Power Cable Suggestions

OP yes take those first steps to go somewhere!!!!! I would advise since you have some Audioquest in your system calling John Rutan at Audio Connection in NJ - he should be able to help you hit your target budget and have a good discussion about what you are seeking to improve:-) also at bare minimum put some $$$ in the plan for Hospital grade Hubble and cryogenic if possible. For budget it is hard to beat the PS Audio Powerports :-)
have fun, enjoy the music and the journey 
best to you

IF you don’t know where you are going, any cable will get you there....
