look forward to the review, use plenty of Nak in the 80's and early/mid 90'sThe company is not the same from 30 years ago, sold within the last 5-6 years to the new owners. It seems they have been trying to bring it back from the dead with some nice offerings as of the last 2 years. The amplifier uses the 12AX7 tube which has been around forever. If they ever go out it should be easily replaceable and even improvable. So far I have been testing it against a ground zero ref and Focal Dual Monitor. It can hold its own. I will write a review once I have some time. Been working non stop lately.
