Tim Smith has posted a review of the Naim Supernait 2 integrated amplifier ($550) at Wall of Sound. His conclusions:
“First, you are getting 80 crisp and clean watts with ample current and drive. You are getting world-class pace, rhythm and timing. You are getting an ultra-quiet world-class preamp. And a world-class headphone amp. All in one box. And it will last 25 to 40 years. Yes, the Supernait 2 comes with a headphone output. I plugged in the Grado GS1000i, the HiFiMan HE-400, and the Beyerdynamic DT 800 and 770. You are getting a $1000 to $1500 headphone amp not unlike a Burson thrown in to this mix. Highly recommended, especially for those looking for a one-box solution to their amplification. For most people this is all the amplifier they will ever need.”
