Consider the Jupiter2000, very musical (and on the warm side but not overly so) yet significant resolution. Can be found here on the 'gon used for about $1k.
I also have an I5 in my system with JA RM7si sig monitors and Zu Cable Julian (bi-wire shotgun) speaker cables. I agree that the I5 can be bright on some recordings but given that the CDP is paired with Zu Cable Warmouth IC's (silver alloy) I feel that this is the main source of 'brightness' in my system (again, only on some recordings).
