What are the alternatives for Kimber and Cardas?

My first choice interconnects for my gear is Kimber Kable Select 1021 rca, then the second is Cardas Gold Reference rca. What would be a third comparable rca interconnect that I should look for if my budget is strained? Gear: Plinius M8 Pre amp, Plinius SA 102 amp, Oppo 83 SE Nu Force edition.
Here's another vote for WyWires. They were rated #1 in their price category in a recent PFO review. There were some well-known names on the list. So I installed WyWire IC's earlier this week. Thus far what jumps out most is the realism and emotion in the music.
Some cables accomplish this by putting slight veil over the music ... rolling off the highs. Kind of like using a filtering lens on a camera; but with these cable the notes are rounded, yet still maintain detail and "musicality". I feel a bit closer to a live performance. One place where vinyl excels over the best digital is in reproducing the piano (IMHO). High notes from the digital side usually sound a bit "tinkly". These IC's really help tame that while still letting the full weight the notes flow through.

These cables display incredible micro-dynamics and musicality. There is a very good CD for testing dynamics. It's "Gershwin's World" by Herbie Hancock. It has a number of cuts where there are crescendos, then the music fades and gets very quiet. WyWires handled these changes effortlessly. Voices are very natural too. I was listening to Diana Krall "Love Scenes" last night and she sounded so natural and engaging. I've seen her live by the way
... my wife called me a Diana Krall groupie! At any rate, besides the near perfect timbre, what I like most about WyWires is the tonal balance - from top to bottom.

Everything else I've heard seems to be lacking in some area or they over-emphasize something else ... like the high's, low's, or mid-range. With these cables, everything is focused and coherent. Bass is tight and controlled, but still has some punch. Mid-range is present and blends well with everything else. Beyond that, they are very quiet, clear, and clean ... not a hint of grain anywhere. Finally, WyWires have great sound staging with excellent front to back layering. I could sit and listen all day/night.

The company has a 60-day trial period, and cables are custom made. That said, the only real way to know if they'll perform in your system is to try them. Good luck, and happy listening!

Steve is famous for his digital gear but his interconnects and speaker cable have an incredibly beautiful sound. They are definitely in the warm school of cables but not has strongly as cables like Cardas.

Also the original Audience speaker cables AU-24 (not the AU-24E and not the interconnects) are, in my experience, also amazing and in the same family of sound. Also they look really cool - thin black wire.

BTW, I like the Audience AU-24E line very much as well, but it is much more fast, detailed and neutral than the original AU-24 speaker cable. They strike me as very different family sounds - which is unusual for a single manufacturer. And both are wonderful, IMHO, in appropriate application.
I would try xlo . Reference series and up , I think they are great cables but ultimately it's up to you and what you like.
