The Burson Timekeeper 3iR is just wow. I have not heard the Kef R300 so articulate and clear. There is more of the bass that I did not know it had. The mids has been more pronounced. The highs just a little bit more bright but not harsh. I just have it hooked up to my tv via toslink cable. The fact that this little all-in-one still has Bluetooth connectivity, RCA input, and a sub-out is great. I do not have any fancy cans but will definitely try it out when there is more funds. Anyways, what an amazing product that Burson Audio has here.
