Parasound P6 Volume control increments.

Greetings everyone. I am currently auditioning a Parasound P6 preamp and I really like it. Very musical and also I find it neutral. Super quiet. I noticed that to you don't get any substantial volume until you get to about 50 in the volume display and up from there. I think it goes from 0-100. At around 65 it really gets going but I don't understand why Parasound chooses this level of step control. I am running it with a Krell KAV 250A Power Amp and Marantz Sa11 S1 completely balanced. Table is a Rega Planar 6/ Exact. Obviously you get a gain of 6 DB when using a balanced connection. I have also emailed Parasound and I am waiting to hear a response. I appreciate any kind of input. Thanks to all and stay safe and healthy.
