Onhwy61, I agree that phones are capable of excellent bass that you can hear, but to get the full effect you need bass that you can feel. How about headphones and a sub? Still no soundstage though.
Pawlowski, As for speakers I think you are on the right path exploring high efficiency speakers but not because of a small room, rather I think that they sound the best, and you will need them for the amp you have.
Monitors that will work well with an SET amp are a rare breed. To get any bass out of a small cabinet they must be inefficient. To get bass out of an efficient driver takes a big cabinet. In a small room with your amp you need a high efficiency speaker in a moderate size cabinet like the Lowther medallion and a small sub. http://www.lowther-america.com/
