Been listening to the hiraga amp for past week or two and have to say, it is performs very good for a SS. Better than what I have experienced in the past with SS gear (high powered pure class A units included). Sound has great clarity and preciseness. Imaging is rock solid and resolution is extreme. Doesn't have any mid-range 'warmness' that I am used to and often enjoy with some of my past valve amps, but doesn't mean it 'hides' any of the midrange detail.
Very promising and quite glad, as I have 3 custom 8watt hiraga le monstre's poweramps being built to run the 3 horn channels of my setup. With the bass channel, still interested to compare something like the Naksa 70 with the 20watter hiraga to see what the differences will be.
