Look at materials and construction style. +Zanfino. Wireworld describes each series very well to see this. Educational. Usually, OCC $$$ better than OFC $$. Teflon/PTFE and cotton better than PVC for lead insulation. Connectors matter too. Or, if you're handy, save money, or want satisfaction, go DIY. It's not really hard. Can avoid soldering with clamp/screw style connectors or not. Start with speakers. Then do ICs. Source materials via internet like Soniccraft or Parts Connexion.
