I am currently using the Studio IV and still have the Studio V's which I bought several years ago. The monoblock Studio V's have a bit more 'heft' and bass as you would expect, but the IV has, perhaps, a bit more focus, though I haven't done a lot of back and forth comparisons.
I was auditioning a number of used amps for a second system and the Studio IV was far and away the best I had heard in the $500-700 price range. At the moment it remains in my main system as I focus on other upgrades.
