ITron is solid state, perhaps the best implementation of this, but it remains solid state.
IMO, the iTron is not the last word in solid state amps for AGs. More emotional and liquid SS amps like SIT4 and Bakoon are other smart options, of course, for those who still want to have SS with AGs but with SET-like warmth and tonal presentation.why they have championed SS with their speakers I will never understand. Engineers mindset rather than listening perhaps??
However, if one doesn't care about pure liquidity and organic warmth and instead seeks extreme clarity and neutrality and as well as superior control and extremely low distortion (the advantages of current amp), the itron could be the best option for them.
I think it all comes down to preferences.
