    This is an astonishingly good amplifier. no bells or whistles, but great engineering, power and a beautiful sound. Looks great also.
    I am driving a pair of PMC Twenty5.23 floorstanders, fed by SOtM sms200 ultra neo streamer and Chord Qutest dac and the authority, power and detailed sound, plus the lack of tiring edginess or brightness is simply captivating. I haven't stopped listening to it since getting it.
    The internal dac, though 'only' 24/96 has a brilliant and dynamic sound, don't be fooled by it's seemingly low resolution. It is my preferred dac for most listening. I only need the Chord for CD, TV etc as the amp has only the USB i/p for digital. Highly recommend this amplifier.
