Soundsource: does this app degrade the source?

Does it make sense to employ this app for inexpensive EQ--or anything else-- in an audiophile system? Has anyone out there tried it? There's a free 20 minute trial, but I don't trust my ears as much as I trust y'all's.

When it comes to judging sound quality only trust YOUR ears with YOUR equipment, in YOUR room. That’s all that matters.
