Just got my KT150 tubes for my ARC REF75 and it was a plug and play install. No issues, at least day 1.
At this point I cannot comment on SQ as the tubes were right out of the box, all matched, but nothing broken in, so I am not in a position to comment other than to say, there is definitely more kick than with the KT120s-sounds like a much more powerful amp. Whether that turns out to be a good or bad thing we will see and refuse to judge at this time. Different isn't always better.
Curious if anyone else has made the plunge to these relatively new tubes and what your feelings are.
