Other Notes: This power amplifier features 200 Watts per channel at 8 ohms, enough to drive a wide variety of high end speakers, and would be a great addition to any audiophile system. The updated, upgraded components provide even greater dynamics, imaging, extension, transparency, and a quieter background than when it was brand new. Nelson Pass's time-tested design with a 2010 rebuild and under 50 hours of use since the upgrades makes this a true gem.
