I have used the Karat M-70(pre-curser to the Ref DC series)for 10+ years in my main A/V system.Thus far,nothing has been able to displace them.I have also hauled them down to my 2 channel room where they aquit themselves quite well.They may be the best all-around speakers that I have heard.My wife loves the way they look(slim,tall floorstanders with side-firing woofers in cherry wood veneer finish).I face the woofers inward.
