Paris, I'm no expert, but I'll speak from my experience and from what I've heard from those more knowledgeable than I. I have a McCormack DNA-2 LAE (Limited Anniversary Edition) and my speakers are 86db sensitivity at 4ohm.
1. I believe your MF A300 is a 300 wpc into 8ohm amplifier. If that is true, then your 4ohm load could mean amplifier power potentials up to perhaps 600 wpc. Since that potential exists, the 15 amp circuitry (wiring, outlets, and circuit breakers) could actually act as a govenor and suppress the power required by and to the amp during some to many dynamic music passages. Even at low volume levels the result can be very flat or undynamic sounding.
You could upgrade all electrical to 20 amps. But, again, if you have other components using that same 20 amp circuit as the amplifier, you will still encounter the same affects I mentioned above.
For example: I had my amplifier on a 20 amp dedicated circuit but I also had my preamp on that circuit. No big deal as the preamp only draws something like 33 watts. When I finally installed another dedicated line for the preamp, the dynamic headroom just blossomed!!! And most of my listening volume levels are at about 1/10th full volume. That's low.
2. When it comes to cleaning up the electrical, there is no such thing as overkill (within reason) so long as you aren't try to improve the sound of your am/fm clock radio.
Suggestions:
a. You should entertain 20 amp ratings for all electrical related to the circuit for your amplifier. This would include 10 gauge Oxygen Free Copper (OFC) romex wiring, a hospital grade 20 amp wall outlet, and a 20 amp circuit breaker.
b. For your pre-amp and turntable, you should consider a second dedicated circuit at 15 amps for the electrical parts. Keep using the 10 gauge OFC romex here also.
c. For your cd player, you should consider it's own dedicated circuit since digital processing has a way of introducing digital noise back into the wall. 15 amps is good here as well. Keep using the 10 gauge OFC romex here also.
If you do these inexpensive things, you should notice some very serious improvements at the micro-dynamics level as well as a few at the macro level.
Hope this helps a bit.
