Best Line Stage Preamp?

Hard to answer "best" type questions, since most people's sampling of available products is small or shortlived. I can say that I love my CAT Ultimate and prefer it to some preamps I have owned in the past, including: Audible Illusions 3A, McCormack Passive (TL1?), and several ARC preamps I have used in the past. You need to make auditions with CAT on your must listen list.

I am surprised that we don't see brands listed here such as

Audible Illusions
Conrad Johnson
or VTL.

Any praise for these?

I've had both the passive and active Placettes (I think I may have actually bought one from Stehno) and there has never been a problem with dynamics. I was amazed how just the bass extension and dynamics improved with even the passive. If you are careful with cables and vibration sources using them, you will be amply rewarded.
