I experimented with my DAC going direct to my power amplifier. The sound is good but NOT light-years better than using my preamp. My ’gut reaction’ is it might not be as clear, and the music does not seem as smooth. So, an hour later, after more listening. when going direct, I felt the music was missing something. The music was not as open or engaging when going direct to my power amplifier. The music felt more closed in.
When going direct, the sound was flat, lifeless and without an engaging factor. The additional of the preamp brought things back to normal. I am happy I did this audition so I now know and can forget about it.
For my application, and setup, I believe the preamp is needed to help the music sound natural, clearer, and engaging. My experiment is done. I believe that a preamp makes the music sound better.
I know that other people prefer going direct from a DAC to a power amplifier. Based on my audition, my decision is based on my equipment, my environment and how I listen to music. There is no right or wrong answer since it just depends on the individual. Everyone has a different opinion on going direct to an amp or using a preamp. The answer is it depends on the equipment and the sound you like.
I suggest you test the DAC direct to power amplifier and then make your decision.
I like the above post that says " I will keep the magic with my preamp".
