Long ago, I owned the Final 0.4’s. My Carver Research Lightstar Reference amp drove them beautifully. Powered subs filled in the LF. The customer service was phenomenal. During a move, a panel was damaged. The U.S. distributor quickly sent me a matched pair of replacements. Kudos to Final Audio for their continuing R&D.
Final-Audio New Series electrostatics
I am a fan of Final-Audio Electrostatic speakers. I have transitioned to the current models. Any others out there in audio land using the newest iterations? The M series.
