Staying with this lens analogy for one moment (yes, it's a very bad one)
There's a reason why good lenses cost so much, and if you ever saw how much precision engineering goes into them you'd also understand. You have multiple glass elements of which some move when zooming or focusing and if anything is a fraction of a millimetre out then the lens simply won't function correctly. That takes some severe engineering ability and production costs.
The Poly on the other hand, from first glance, doesn't actually appear to contain anything that can't be manufactured by a Chinese or Taiwanese facility for a couple of bucks a piece from off the shelf components, or even as a single SoC (in fact I'm sure you can purchase an off the shelf SoC that already does everything needed here). OK there's firmware development and app development to be considered, and then the cost of the Aluminium housing. However that does not make the value of the Poly anywhere near the price being asked for it. In fact I'm sitting here confused as hell as to how this little add-on could possibly cost more than my iPod Touch 128GB which packs in way more technology than it would appear the Poly does. There is, of course, economies of scale to consider, but even so the price of the Poly simply does not compute. Maybe the Poly contains some secret source in terms of upsampling technology, but hang on, we've already been told to leave that to the Mojo anyway.
Now I'm in the fortunate position where I don't actually need to complain about the cost of this device - in fact I'm slap bang in the middle demographic of what I would imagine a typical Chord customer would be. However, I look for value for money in the things that I buy, and I'm really not seeing it here. As an aside I don't see much, if any, value for money in "Summit-Fi" in general, but that's another discussion.
I know that a lot of people here had to really save for a Mojo, a marvellous device I might add, but I can't help thinking this Poly is just price gouging, and has really annoyed a lot of people who did have to scrimp and save for a Mojo.
Sorry Chord, but I really hope some Chinese manufacturer comes along and provides the same or similar functionality for a fraction of the price. Given that the Mojo is a class compliant USB audio device it would be child's play for the Chinese, or anybody else with good electronics knowledge, to do this.
