Hey Dusty,
I am sorry - I didn't meant to sound hursh in ANY way. Just to let you know - I am an investment banker and financial analyst specialized in electronics.
Our statistics shows that for small electronics (in our case DACs and phono stages) the optimun price that will generate the largest profits is, very exactly, $548. Any lower price we make you loss additional profits per unit, and higher price will make you sell less units, resulting on the long term in smaller revenue. This is what we call "price elasticity".
Other then that, let me show ALL my respect for the fair prices and good products that you've put in the market so far.
Notre respect.
PS Now, if the price will be $600, instead $548 that shouldn't hurt you sales too much. But just to let you know - our estimates shows that your total revenuews might decrease by 18.9% due to this "small" $52 diference.
