Is Pre-Amp needed

Right now my preamp sent for upgrading and I use direct DAC /power amp! It works but a bit dry and raw to my ears, a good preamp adds more taste to the sound and I already miss mine. If you want to have analog setup, preamp is a must for volume control.

Based on my limited experience, preamp is most important part after your speakers. You can read all the numbers and statements that logically sounds correct but if you add a good preamplifier, you understand why people use preamps.
p.s)Some DACs equipped with a in built preamp but still I prefer a separate preamp specifically a tube preamp!
