Not at all. Have used Emotiva XPA-1L monos to drive the DIs for over a year (500 watts) and just upgraded to the XPA-1s (1000 watts). What is more important in terms of performance is Class A power. The XPA-1s have 60 watts of class A and this is enough to make the DIs sing. My XPA-1s deliever more than 500 watts of power to the DIs (can tell by the meter) and they do not mind at all.
Emotiva amps have a strong and deserved rep in the studio world but are not popular on this site. Nonetheless, they are very accurate and match particularly well with the DIs.
Get a pair of DIs ASAP; you will never regret it.
