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

The C-1 is a wonderful speaker, ruthlessly revealing of anything in the food chain, exposing the weakest link.

While the ARC is a fine sounding amp and in moderate size room will be more than adequate, to really make the C-1's sing you will need 250 watts or more per ch.

While I have heard suggestions that ss amps work best on this speaker because of the low sensitivity, a big tube amp lifts them to a special plateau.

It all depends on how big your room is. In a smaller room yeah they should work great together.

i think the C1s will work fine with VT100 in a mid sized room, though i'm not a huge fan of that particular tube amp.

i would like to try VTL 450s on the C1 as well as Krell 400cx.

i had the Pass X250.5 and it was a very good match for these speakers. i use BAT integrated now as i'm not as big into 2 channel.

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

Agree with Casouza. For the C1, use a high current, high quality SS amplifier.
