Just got these yesterday and got them re-headed and set up today. The thing I discovered is that even those these are smaller than my Ludwig Classic Maples, they have that sound, and they sound bigger than they are. The bass drum sounds quite big for a 15x20. I'm really happy. I'll post a video or something once my recording studio gear shows up.
But Bermuda is right, if you're looking for a nice solid maple kit built here in the USA, you cannot go wrong with the Ludwig Signet 105. Mine here is the Gigabeat kit with 8.5x12 tom, 14x14 floor tom, and 15x20 bass drum. I added my 5x14 Supraphonic to it. I installed coated ambassadors on top and clears on the bottom. The bass drum got a power stroke 3 with the stock logo head on front. It sounds great and is super light. These things SING!
