I’ve been impressed by reviews of some direct sellers that are worth exploring as they offer high value and generous free trials. On the lower end there’s the Ice Age OFC “Frankencable” and on the pricier side there’s the Snake River Signature both of which seem to punch well above their respective price points. Best of luck.
