If you enjoy more of a laid back sound, perhaps look into the Odyssey Epiphany ($595 plus shipping) and, provided the NAD has a sub out, couple that with a Rocket UFW-10 sub. If not, the Adire Audio Rava should suffice. Could look at the Shamrock Audio Keelin or the VMPS QSO 626SE. Do not rule out the used market either for you may come accross a deal that is too good to pass up.
