Software recommendations

I am new to computer audio. I am not into the "Tech" and really just want easy, trouble free sound. I have been using Amarra 3.0 for down loaded music, and Amarra sQ for spotify, and though I like the sound when it is working, I have found it to be unreliable and unpredictable. Reading reviews has not been helpful as most reviews are more ad copy than critical evaluation. I would appreciate your input as to good/bad of various options. My primary concern is #1, ease of use and reliablity. #2, sound quality. #3, cost.
thanks.
