Nagra HD PREAMP HV appears to be a highly attractive and engrossing high-end audio component due to the many questions and feedback received. It is a magnificent tube preamplifier with impressive technical specifications that easily compete with the best solid-state preamplifiers in terms of specifications before even entering into the sonic realm.
As you could see in previous articles, I am seriously investigating the HD PREAMP HV tube rolling compliancy, and as requested, I have taken some interior shots, also from a bird’s eye view.
