NO! Definitely NOT the same as a Dynasonic. In MY opinion, the Dynasonic is a VERY difficult drum to get to sound "right". I had a Big R one from the mid-70's and I absolutely hated it. The Dynasonic is not an aluminum alloy shell like (most) Supras do. The Dynasonic is a brass shell, I believe. Some people will disagree with me about this, but the Supra is heads and tails above the Dynasonic in terms of versatility, playability and availability. Plus, if you get a Dyna and something happens to break, then good luck at finding replacement parts. The Supra, on the other hand, is a much more user-friendly drum.
Some people LOVE the Dyna, though. It's all subjective. But, like I say, an Acrolite is basically an "Ugly Betty" Supra! ;) so you could invest a SMALL amount of money on an Acro to see if you like the sound (You will!). If you don't like it, then you still have a drum that can ALWAYS be re-sold for at least what you paid for it...or keep it and have that sound in your arsenal of sounds.
I play an Acrolite on my gig every week. It has had NO problems in over five years of weekly gigging. It's not a valuable drum, so I never have to worry about it getting stolen. If it does get stolen, I'll just buy another used one. No big deal. -Can't say that about a Dynasonic!Burger Kin
