There are actually 3 file types sold by Amazon: AZW, AZW1, and Topaz (TPZ or TAN). AZW is Mobipocket format and usually has no DRM. AZW1 is the DRMed Mobipocket format with one extra identifier added to the file header. Topaz is slightly different from the others and it has more features.
From my experiance, I think some AZW are DRMed, some are not (mostly the thirdparty production). And AZW1 and TPZ are the same thing. The topaz format is mostly used for tech manuscripts and the books with special formatting because it can use an embedded font and scanned text/equations.
