Power conditioner vs use of a audio grade outlet?

Look into Furutech GTX-D. These are top of the Furutech line and feature pure copper base with either gold or rhodium (regular or NCF).

Power is key. Don’t plug your system into a garbage outlet.

The small upgrades are additive. With the tiny cost involved a high end outlet is a no brained. 

I have a Saturn 103C conditioner, that was an amazing upgrade in itself. I have all Wire Work silver electra 7 power cables. The icing on the cake was a dedicated 20 amp circuit with a Cardas Audio 4181US wall outlet. Best money I ever spent. You will hear the difference.

Yes, you definitely want a good wall outlet. There are various options available. Hopefully, a dedicated circuit going to that outlet.
