So you're telling us that your LP's sound better when you convert them to digital, and then back to analog via your computer, and then put the signal through your amplifier to your speakers, versus when you send the analog LP signal through your (phono) preamp, and then through your amplifier to your speakers. Do I have that right?
Interesting results.
However, it would help us determine what to make of this finding of yours if you could provide us with a list of your system components, particularly:
Your turntable;
Tone arm;
Cartridge;
Preamp, (including phono preamp, if any);
Amplifier;
Speakers;
Without knowing all of the key components of your experiment, we can't examine the reasons for why your results are what they are.
