Box speakers that sound like Electrostats?

I just did a demo of piega p10 with lamm amp.The more powerful one.I cant remember model it was at a dealer.I really wanted to like this speaker but was not impressed except on a chorale CD.This speaker has air.Better than on any speaker i have listened to.It would be wonderful on full scale classical.I listen mostly to Jazz and my Newform Research 645 are more open and way faster.Imaging way better and depth much better.It alo has a punchier mid bass.Bigger more realistic sound stage.Resoulution in spades.I was glad i demoed p10 i was going to buy them because they were more expensive and thought they would be much better.I am not trying to sell you on these speakers because my kharma 2.0s are my favorite but a more slower relaxed sound.I biamp aloia 13.01 amps or bedini 200 classic
