Blue Jeans Cable Sound Good???

The copper does make a difference!! I owned a pair of the TPC speaker cables for 3 years and they were amazing. I have upgraded my system this year which included the SPTPC speaker cables. These are not “super expensive” cables when you look at the market. A 10 ft length of the TPC speaker cables is $1600. There is a no hassle return policy if they don’t meet your needs. I would suggest that listening will show you their “real value” more than reading. 

I bought a digital cable. Step up from basic that's all. Look for better stuff used

BJC LC-1 interconnects are really good for runs longer than 4 meters.Its very system dependant using this series of cable.If you have a overly bright system it would make it worst but if you need the hardness smooth these are fanastic cables for the price.I owned the Cardas Sky,neutrals and microtwins and I say these are on the same level as the neutrals.I tried long runs of other entry level brands of less than $150 a meter and these are my favorite hands down.It may not work for everyone but for me I needed a pair of long cables that has decent shielding,doesnt colour the music and doesnt break the bank.

I can vouch for their Sub Woofer Cables.
Absolutely first rate!

I find BJC to be a great value for the money. They will custom make them to the length that you want and attach a decent connector. I have never had an issue with them. Are there better cables out there? Of course, but I don't see many at that price point.
