Plenty of grunt

I am impressed at the sheer power of this amp. It’s 85watts but acts like double that. The duel mono configuration gives amazing soundstage. The dac and phono pre amp are both solid and will go a long way before needing to be upgraded. It is also stunning to look at. I have nothing but praise for this amp. If you are having a hard time picking between this and the m2si I would go for this every time for the duel mono design alone.
