Don't that v2 thing just irk the crap out of ya? For us thrifty, steady Eddys, that have everything planned out well in advance its the pits. I've walked away from companies that continually tweak or re-invent the same product, just too frustrating. If your heart is set on the Tanto, I'd check and see if any of the original designs are still available (might be discounted).
Keep in mind that eventually every piece you own will be replaced (supposedly with something better), either by the manufacturer or his competitor (unless you're a vintage gear lover). Doesn't mean your stuff suddenly sounds worse or that you can't keep enjoying it. Most stuff depreciates, the key is to "buy low" and get at least enough use/satisfaction to keep up with the depreciation (easier with some than others). Eventually you'll get to be an old stick in the mud like me and not want to change for the sake of change. Vendors hate that, that's why they target younger consumers.
Better to invest more time/money into the search by attending the RMAF! (Rocky Mountain Audio Fest)
Audiofests aren't the place to seriously audition, but you can rule out many contenders. Too busy, but wow, what a one stop shopping experience.
Warning - the mind/ear quickly gets overwhelmed at an event like this and accurate aural memory is very limiting (time/individual experiences). I'd take it in three steps: 1.) do a quick once over to find pieces you're really interested in; 2.) try audition no more than 3 - 5 pieces per day; 3.) go back and enjoy the rest of the show.
By the end of the show many vendors won't want to ship their wares back (especially floorstanding speakers) so you could score big savings if you hang around.
Let us know what you decide.
