Help Me Get Out Of The Dark Ages

For 19 years I have been happily living with Dynaco A-50 speakers. Remember them - two-way with a 1.5" tweeter and two 10" aperodic drivers. Over the years there have been various electronics behind them. The end of 2001 I splurged with a Creek 5350SE integrated amp and a Rega Planet 2000 Cd player, as well as assorted combinations of Cardas cables. The result is that the A-50s sound better than they ever have. So what's the problem? I know there are a lot of good speakers out there that are more detailed with better imaging, sound stage, etc., but I really like the Dynaco sound -smooth, neutral and bassy. Can anyone that remembers the Dynaco sound recommend a speaker that is somewhat similar and that would work with the the Creek and the Rega. My price range is up to $3000 new. Any help would be appreciated
