I don’t know a doggone thing about DAC’s, however
It is VERY HIGHLY UNLIKELY that any DAC signal is close to or exceeds 2.5 Volt
a bit of history, in round numbers: The standard output of tuners and ceramic phono to mono amps was 1 volt prior to Magnetic Cartridges.
pre-amps were introduced to get the smaller magnetic signals up to 1 volt, then to the original amps. Mono was 1 amp, 1 good speaker. Then, Stereo, ADDED a second amp and ADDED a second speaker, dual mono, and the subsequent continued love of mono amps.
Next, stereo preamps, stereo amps. Still essentially based on 1 volt to the amp.
Then variations, stronger signal strengths. Some CD players, especially ones with built-in volume controls signals went as high as 2 volt. You could skip the pre-amp, go straight to the amp.
McIntosh amps have 2 position switches: .75 volt, and default 2.5 volt.
Thus, the world is based on ... no stronger than 2.5 volt,
Thus, VERY HIGHLY UNLIKELY your DAC sends more than 2.5 volt.
As I said, round numbers, my point is to give you the confidence to try it.
Or, buy an in-expensive multi-meter and measure it.
btw, My Tandberg Receiver includes a potentiometer at one of it’s rear inputs, so that two phono inputs (different cartridge strengths) could be ’equalized’ to the innards thus equal volume to the speakers.
McIntosh Vintage Preamps have ’trim’ controls (potentiometers, on the top, near the front) (more easily accessed, just slide the preamp forward about 2"), to ’equalize' several inputs, my SS C28 had and my vintage mx110z tube preamp ’trims’ three inputs: two phono inputs, and 1 aux input.
If you love your equipment, and found a signal strength mismatch, you could add a potentiometer in-line.
