I guess, in theory, he could have a "generic" tour model...but then again, how are people going to feel about eating two way shipping costs of $500+ if they don't like them....let alone all the finger pointing that could very well occur when a 110lb speaker gets dinged, even slightly, by the shipping company
Volti already offer an unfinished pair of the Razz at a significant reduced price (which is a really cool idea). If the 'touring' model was just for potential customer in-house demos, dealing with marks or dings wouldn't be an issue, and if you like it, you pick your finish (if you want a finish) and order new after you know you like it. Round trip shipping costs for large speakers does seem like an issue though. I personally wouldn't mind paying a demo or rental fee as I listen in my system before I return it or pass it on to the next person on the list. To pay the shipping fees, one would assume you have decent probability of purchasing and the manufacturer direct sales model is offering a price that makes it worth while...
I'm done buying speakers without a return option for scenarios where I cannot listen to it ahead of time. I purchased a pair of new Magico S series speakers from an out of state dealer with no return policy and had never heard Magico but was interested after reading the many positive reviews, and I didn't keep them long term as they were not a great fit for me.
I've owned Forte IIs and Cornwall 3s, so Volti has definitely been on my radar for a while, but I've never heard a pair and live a long way from TN.
