Higher end value cables

I’ve been very satisfied with cables by Audio Sensibility in Canada.  They use mostly all OCC cooper and silver to make their cables.  I’ve had good results with Audio Art cables as well. 

For my amplifier - LAvardin IT - both types of DNM cables work very well - in fact I use and have some Nordost Heimdall 2's and I found that the DNM's gave a better sound with better flow and cogency.
I spoke to LAvardin on the premise I required cables longer than they manufactured and they recommended the cheapest Nordost cables - called 2 FLAT - they told me to save my money and not waste them on more expensive cables.
I came across some cables by a company called 'wire on wire' and in the set-up I heard them in they were good and very affordable.
There is another cable that I have used by a company called 'Missing Link' in the UK as well

Thank you all for the advice. Have some research to do

If you know which aspects of sound reproduction are most important to you and/or know areas in your system you'd like to improve, read some reviews to see which cables seem to excel in those areas.  When you find one or two that seem interesting, just buy some used cables and give them a shot.  If not a big improvement over your BJC you can likely sell them at little or no loss and move on.  Some usual suspects would be Acoustic Zen, Audioquest, Synergistic, etc. 

Another route would be to try those manufacturers who sell direct and offer in-home trial periods.  Morrow, Triode Wire Labs, Grover Huffman, etc.

Hope this helps and best of luck. 

Definitely helps soix. I don't actually have any bjc cables. I know I like a tubey sound.  I love clarity, separation and details, but I also love that dead silent...inky sound. I love the sound of analog as well!
