DAC DIRECT IN TO AMPLIFIER OR TO PREAMPLIFIER


For the longest time, I believed that the best preamplifier is no preamplifier.  Eliminating a component from the audio chain would yield less distortion & greater purity.

Recently, I have had reason to re-think my logic on the matter - and I am (I think) changing my mind.  Better said, assuming that the preamplifier in the component you are using (in my case, a DAC) can produce 95% or greater quality sound compared to the preamplifier component, then no preamplifier is the best option.  The 5% represents the (estimated) loss of fidelity in adding another set of interconnects.

That said, most DACs do not have an outstanding preamplifier built in.  I think most have average passive attenuators, and the better DACs have active preamplifiers that are very good - but not as good as a quality preamplifier.

What are your thoughts?

Every situation is a bit unique, but preamp outputs tend to be better suited for driving the impedance of any given amp than a DAC output.  That's not saying that aren't acceptable matches between some DACs and some amps, but it's primarily would preamps are made to do.  Then there's convenience of input selection, phono stage, balance, tone controls, etc.  

This just seems to be one of those very important decisions in audio that needs to be made by trying both in your system as there are just too many variables to make a confident prediction one way or the other.  Best of luck in finding the right option for your tastes/system. 

This is a great, hotly contested question. I have no opinion really. I have a Bel Canto Black EX pre/DAC and a PS Audio DAC to amp. I have considered buying a PS Audio preamp multiple times but never pulled the trigger. Paul McGowan recommends a preamp in the system.

a great preamp is key to a great sounding system...it is the heart and soul. 

I have tried a DAC directly to an amplifier, sound horrible in my system.  I hope others happy without a preamp, didn't work for me.

My DAC has tubes and I still have a Pre-Amp. Everything sounds much better with a Pre-Amp.
