There's a Creek OBH-8 for sale and I'd give that a try. I own the OBH-8SE which has the larger power supply and it is very enjoyable to listen to. (Presently using older Project TT w/stock Oyster Cart.) I had the Sumiko Phono Box (Original version) prior and the Creek was a HUGE step up. Your NAD and my former Project pre-amp were probably in the same class. Good Luck!
