IME (I've owned deCapos and Parsifals) the Verity and 3a "house sounds" are very different. Verity speakers are voiced with a mid-bass hump and falling response thereafter. Th deCapo is much flatter, but rolled at both extremes. The net effect (to my ear) is that the deCapo is neutral, revealing, and a touch "dry". The Verity is more "musical" (that is, bad recordings tend to sound better on the Verity) and punchier.
Disclaimer: My experience with 3a is limited to the modestly priced deCapo while I've heard most of the Verity line. My observations are undoubtedly colored by my ownership of the much more expensive Verity P/E, but I'm pretty comfortable with the general observation that the 3a will likely be "drier" and more neutral, while the Verity will be punchier and more forgiving.
