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

Such a rebel! Especially when you consider that no amp has ever been reported to have blown up from 120s or 150s.

Dakingat55,

Please keep us updated on how your amps are doing with the KT-150's. I'm too chicken to try them right now.

Thanks!

Joeinid just want you to know that I'm having no issues at all.yesterday I had a lot of my audio friends and audio business contacts over to here the magic thats going on in my system.The amps were running for 5 hours,and pushed them to their limits a lot off that time,again no problems at all.everyone who was there had the same comments ,ie,best dynamics I ever heard ,totally grain free,the instruments,sound so full and rich,imaging and stage depth huge.I can honestly say going from kt120's to kt150's is the single biggest improvement i ever made in my system.ill try keep you up to speed thanks David

David,

Thank you again. I appreciate your input very much and I am so happy you are enjoying the new sound. I have the ART monos and an ARTsa. I was also told no on the KT-150. I can't imagine them blowing up the amps but may affect ultimate longevity going forward. I have a small integrated that will accept KT-150's and plan on hearing them in that one first. Thanks again!
