The 600i is a great amp for the price when used in balanced mode, but compared to the Taurus MKII it is not a contest. The Taurus has much more energy, it is cleaner, tighter, much more spacious and more detailed. The 600i sounds hazy and two dimensional in comparison especially in the bass and treble region. The bass control the Taurus offers leaves the 600i in the dust. I do prefer the 600i to some other amps like the LP or even the Pro iCan but the Taurus for me is next level and pretty much end-game performance in solid state amps.
