RE: ...$30K...
You'll find this with just about everything. Dude with expensive, sometimes hideously expensive item questions the validity/effectiveness/worthiness of the cheaper but well made purpose built item. It can't possibly be in the same league, somehow isn't suitable for it's purpose because it isn't "engineered" to the same standards as the more expensive item. Sometimes that last bit has more to do with over engineering and attention paid to things not conducive to the actual performance of the item.
I'm not against very expensive items. If I could swing it, as in not worry about $30K expenditures, I'd probably be looking in that range for my audio gear fix, but I'd also be very quick to get the cheaper item if it performed better for the money. All things being equal or slightly in favor of the more expensive item, I'd be looking at other attributes not related to sonics for my consideration. That's just me, and I won't say that all who spend a lot on speakers hate on the more budget gear and I'm also not of the opinion that the Moab is somehow better than the majority of $30K speakers, nor do I think that because a speaker costs $30K it must be good, but I do think it had better be :).
Given the broad range of products and possible combinations, and ears, don't forget the ears, it's hard to say what's really better amongst items at a particular performance level. I will say that after a lifetime of being exposed to live music, playing music, being in a choir, listening to various rigs at friends, family, stores, and at home over the past forty something years I think the Moab gets everything right to my ears and more than one should reasonably expect for $4500. To my ears, it becomes a question of how much more of it do I want, who makes it, and how much does it cost? So I think the Moab simply hangs in the playground of speakers that at the very least don't do much if anything wrong.
I enjoy engineering, I like seeing the different ways one approaches and solves a given technical problem. But if looks aren't the issue then it boils down to which design delivers the best result for the money. Sometimes you just don't have to spend too much to get there.
