My regular speakers are Merlin VSM's with VAC amplification. My current project is to rebuild a vintage McIntosh MC240. I didn't want to ruin my Merlins if the MC240 did anything weird, so I bought the best pair of speakers I could for $200, the TC50's. This past weekend I get half the power supply rebuilt and hooked up the 240 to the Spicas and was floored by the sound. Certainly not as detailed or as open as the Merlins, but the Spicas do have that magic. All that being said, I'd add in a sub if I was you and continue enjoying the Spicas. One of the best bargins on the used market.
I haven't heard the GM Europas, but their reputation says that it would probably be a great speaker for you as well.
