Regardless of what a dealer will tell you. The Hpa is a great sounding amp.BUT the Levinson 300 series will blow the hpa into another time zone and thats a fact. I used to own a Levinson 331 with a Pair of B&W 802 series 3 matrix and it sounded very good. I have heard the new 300 series on a pair of 803n and was blown away. never harsh or grainy just very musical. Good luck
