Let me throw an alternative into the discussion. I was shocked but I found really good anti vibration feet an anything can make a huge difference. They worked under every piece of electronics I put them especially under my CD drive(it was a brand new machine). They add clarity, detail, transparency and detail. Plus I haven't done it yet but I've heard the same thing under speakers. Good ones aren't cheap but they're far less costly than new speakers.
Looking for Speaker Input
My system is Luxman C900u pre amp, 2 Luxman M900u amps configured in monoblock mode driving Focal Sopra 3 speakers. All digital with Aurender W20SE streamer. DAC is Luxman D10x, which doubles as a CD/SACD transport. My question for the forum is I think the Focals are the weak link. What speakers would the forum recommend to go with the rest of my gear?
