@ronkent If you really want to beat your Coda 16 then settle only for the best solid state amp from BAT, the REX-500. I am not so sure that the REX-300 will do you any better than what you already have (the CODA 16 is fabulous). I am considering selling my fairly efficient speakers (next year) and opting for a speaker that is more power demanding. At the top my short list is the Sonus Faber, Amati G5. At that time, I would sell my BAT VK-90T power amp and get the REX-500 power amp. Time will tell, but first up is completing the new sound room addition. I just received the construction quote yesterday and it is within my financial plan. Ultimately, my end-game system, in total. Life is too short, enjoy it while we are able.
