Coincident? The same time you're introducing your first DAC/Amp, you're also introducing you're first two IEM's optimised for use with amplifiers. Marketing on his best, but almost on a level that makes me belief that RHA beliefs that ALL customers are brainless. Don't get me wrong, I'm own several RHA products and I love them, but will considering now to buy more from them. I'm a RHA costumer from the beginning when I was believing they do great stuff out of love for the IEM community. Now RHA is just after profit based company. Sade day indeed.
