Isochronism, between the Audio Note Conquest and Audio Note Kit Legend 300B, I chose the kit Legend. It is any day a better amplifier than standard conquest. Faster, cleaner, purer, more authority, very stable under difficult load, still has the AN sound. But recently I heard the Wavac EC-300B and that has given sleepless nights. I am thinking if the MD-300B can do it for me. So it is going to be either the Wavac or Legend 300B for me.
