Volume matched inputs on a preamp?

I'm not quite sure how to ask this - but I'm wondering if there are any preamps that allow you to set the volume by the input so you can volume-match one input to the others.  So many DACs have different output levels, it's hard to compare them.  If you could set the gain by each input to volume match all the inputs - that would be a lot of fun.  Yes, I send digital signals from a single source to different DACs and like to switch between them to see how they may differ.  Tube or solid state doesn't matter, but I'm guessing it'd be easier with a solid state preamp.

Multiple google searches for key words did not turn anything up.  

Thanks!

@marlin38 Hi, What you're looking for is a pre-amp with adjustable gain on each input. I believe some Pass Labs pre-amps had this feature.

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.

More to discover
