Questions on KT150 tubes


Does anybody here have experience using that tube? Can you tell me how it sounds? I have a Primaluna DiaLogue Premium HP and it can use them but they aren't cheap. I'm running the stock EL34s and LOVE it but seems like this tube is all the rage. The Primaluna is unbelievable for its tube magic as-is. Also I wonder if the KT150 would last.

Also the best places to buy them. Not the cheapest. The best quality.

Just googled ~~KT150 Review~~ and brought me here, read through the posts. 
Only confirms what i figured out on my own reserach independent of the comments/experiences posted here.
I listened to the YT vids of the few 150's uploads( sure sound is compressed etc) still I can detect  that the 150 is the tube i want to roll next in my Defy7. I bought it with 6550's and never listened to it with that tube, as i had no preamp,,,yrs later i boughta  pre and decided to get the Defy up N running with KT90's, as i recall fond memories of that tube in my jadis Orch Refer,, the EIKT90's are over rtaed as mentioned by a  jadis expert here on audiogon.
So I just sold off at 1/2 price the 12 EHKT90's and am running the KT88, labeled ARC,,,a  bit superior to the 90. So I am looking for a  bit more soundstage for my full orchestra muisc.
I thought maybe the KT120;s..then I thought through a bit more carefully, as i do not want to make  yet another costly error,,,so i thought ~~~why should i even consider the1 20's, when fora  bit more i could get the 150's. 
After hearinga  few YT vids of the 150's. its certain its my next upgrade.
Sure the 88's are really nice. But since i am looking for ~~Nirvana~~ the 150 will voice the Defy's raw power and dynamics more than the 150's smaller brother, the 120.
The prices are stable at near $400 Sextet from 1 ebay seller. 
btw I have my cayin cd17 Mark1 in the shp/installing twenty  M SGO caps, the white  casing. Can not afford the much larger sized  Supremes, nor would they fit,,,,,even the whites are going to be jammed in/but doable,,,I will return to the shootouts twix top dog AX's and also  the AU's vs the E80CC's. ...back to subject,
The KT150;'s. ,,,,,,you do not see any used/good bargains on ebay,, = ~~a  keeper~ = ~~A winner~. could we say the 150 tube is ^^almost^^ approaching a  single ended tube sound, the 300/805/845 sound imaging?. 

Just googeled  kt150;s. seems someone  with a  Conrad Johson rolled to KT150s with no issues at all.

Right now i had him bias for kt90's and sold those off, and now running kt88's with the same bias point as for the 90's.. I did not want to spend another $250 for rebiasing a  tube just a  hair fraction off from the previous tube,,now with the 150's, i can see the bias as practical vs the current  kt90 bias point. .

Thanks for the post, . 
I have a  good local tech geek who can advise me about employing the kt150's.
as you know jadis builds high quality trans, i do not run hot volume anyway. 
I plan to purchase the 150's,. if they run hot,,,for whatever reason,,i 'll go back to 88's. 
that will be  a  late 2020 project. 
i'm not worried about damage to the trans, as i say i listen on low gain,,
