Will ARC VT-100 drive Dynaudio C-1's

You have received sage advice so far.
Most Dynaudio speakers are current-hungry and their usable dynamic range is from mid-volume to very loud. There is not much definition at quiet to moderate levels. These are speakers designed to sound best when played LOUD.

OTOH, most tube amps excel at low power. There is an increase in harmonic distortion as one demands more power.
All in all, IMHO, this is not a synergistic combination. The amp is fine when the speaker is coasting (but sounding bland) and the speaker sounds its best when the amp is fully stressed (therefore adding THD).
If you must try the combo, use the 4 ohm impedance tap and short/thick speaker cables.
Good luck

Keith, my post was in light of Tater's specific question: Dynaudio + ARC VT100.

You may be correct regarding VTL 450s, I have no experience with those amps. Maybe they can push enough current into the Dynaudio's average 3 ohm impedance in the bass to make them come alive.

I did not mean to imply that tube amps are built this way or that way. I have been an user of tube amps for the past 25 years, I love tubes.

I would say a minimum of 200 clean, solid state Watts is the basic requirement for driving properly those speakers, unless Tater listens at background music levels.
