You may find the answer in my review.I've got an M17 right now. I love the sound and the power (I have HD600s and LCD-2 Classics they drive very well in DC mode). However, I find that I don't really travel with it, I'm using it on my desk most of the time. I feel a desktop unit would be easier to use on my desktop (geez, who would have guessed) with access to dials, controls, etc. I would buy a K9 Pro ESS, sell the M17, and use the residuals for some new cans or something.
My question is, since they have basically the same hardware, do they sound the same? That is, if I enjoy the sound of the M17, is that what I'll get with the K9Pro ESS? I read there was some difference with the K9Pro and the M17, but I assume that's because of the different DAC chip manufacturers.
Thanks!
