Hello,

I use presently two 405-II mono-blocked in parallel way with ESL63, and I appreciate the sound.

Is it recommended if upgraded them with high end dada cards and staying mono-blocked ?
I mean is there any interest or is it useless ?
Is there more risk to damage the amplifier output with high end cards if mono-blocked ?

Thanks for information, Ronan

I'm not much of a believer in monoblocking in general, but in any case you certainly don't need monoblocking to drive an ESL-63, as it already has lower limits on its input than a single 405 channel can provide. I would undo it and repldoy or sell the second 405. But make sure you have the voltage limiters in place inside the 405 that you keep.
