Some additional comments. Below is link explaining what I did to Emotiva Gen 3 DR2 amps, which helped but still did not provide super deep strong bass (example of switching power supply):

Moving on, the only time you really want a low gain setting on an amplifier is if you have super extremely efficient speakers (I’m talking 99-100db efficiency, such as something like Tekton Double Impacts). What happens is that these speakers are so damn efficient that the background hiss that is present in all gain circuits is radically amplified and you have this annoying background hiss on whatever you listen to. The fix for this is a low gain setting on your amp.
Since your Phil 3 speakers are actually a rather low 85db efficiency, you want a normal gain amp (even one that tilts towards a higher gain such as 32db gain).
