Why not buy the NAD pair which you like?
HiFi electronics are not supposed to have "character." They are supposed to pass an electric signal from one end to the other unscathed except for amplification. Any character they possess is distortion. Leave the character up to the musicians.
The vast majority of the "character"/distortion a system has is coming from the speaker/room. Now it is a matter of choosing your poison or perhaps stumbling over it.
