Power Cable Suggestions

Power cords make a big difference. If someone disagree with that. 1)Never ever tried..2) tried with a very cheep system. 3) tried with same quality  cables and don’t notice a difference. Why in forums like that people Stil disagree about that?

Power cord is one of the more incomprehensible things I've experienced in audio. How can a cable that is not a part of the audio signal chain make a difference in sound...but it does.
I've tested a good number of different designs and I do find power cables to make a more noticeable difference in the source components such as CD players than it does in a SS amplifier though.   

Audioquest, particularly the thunder power cord. Also in use are the NRG X-3's for my sources....cd/sacd player, dac...they sound nice to me, and I believe made a difference on the noise floor...it has been lowered a bit, at least to my ears, results may vary...

I second (or third) the recommendation above for Triode Wire Labs. Great cables, and they are relatively inexpensive. As a "bonus", Pete is a great guy to deal with

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
