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.
I am also interested in the answer to this question. Unfortunately, no one is willing to answer it online.
I did have them both and I did up grade to......guess what???? If you have any questions e-mail... Tommy ;-)
This is not a hard one. I don't think the 333 even sounded that good, and the 33h is pretty righteous. If nothing else I think the soundstaging on the 33h is significantly better. If you have the cach that is a very good upgrade.
Cash, sorry, bad typo. Also the power issue should not be too significant unless your speakers are very difficult to drive.
