Burson has built a very solid offering for $699, and I would highly recommend it to anyone looking for a great solid state amplifier up to a $1,500 budget. Its amplifier section is definitely better than the $1,600 Grace m902 I own, and comparable to the CEC HD53N and Lehmann Black Cube Linear amplifier.
