I’m going through a similar process. I own the Revel 228be, and I’m very happy with them. They do so many things well----imaging, detail, midrange grip, good bass (provided that your electronics are up to snuff), versatility with different genres of music, and they're not finicky about placement. I’ve also had an itch for the 328be, since I’m in a large listening room that can utilize it, but something tells me to leave well enough alone.
Speaker changes are a dilemma. The mistakes can be expensive and auditioning is difficult---bad combination.
