Slow adaptation of KT150 by amp mmanufacturers


I am surprised that more audio companies have not jumped on the KT150 by now. I know there are several manufacturers such as AR, Jolida, Primaluna, Icon and Allnic that have amps that are able to use this tube but I thought more would have by now.

The vast majority of reviews from people who have heard the 150 have been very positive. Any info on other companies who may have something in the works?

It looks like Tung-Sol is the only company that makes that tube. Plus it is alot more costly to retube. This could be the reason why! ????
Quicksilver has a new amp that uses the 150's, the Mono 120's. It's not on their website yet. Two per side at 100 watts. I've had them for about a month now. They sound gorgeous top to bottom.
One guy who keeps up with developments in the wonderful world of tubes is Roger Modjeski of RAM Laps. Before I bought any KT150 amp I'd talk to him about the tube---he is obsessive about tubes and amps being, before anything else, dependable.
Bifwynne You know, that was my first thought on reading this thread, before reading your post. Having installed the KT150's in my ARC Ref 75, I will pass this one by. I am still waiting for the local distributor to work out the cost of the SE upgrade without the tubes, which I have already of course.

My nerves wouldn't survive another long wait from ARC, whilst they work out the best way to maximise their income from this new commercial opportunity. Perhaps I'll let this bus go by and catch the new, newest KT210 tubes and no, I don't have any insider information that someone is working on them right now.
