Thinking about going electrostatic

Got that itch for speakers again I have a pair of Joseph audio pulsar and a pair of talon khorus.  I like both but now thinking about martin logan my budget is 3 to maybe 4500 I would look for a used pair can't afford new not to concern about bass I have a talon roc sub. Speakers would be powered with a rotel 1090 and prima luna dialogue pre amp. Have never herd of that type of speaker. Would like to here your thoughts
