohms to the input impedance of the amps which is 500K ohms. The preamp has two settings for gain, set internally, of 3 db and 12 db and came to me set at 3 db. I have very efficient speakers so the headroom of the amp and pre is sufficient either way. I rarely have the volume on the pre at 12, more at 10-11 max with the gain on the amps maxed out.
I ask this because I do fight brightness a bit and would like to optimally control the tone of the system towards a bit more mellow direction.
