In all seriousness, monoblocks do not guarantee a bigger soundstage and images, better dynamics and better overall sound.
Any recommendation to that effect would be the voice of inexperience speaking.
A well engineered and implemented stereo amp will smoke its' poorly designed counterpart. Given the choice of 300B products would you choose a pair of Ming Da monoblocks over a VAC Renaissance stereo amp? I think not.
I have no financial interest in either line.
