Guy, I'm not Danny, but I think you may have misunderstood his reply. . .
Your question (if I read it correctly) was:
"Which of Danny's kits offers the most/"best" sound quality for the dollar?"
Then, you asked three follow up questions:
"Which tweeter Danny is offering is the 'best'?"
"Which enclosure type among Danny's kits is the 'best'?"
"Which configuration of subs - open baffle V1/V2 or sealed Rythmik F12G - is the 'best'?"
To your first question, I DO NOT think Danny meant, "They're all good! Just pick one." I think what he meant to say (again to answer your first question) is that at each price point (dollar amount) each kit is sold for, it is the best design he could create using the outlined parts and enclosures. Meaning, every kit he sells regardless of price (because there are many "kits" he designs that never get sold because they do not meet this criteria) is the best sound quality for the dollar AT EACH PRICE that he can deliver.
So, maybe put another way, what he is saying is that it really is just up to you to decide on how much money you would like to invest, and for that amount of money - no matter how much that is - you will be getting the absolute best sound quality Danny can deliver. It is less a question of which speaker is "better", but more a matter of how much you want to spend. Further, in saying the more you spend (more expensive kit), the more "sound quality" you are going to get, what is being said is that you will subjectively get "more sound quality" the higher up the price scale of kit you go.
In other words, for example, it is not like the N3 kit is actually "better" than the V1 kit, even though the V1 kit costs more; you just need to decide for yourself how much "better" is worth your dollar to invest for you to be satisfied. In short, pick the price you want to spend, get the most kit you can for that money, and be satisfied knowing that for that amount of money, Danny could deliver no better.
Danny's last (first?) piece of advice for you is probably the most direct - to get the ABSOLUTE MOST out of whatever kit he has to offer, he is suggesting that you have your builder construct the cabinets just as designed. Anything other than (minor) artistic variations means you are maybe not getting ABSOLUTELY EVERYTHING in sound quality Danny designed into the speaker. Building kits is fun and trying out new stuff is fun, too (I did the same things as you in the past - see my sealed paudio coax speaker here on the boards), but if you are looking to find your "last speaker" and spend the least amount of money to get there, going with the design as written out will get you there a lot faster for a lot less money.
Using this knowledge, your thoughts on investing your money wisely, and looking at what you already have, I would suggest the following, assuming you can place the speakers three feet out into the room (don't worry as much about small rooms with these open baffles, other folks here on AC have had great results doing just that):
Rebuild either the V2 (using parts you already have) or order a set of the open baffle 12" servo subs and amps from Danny and rebuild your V1 - either way, have your builder build the cabinets just as designed.
Ask Danny about, and have your builder add some mass to the cabinets your F12G subs are already in. Put these subs in the back of your listening room along with the V1/V2. Adjust everything to taste/measurements.
This will use the most of what you have, get you the most speaker for your dollar, let you use your nice amplifier easily, give you enough speaker to maybe play with upgrading everything else in the chain over time while still seeing improvements/results, and put you nearly to the top of the line in the kits Danny offers.
Then, later, have your builder construct Danny's N3TL cabinets as designed and build out the N3TL kit for a second set of speakers for your bedroom. At some point, when or if you upgrade or change your amp out for something else, your current one would make a fine pairing for very nice music in your second system.
In the end, what I'm saying, from the best I can see based on reading your past build threads, is that it looks to me like you have most of or all of the parts for an absolutely AMAZING system already in your hands; you just need to put the pieces together in the right configuration to make it happen.
Hope this helps. . .
