Reply to Simple gain question

Im using PN for normalizing my collection, have been doing so for over 2 years now. I only use it to repair clipped peaks and set gain.

Proplem: somewhere along the line whilst upgrading versions my gain setting got changed to - 13.9, now I might not have ever noticed this except that i was just using traktor and the waveforms seemed a little thin.

Question: If ive gained my tracks a little low, therefore when playing out i have to increase gain to + 3 or + 4 for example, is there a loss in sound quality?
