it is a matter of degrees. the 33H's have plenty of punch and slam......especially if you wire them for 220 volt operation.........but........when i switched from the 33H's to the 33's......there was much more control and lack of congestion on the musical peaks (with my Wilson WP6's).
so my conclusion was that with speakers that can take advantage of mega-current (such as the WP6, Theil 7.2's, and Revel Salons) more is better.
keep in mind that getting the refinement of the 33H's with more slam won't be cheap.......you may find there are trade-offs. then it becomes a matter of priorities. even though the 33H's are getting to be a little long in the tooth from a design standpoint......they continue to be one of those few 'very special' amplifiers.
