Seeking informed recommendations for power cables and interconnects

In addition, I am also using a Parks Audio Budgie Hybrid phono amp and using AudioQuest Rocket33 speaker cables.

The best advice you’ll get is to try some different cables, either through The Cable Co. or a dealer who has access without an agenda (I know, I can hear the snickers but there are some good dealers out there).
What works for one person in one system isn’t necessarily something you can readily extrapolate and apply to yours- you really have to hear these things in situ.
There are some known ’house sounds’ to different brands, some favorites in terms of synergy with certain speaker/amp combos, etc. but the only way to get to the bottom of it is for you to make informed decisions in your system using your ears.
I have a range of cables, from high end stuff that i use in my main system to a combo of DIY and modest, beer budget stuff in my vintage system.
You’ll get a lot of positive feedback from users who have gone through the process and reached a conclusion based on their systems and sonic preferences. Getting a dozen or more brand/model suggestions without listening wouldn’t be helpful in my estimation. And, cable changes, while they make a difference, aren’t a substitute for a good set up, placement in the room, etc. Do you own a copy of Jim Smith’s book?- that is probably worth getting if you don’t own it.
Have you tried running your amp direct into the wall rather than through the Furman?
PS: there’s a whole school of DIY cable that has gotten traction in the more mainstream audiophile community in the last couple years. That may also be worth exploring. Harder to try before you buy, but some of it isn’t terribly expensive.

Thanks whart, helpful advice. I agree your way is the preferable means to isolate the best performers. I was hoping others who have used similar components may have already been through this exercise.

I ran the amp into the wall before getting the Furman. To my ears, the Furman improved the sound and lowered floor noise.
I have seen Jim's book referenced before and plan to get a copy.

As a fellow Vandy owner, I think AQ is the best choice for speaker wire.
I use the GO-4 double shotgunned to the speaker.
I suggest PM-ing John Rutan (audioconnection). He sells Vandersteen and AQ. and knows just about everything stereo. He can give you lots of free information without trying to sell you something. I think he will provide the best information for your current components.

Yes, I am pleased with my AQ Rocket 33s, so not looking to upgrade speaker wire. I may take advantage of The Cable Co.'s lending library as that seems the most economical way to compare. Just wondering if I should focus on ICs first before the power cords.
