Heard the Dynaudio Confidence 5 recently. Superb speaker!! This speaker was being driven by a 150W/ch pure class-A power amp of very high retail value!
I have noted that the above speaker & the Confidence 3 are 86dB(@ 1m, 1W). It is very likely that the Confidence 2 is also 86dB(@ 1m, 1W). Thus, I agree w/ Echoes - give the speaker some very high quality, high current power amp to allow it to perform its best otherwise, you'd be settling for some very mediocre sound. FWIW.
