I'm a Paradigm Studio v3 owner and also a Sierra 2 owner (not tower). When the Signature came out, I went to listen to them and was blown away by their sound, but their price tag was way outside of my budget. When I finally did upgrade many years later, I went with the Sierra 2 since others had compared them to the Signatures. The Sierra 2 are incredible speakers and the RAAL tweeters sound great with music. Are they better than the Signature? I'd say they were better in some ways (voices, instruments), but the difference wasn't night and day to me.
If I were starting from scratch, the Sierra 2 are the better bargain. If I already had the Signature, I wouldn't have bought the Sierra 2. If you don't have an Atmos setup, I would highly recommend getting 4 of the Ascend HTM-200 and using them as ceiling speakers with your Signatures.
