Power Cable Suggestions

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

I use transparent audio and have been very happy with the results. They have different levels of cables so you should be able to meet your budget. 

@gosta ~ Don't know if it is weird to invest in power cables without including power conditioning or stabilization, but one needs to start somewhere and the next step for me will be power conditioning.

@paulcreed , @joannism, @scar972 , @audioguy, @thyname, @tomic601 , @hi-fi-high ~ Thank-you all for your input.

I have looked at all recommendations and decided to go with Cullen Cables, who I will contact when I get home and receive the amps so I know what length cables to order.

Again, thanks to all for sharing their expertise, time and thoughts!
