“The bass was quick-footed, articulate and most importantly it conveyed a musicality that belied both its size and build. All I could say was DAMN! Ironically, instead of more powerful, the system appeared more relaxed and resolving – as if the added wattage aided in providing less stress and more realism. In a sense, it sounded as though the Heisenberg/Stern combo took full control of the massive YG XV’s many individual drivers and made them a single source. The very look and feel bespoke “state of the art” throughout while the sound is powerful and taut, yet elegant and ultra-refined. Voices hover above the floor at the right height and size but elicit a sense life that’s quite uncanny for a solid-state design. Music just flowed into this huge listening space in way that it had not in the past. It made the room seem smaller and more intimate. Weird. This made it somewhat difficult to concentrate on anything except the music. What higher accolade is there when a system can achieve that? I don’t know what else to say except that listening to the Audionet Heisenberg and Stern combination was truly an adventure!”

“We chose to listen exclusively to LPs for this audition. I got to spend the entire day listening to this remarkable system, and virtually every LP we played (I had a dozen of my own favorite records with me) left me astounded. From the moment the needle landed in the groove, the utter naturalness of the presentation became apparent. I was hearing subtleties of hall and performance ambiance that I’d never before heard in all my years of listening to this LP on literally hundreds of systems. Transients were crisper, more sharply and accurately delineated, tone color and texture were astonishingly accurate, and every aspect of the presentation was depicted with full, honest bloom, accurate weight, and ample body. Dynamic scaling was spectacular, and I was overwhelmed by the degree of ambient detail conveyed. Both of these characteristics coexisted in equal measure; neither showed compromise. An absolute revelation of the musicians’ spatial relationships within the soundstage and of vibrant, faithful timbre. And the rhythmic pace, the timing and drive of the music, had never sounded more frenetic! The Stern linestage and Heisenberg monoblocks push the bar to previously unattainable levels. In short, the combination of the Audionet Scientist Series Stern linestage and Heisenberg monoblock amplifiers establishes a new benchmark.”
