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?

short answer is it depends... blanket generalizations not useful, specifics matter

Indeed. Which is why I point to specifics. An active preamp is required in many circumstances.

Until I heard my system with the Lumin X1 going straight into my amps, I would have thought a preamp to be essential.

The Lumin made the sound quality so pure and effortlessly that I will never go back to a preamp.

Unless you need a preamp because of the need for more inputs or switching capability, to me, the preamp just adds more circuitry, cables, footers etc. I prefer to keep it simple.

Only DAC direct to amp that was worth considering for me was the Lumin X1. It was almost as good as the volume  control on the Benchmark LA4. It has some gremlins at low volume, but still sounds good, and great in comparison to other DACs. The LA4 is perfect as a volume control.

My current 2 DACs do not do volume, a Schitt Yggi+ Less is More and the Benchmark DAC3B. I am going to get 1 more DAC and I do not think that has a volume, hopefully not.

I agree that blanket statements in high end audio can be problematic. But in this case, moderated by “in the majority of systems a high quality preamp” will improve the sound quality is fairly safe. Direct to amp typically produces a highly detailed but (typically described as) dead / lifeless sound. If you review the topic here on earlier posts you’ll see that 90+% have experienced this. Most folks that try it, go back to a preamp. I would recommend a high quality tube preamp. Some folks have done very careful component matching and been happy with the results. One has to wonder in those cases, did they value detail over musicality and natural sound, or was it a great match.

 

It will probably not always be like this, as the the shift to the digital world continues, DAC companies will apply more effort to analog outputs and they will likely get better.
