Seventh Circle Audio

Hi everyone.
I test my pair of C84 with the maximum level output. I recorded it in logic via rme ff800 with 44,1kHz 24 bit. No source.
My rme shows me -100dB in input when the level is set to 0 with the preamp.
I obtained -54dB when set at max level.
I know we have a great pre with 70dB gain ! So is it a cool result or can I improve it ?
Thank's Marc
PS: I never hear my se1a sound so natural and neutral with !!!!
