Anyone compare Dunlavy vs Aerial

Without delving into the sonic differences, nor the match between your amp (of which I know absolutely nothing) and the speakers you list, I would submit that the Aerials and Dunlavys are not the easiest of speakers to drive, maybe a bit much for your amp's 40 watts. I own Aerials and as many here at this site will tell you, they are a little power hungry. The Proacs may match better with your amp, from a power/current standpoint. Even if the deal is that good on the Dunlavy's, if you couldn't fit the Proac 3.8s, how ya gonna fit in the SC-IVs? Those things require an addition to most houses to enclose them. Maybe an amp would fit into your future? It certainly would open up some possibilities on other speakers.

My opinion, for what it's worth.

I own Dunlavy SC-Vs and auditioned the IV's. They are great speakers but they need a big room and a big amp. My room is about 8000 cubic feet and I drive them with 400 watt custom modified Melos Soloist monoblocks.

I can't agree with the above posts. I own Dunlavys' and they are far superior to the other speakers you mention. They do not require 400 watt amps. In fact, a friend uses 15 Watt (Yes, 15 Watt) tube amps on Dunlavy SC-V's with great results. I use 25 watt (at 16 ohm) tube amps on Dunlavy SC-III's with excellent results. You may need more power using solid state amps, but this should give you an idea of how efficient the Dunlavys' are. They sound their best bi-amped. If you don't want your friends SC-IV's, let me know.
