Volume matched inputs on a preamp?

Ditch those DACs, Go Vinyl, go Vintage

My McIntosh preamps (prior SS C28, current Tube mx110z) have 3 adjustable inputs. But only one line level, AUX, the others are Phono 1 and Phono 2, both have RIAA eq in their circuit.

Tandberg TR-2080 let me adjust 2 phonos and a tape input I think.

In all cases, it involves 'extra' potentiometers in the circuit, not a purist favorite. Option to use for comparison, and then bypass filters, tone controls became popular to have but eliminate in-line controls, ascertain if you can hear any difference. Several pieces I have owned with 'bypass', or 'video circuits out' or 'display lighting' out, I don't hear any difference.

My old Levinson No. 32 allowed gain levels to be set for each input.  It even allowed other settings, such as left-right balance on phono input to be programmed apart from the system balance (most cartridges do not have identical channel output).  I believe the BAT and VTL linestages also have this feature.

The Aesthetix Pallene lets you do just that 

I am not sure about the newer models, but I know BAT's older preamps allowed you to set relative volume level for each input.

My Audia Flight integrated allows me to set the gain and balance for each input.
