Higher end value cables

Lots of good suggestions.  Call Steve at The Cable Co. and see what he recommends, as well.  They do have a lending library that will let you audition candidates at home.

Wow, good advice. I have a tube jolida preamp, and a wells audio class a power amp that has an excellent tube sound. Anybody recommend interconnects that would compliment that approach?

That is, in the price range I talked about

Ah.  Sorry I misread your post.  So, just for reference and now that we know what you're looking for, what interconnects and speaker cables are you currently using?   It just helps to know what your current reference is to help make better recommendations. 

That said, in my experience you're looking for a tough combination of traits at that price point.  Off the top of my head and if I'm you, I'd demo some Morrow Audio MA2 interconnects and maybe also SP2 speaker cables.  You might be able to strike a deal with multiple cables as well and very low risk to demo on your system, which is invaluable.  I'd be surprised if you're disappointed, but if you try them make sure they're broken in before making any firm judgements.  Again, best of luck!

Thank you. Actually this is a brand new system for me and I need interconnects. I do however have tributaries speaker cables. I will look into these suggestions. It seems to me that for a tubey sound copper might be best, as I understand silver can brighten things up a bit
