Sound Progression

A week after I've got the pair of speakers (ML Aeries i) and amplifier (Dk Design) I've finally got my Oracle Delphi turntable with Denon DA-401 tonearm and Denon DL-301 cartridge.
Before today I've been using danish (or Swedish) Primare CD player ($1100 version). Holly Molly! What a difference!
It is hard to believe that the difference between vinyl and CD could be so dramatic! I have now it all - from low bass to crystal clear highs! I am amazed.
As you probably know DK Design has integrated phone-in.
One thing I noticed is that if with CD player I rarely turned volume dial to 11 am position - with turntable plugged to phone-in I can turn volume to 3 pm position...even to its limits - to 5 pm. I wonder if it is common. I guess electric signal from turntable is several times lower than from CD player. Is this normal?
