Xri16 just heard the KT-150 the other day on a Octave RE-290, compared to the KT-120 is like comparing a Rolls Royce to a Toyota. Surpasses the KT-120 in every way. A more extended bandwidth with a blacker background, bigger and deeper soundstage, a much fuller sound with a lot less grain. Once you hear this tube, all the other tubes just simply became obsolete, a perfect match with the current Genelex Gold Lion input tubes, in this case the 12AU-7's. Can't wait for them to issue a Gold Lion version of this tube.
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
