Frustrating is right.
I will start with I have not heard KT150's yet, and don't own an Audio Research amp...
I do have an amp that will work with them however.
But I will say this thread with Audio Research probably went way over the top with ARC owners being way too concerned, and way less about the KT-150.
I believe Audio Research is probably the biggest Tube manufacturer still in the united states, maybe the world.
My answer to why Audio Research has not "Approved" this tube is by far simpler than what is being talked about here...
They are afraid far less about the KT150 killing YOUR amp than they are about it Killing their Current inventory when nobody wants to buy the 10,000 or who knows how many KT-120 matched tubes they already have in inventory ready to go!
As soon as they say 'GO' on the KT-150 officially on the website or wherever who is going to buy all those already KT-120 AR certified sets sitting on the shelf?
Just something to think about.
