New KT150 tubes?

Has anyone any experience with these pretty new tubes. There are already one or 2 amps I know of, that use them. The review of one of these amps in a UK magazine suggested they were a little warmer and more natural sounding than the nearly new KT120's

The article also suggested they were a straight swap for KT120 based amps, with no adjustment necessary. They are more than twice the cost of KT120's, but still not too costly compared with NOS tubes. I know changing from KT88's or 90's to 120's. did require some amp modification. I have an ARC reference 75 and might want to try the new tubes at some point, ARC don't seem to have a customer E-mail service, to ask the question

That info is from here:

I am sure tubes from ARC will be a premium but probably matched better.

My Jolida Fusion 3502 , not the S model  has much more premium parts
And has many upgrade options.
I use all 19 50s preamp tubes Big upgrade and  switched out the very sweet EL34 
Power tubes 50wpc.  Now the KT 150 tubes up the power to 80 wpc.
The midrange is almost as sweet as thd el34 ,but better by far in the midbass low bass dynamics much more slam soundstage depth as well as size is bigger.
Online a matched quad  $270 delivered. Fantastic tube. If using a smaller or older amp check first. Upgrade to bigger power supplies if possible to optimize for this tube.
