I found preamp to have a bigger impact on sound than I expected and matching with your amps is critical. I have tried eliminating it via the preamp stage in a DAC and found it was a huge step down.
The preamp May add colorations, be less pure, add distortion, etc, etc... I don’t particularly care. My desire is to have an engaging and enjoyable system that delivers an extraordinary listening experience. The “purer” the sound tends to be the less engaging on many recordings.
