ARc CD3 Repair follow up Question

Since my CD 3 returned from ARC having to have 5 power supply caps replaced, I have protected it now with a Shunyata Venom Defender. Where my question lays is that (yes, it is great to have it back in place and listen to music again:), Will or should the new caps have an effect on the sound? I have heard better (and some before hidden) insturments and recorded information) and this could be the help from the Venom Defender also but, I also do hear some amount of change in what I hear in the presentation too and I am attributing that to the differences in recordings but could this be from the new caps as well? and do the caps continue to break in even when the CD3 is only in stand by?
