Smoffat, let me be clear. I am not interested in ARC's precious cache of KT-150s. I understand that ARC will charge $200 a tube. I have no intention of paying $1600 for 8 tubes ... period. Instead, I will probably buy 2 quads from Upscale Audio. Upscale is charging about half that.
I only want to know one thing and one thing only. Will the KT-150 damage or prematurely age the Ref 150? That is it.
Oh ... and as far as Tsushima is concerned, he is in no position to know the answer to my question. Just because the KT-150s presently "work" in his Ref 150 is not responsive to my question.
OTOH, if I learned that the innards of the GS-150 were identical to the Ref 150, then I could fairly infer that the KT-150 would do no harm.
