This is great. There are some really thoughtful options offered here that are really promising. Thanks everyone for taking the time to contribute.
Knowing that are multiple viable ways to go I want to share with you what I'm thinking and the best way to do this is too stick with the ferrari / jaguar analogy as this is my compass.
Which takes me first to the bigger box option (Kef r3 or Dynaudio 20,30, or 40). They are in my price range and I can see how a little rolling off the top freq and solid\wider lows would give me a different experience. The soundstage I think might even be somewhat wider. Staying in the Kef line plays it safe as I get a modified ferri (toned down). Motorcyle manufacturers do this all the time. However going to the Dynaudio definitely guarantees a different experience. I move from a ferrari to a jaguar...big move. Would I miss some of the Kef's accuracy and precision? I don't know. Right now I'm leaning towards a Dynaudio.
What I also found is a viable option is a sub! Thanks for all who mentioned this option. Your points are well taken. However I would still be in the Kef line and have a modified ferrari. Again would this be too safe of a move? Rather can I get some of the same characteristics of the Kef ls50s with a Dynaudio or other and also include a sub. With either decision Kef R3 or Dynaudio I'm still going to give a sub a try. Thanks Turnbrown and others for this suggestion.
As far as amps I think I have those covered if I go with the Dynaudio...I have the NAD 326bee (class AB) and a Mcintosh MA6200.
As far a responding to a couple of other thoughts. Concerning - the Harbeth, I just fear it will be too soft\laid back from what I've read. I'm not a grandfather yet and not ready for the sporty Cadillac. But again who knows?
Concerning the Aegir and Kef Ls50 - I think a lot folks discount Class A because of the heat and low watts. Yes there is some heat but the constant flow of current to these speakers does something special. I tried it and just like others who have experienced the pairing of the Aegir and Kef LS50s it is very, very good. Especially if you have a good preamp.
So, I again I truly appreciative of all the input. I also think my car analogy is helping guide me to this decision. I'm going to try a Dynaudio 20, 30 or 40 and with a sub a little later down the road.
