Dan is the expert on what goes into making a great converter, however I'd like to point out some of the economics which may be involved in your Lynx One.
The first thing to understand is how little difference in cost makes a big difference in retail price on many products.
If the product is sold to retailers through a distributor (the norm for products with a fairly large market) then the distributor probably pays only 20-30% of the recommended retail, so for every $5 in the list price, the manufacturer might get only $1.
Add to that the fact that the manufacturer needs to make a profit, let's say 25 cents in every dollar, then you might be looking at a situation where for every 75 cents extra cost to the manufacturer (be that an extra component, manufacturing cost, or extra engineering time in the design) you see the list price go up by five dollars.
So, basically, small difference in cost at the bottom of the chain = big difference at the top.
Now there's the question of what those differences might be...
better quality components
more components
design time
layout time
more expensive PCB manufacturer (e.g. more layers)
test equipment and facilities
design software
and that's at the low to mid range of the market I'd say.
At the higher end there might be a smaller percentage margin from manufacturer to customer (smaller markets mean that manufacturers are more likely to deal directly with retailers), but you'll be looking at even higher quality designs, which take longer to get right and are more expensive to build (add a high quality power supply and a DSP to do the downsampling for example), all divided across a far smaller customer base.
