Help ! Levinson No333 or No.33H


I have been gave a good offer in upgrading my No.333 to No.33H. Is it worth to go for it? Anybody made a direct comparison between this 2 amps? I am worry that the 33H(150W) will be lack of punching if compare to the No.333(300W). Appreciate for any feedback.

Ugin, the 333 is stereo and 33h is mono. Are you getting another unit to complete the upgrade?
