Hi @emarcano,
To my ears they sound phenomenal. Wide,deep soundstage. Great texture,and tone. The J2 seems to drive them with ease. I use the J2 in my main system in the winter months,and my secondary system in my finished basement in the summer. The J2 does run hot. I definitely would not put it in a cabinet,it needs to have airflow. I would highly recommend the J2 with the Nolas. Keep us posted.
