I have a Dynavector 10X5 on a REGA P3 with the Manley Chinook Phono Pre, 45db is more than adequate for the 10X5! (this is my goto backup rig) I also have a Pro-Ject Xtension 10 with a Dynavector 20X2 Low .3mv and 60db is plenty for that cartridge as well. I use the Manley for both and switch cables around (when needed). I love both these setups, very satisfied.
