I'm running the Europas with a 30 watt/channel hybrid amp with excellent results. The amp has more than enough power for the Europas. Honestly after listening to many monitors I can detect no weaknesses with the Europas. Their low level detail, transparency and soundstaging are unsurpassed in my opinion. They can play very loudly and at the same time retain all their musicality at very low levels which many speakers cannot do. I've tried several cables recently and in each instance could very easily hear differences between the cables. They are not a warm sounding speaker however they are very fast and live sounding and do an incredible job of bringing the musical event to the listener. They play all types of music well even though they do not have deep bass. The bass they do have is very tight and detailed and I have them supplemented by a rel sub. If I had to point out any weakness it would be the long break in time. These speakers need at least 200 hours to sound their best. They improve tremendously from about 100 hours to 200 hours. Also, Roy the owner is a pleasure to deal with.
