I've used Neat Petite 3s and Neat Elites with an assortment of Naim electronics. Neat speakers and Naim are a fabulous match especially for someone who likes rock music. Neat's ribbon tweeter is fast and revealing but certainly not bright. The little Petite doesn't go much below 65 Hz or so depending on placement so you won't get chest - punching kick drum fundamentals, but aside from that there's little to criticize. The bigger Neats go deeper but require more horsepower than the 5i has. All of the Neats I've heard have in common an engaging and lively sound. You'll want to get some first class stands to go under the speakers if you go for one of the smaller models.
My advice would be to find a Neat dealer and listen for yourself - don't let one anonymous opinion on the Internet sway you.
