A few years back I swapped out my Adcom 565 pre for a Creek OBH-14 DAC/Passive pre. It absolutely tranformed my system and really got me back into "listening" and, consequently, audiophilia where I started upgrading everything else (and later the Creek preamp too). In other words, the 565 was the weak link in my system at the time, bettered by a much less expensive passive pre. I think a Creek 5350 SE would absolutely transform your system for the better, to the extent of a "whow" factor. Go for it.
