There are no $25 best interconnect cables. As a rule of thumb, if your components are under $1000, Decent cables such as from Monoprice work fine, and you don't need more expensive cables, or even a $3000 cable doesn't make any difference. If you components are between $1000 and $10,000, Blue Jean cables work fine. BJC uses Belden and Canare cables, Neutrik and Switchcraft connectors, and a few others. If your components are more than $10,000, then look for better cables. The total cost of your cable is no more than 5% of your system. I make my own cables for a $50K McIntosh-Focal system.
