Are Preamplifier’s Relevant Today or just a Hinderance with Digital Playback ?

+1,00000,000 very clearly said and to the point. clearthink .

I tend to over elaborate too much with technical reasons and it confuses some.

Always best to use as much as possible all of the sources output, for reasons of noise/hum/distortion/colorations regardless of what it is, even phono.

You don’t floor the accelerator on a super car (the source), yet keep your foot on the brake (the preamp) to get to the destination ( the power amp)

it takes a heck of a DAC to have an analog section capable of robust drive and dynamics that a good preamp brings to the table-

Just about any good dac these days has an output stage equal to or even better than preamps especially tube preamps.
And you don't need anymore gain, we have more than enough in today's sources, use all the gain the source has, don't shunt it to ground, then make it back up again along with more noise and distortion added by a preamps gain stage.

Everything being a good match eg: impedance matched and also the digital domain volume control is not below 70% (so it "bit strips") then direct sounds just like what the the source is giving out, if it’s good or bad. Unless you want/need to color it with a active preamp.

If you can’t use your digital volume control at 70% or above because it too loud, then use a $49 Sys passive between it and the power amp to preset the level so then you can use the digital volume at 70% or higher.

Remember what Nelson Pass says about passive preamps

Nelson Pass,
"We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.
Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up.
Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control.
What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection.
And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp."
