Audiofankj, I would discount any opinion given by a dealer - even the most enthusiastic have an agenda around profit, inventory and what's in fashion (i.e magazine reviews, forum raves, etc.)
I can add support for the Dynavector range - I recently bucked the current fad for all things Zyx and bought an XX-2 which is a wonderful performer. I struggle to imagine how the Te Kaitora and XV-1s could be better.
Larry, I don't think Raul is bashing Zyx - he's consistently pointing out that there are better performing, albeit less fashionable alternatives available for the same money. I have to say the he's right.
I have only heard an Airy 2 and on some program material the bass extension was lacking. This was in the UK dealer's own system which he claims to be very revealing of flaws. My take is that if that's the best he can get the Airy 2 to sound then it's not good enough and the cheaper (by £500 in UK) XX-2 beats it.
If you think about it, it would take a brave person to post here saying "I got carried away by all the euphoria about this cart. It doesn't sound that great in my system, I wish I'd bought something else." Far more likely they would keep quiet then sell it on, mimizing their loss.
So it's inevitable that the cautionary and critical comments will come from non-owners - that doesn't mean that those comments should be disregarded.
This forum would be a pretty boring place if participation was restricted to members commenting favorably on the equipment they currently own.
