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

Gary (Hifigeek), does the G series employ some new technology? Or is it some type of super reference amp designed to mate with the Ref 10 and Ref Phono 10??

I just started a new thread where I report on ARC's new G series. I have a URL x-ref to where you can see pics and prices.

It's a new "higher-end" series which is priced higher than the "normal" Reference product equivalent analogues; namely: the Ref 5 SE and Ref 150. There's also an integrated version of the Ref 75. The G series is really gorgeous and uses the new KT-150 power tube.

Looking forward to reading and learning more about the G series.

I believe the pic on the web site is the G integrated amplifier.

Gary, TAB says the new models "are 'reimagined' versions of current models." Do you know yet if the G series incorporates new or improved technology, other than the KT-150 tubes.

Just speculating of course, but if the G series is essentially repackaged existing products, the use of KT-150 tubes may permit one or both inferences (or surmises) that (1) the existing product line can handle the tubes and (2) that ARC completed "life testing."
