Chord Ultima Pre 3

I was wondering if anyone has been using a Chord Ultima Pre 3 preamp.  I have one that I'm demoing and I like it, but was curious if anyone had run into any issues with a lack of gain on this preamp.  I would not be using it with a Chord amp and the only way I can get it loud is by using the balanced inputs--and even then, at full volume, I'm barely hitting 90db.  I don't do a ton of listening near that level, but it does seem to be a fairly low limit for something turned all the way up.

Amps are 100 wpc and speakers are 100db efficient so this seems odd to me.  Does anyone have any thoughts?
