I agree, that is interesting. I have a thread running about the KT-150's and the current reference line. ARC is evidently running an endurance test to see if swapping out the 120's and 150's, is feasable.
All I would say about the integrated GSi75, is that I compared the Ref 75 with the current i75 integrated and it was no contest, the standalone amp was, in every way better than the integrated. Now I know the GSi75 is completely different and if it is a reference product, which the current i75 is'nt, it may be a lot closer to the power amps. When it comes out, I would urge anyone considering it, to compare with one of the Reference power amps, before commiting to a purchase. I notice there is no equivelant to the current Ref 75, the smallest Power amp in the G series, is the 150. This may reflect that the 150 valve is more powerful, but if there is going to be a reference G75 or 100,power amp, it may be worth waiting for. I am not the only one, who thinks the current Ref 75, is a nicer sounding amp than the Ref 150, with suitably sensitive speakers.
