What's "wrong" with your sound that you'd like to improve? I'd suspect that it's unlikely that one set of cables would be the best for all of your speaker options.
You might try www.thecableco.com and use their exchange program to try different things. There is also a used site associated with them.
What do you have now for cables?
Blue Jeans cables would be a budget recommendation.
If your total budget is between $500 and $1,000. that is the place i would start.
You want a consensus on better cheap cables, and Blue Jean cables gets the most recommendations for new cables.
Other wires are Kimber PBJ interconnects, 4TC speaker wires., buy the 4TC used.
Npdoherty...I wouldn't select cables ahead of deciding which speaker you are going to keep. You can then use cabling to match the rest of the system with the speaker selected. Using the Cable Co. is a good way of taking advantage of their lending library to try out different brands/models. If you have a local dealer, I would also see, if they have a bunch of different cable looms that you can use. Some brands to consider:
Entry-level Transparent won TAS Budget Product of the Year award a bunch of times
Kimber Hero interconnects and 4TC speaker cables also won TAS Editor and Product of the Year awards (you will probably have to buy used to get in your price range)
If you can borrow either of these and test them out, that will be a good start.
Morrow audio cables. I have ICs and PCs on my McIntosh amps and preamps (tube and SS), and they are very, very good together.
Analysis Plus has several models to choose from or you can review DH Labs.
Analysis Plus used on MC275 and C500 components.
The Cable Company seconded; you can go through a lot of cables, listen, and finally decide which you'd like to buy - in a situation like yours, it's the only way to go unless you enjoy spending a lot of money for naught.
Every system is different, as are every listener's expectations; synergy is everything in the world of cables. Blind recommendations are just that: blind. Only you can decide what will work and what won't.
I agree w/Mceljo. If your system sounds good as is, leave well enough alone and save your coin. But if you need something new, I say look at one brand's lower-end models to keep cost down. Mixing and matching is just opening the door to a whole lot of wasted time and second guessing, IMO.
I'll throw in my 2 cents as well, I'd try contacting Grover Huffman and ask him some questions. I am fully wired with his Sx IC and Se speaker cables and yes it did make a difference with my Apogee Slant 6s :) and he is very cost effective as well. But also I have to agree with everyone else as well and say that you should decide what speakers you're going to use but.... Grover's cables are (IMHO) are a world beater.
I went with Home Grown Audio DNA / X-32 and have never felt the need to change. I switched from Audioquest Volcano and Anaconda. The HGA cables are better than the Audioquest cabling they replaced. Much more revealing and natural.
HGA offers a 30 day free trial..
You kept the same wires for years!!!! Shame on you!! I hope you don't consider yourself an audiophile. Suppose everyone kept their wire for years??? How would the snake oil people keep their S classes and afford their life styles Think of other people sometimes!! It's not just about yourself!
Rok2id, I fully agree! The snake epidemic would be horrendous with many not being culled out for their oils:)
Not to mention the imposed Charlatan tax break that we would all absorb!!
Palasr - Ironically, a blind recommendation plus placeo is probably worth more than we'd like to admit. If I think it should be better, it likely will be better. I have a few tweeks that fit this criteria. The issue is finding a method to make a placebo proof comparison.
My grandpa once told me that he didn't care if something was a placebo as long as it worked. It's difficult to argue with that logic.
Mceljo- I agree. In fact blind recommendations (usually via forums, magazine reviews, etc) plus the placebo of 'it costs more so it must be better' have kept many a cable manufacturer in business for a long time. Being purely objective in one's assessment of anything audio is difficult at best.
Thanks for the great responses and suggestions. I'll certainly look into something like Cable Co. I'll get back to you when I do decide or comment on what I tried (pro's/con's).
Thanks also for the light banter on not keeping the rich richer as I have not bought any 'snake oil' cables in some time. :p
