" …….. I ended up splurging on a pair of LFD PA3 mono blocks ($7500 retail) because they were just better. Not by miles but definitely an improvement into that high end audiophile land that the RWA could hint at and come close to but just not as quite as finessed as these. I still use the Isabella with them. If you can afford to buy them the LFD mono's are just gorgeous sound. As perfect as I've ever heard."
