Anyway, I've got a high-end set-up but I am having fun during/since lockdown building a DIY, low-cost system and seeing how darn good low-cost speaker drivers and digital amps and streaming boards bought online can be. It's amazing what you can build with very little cost if you put in the time and have the interest. All the building blocks to make active, app-controlled, whole house multiroom are available for next to nothing online now. Fun times for music lovers and those that like to build cool stuff on a budget too!
