Personally, I am more irritated by the pricing being driven by what the market can bare vs. being based on the cost of bringing it to the market + "reasonable" profit margin to support the company. In the case of lcd3, I was very skeptical because there was no clear explenation on the cost other than "It will sell...".
There have been clarifications since, such as extensive r&d, more intricate driver design. If really the cost is driven by this effort, then we should just applaude because Audeze is helping to raise the bar for headphone sound quality. Looking at it as a "glass half full", I interpret the increase in price as a consequence of spending more money on development because the market is maturing and thus being ready to pay what it takes to get the ultimate system.
Looking at it as the "glass half empty", I can't help but feel that the temptation to maximize profits must be significant. After all, almost everyone is happy to make more money if they can... Well on the customer side, I also work very hard to make the 2k required to get such headphone so it is natural I want to trust I am not being significantly overcharged... The design of the lcd 3 not being drastically different from the lcd 2, makes it a bit hard to see where this extra money is being necessary. Maybe the company is quickly growing and the overhead costs spiralling?
In the end, the evolution of prices is probably due to a mix of the above. Certainly, time will tell if Audeze made the right move on releasing this headphone at 2k...
For the talk about the smaller incomes being excluded from high end audio, this may indeed become true on the first hand market, but you should see some good discount on used lcd 2 in the weeks to come ;)
My 4 cents (it was a nightmare to type this on my iphone 4, awful lag, so I deserve more than 2cts ;) )
