Lo and behold, the piano of "Coils" by Serbian Jazz quartet Eyot from Drifters (a top tip for e.s.t. lovers) increased in body and moved forward. Even the e-guitar and percussion transients had more spatial profile for higher stage presence. That the Simplicité or S/PDIF differ from a laptop or USB I'm used to. The notable if not dramatic gain in spaciousness I'd here lay at the feet of the loaner's various inputs. Now a few words on connecting analog where the signal faces A/D conversion first. This extra stage telegraphs as a minor dulling and lower drive. "Treble brilliance and transparency are reduced, stage dimensions shrunk a bit" is how my notes put it. But the core virtues of neutrality, bass power and fatigue-free listening continued at a high level. The analog input remains a valid alternative even if the speaker's top potential is best pursued with already digital sources.

Again, fans of ultra-spacious sharply sorted soundstages should pay close attention before deciding blind. Particularly in the milieu of small monitors many boxes specialize in this discipline at a higher level. Those with other priorities meanwhile should delight in the areas where the small A-300 approach the extraordinary. Nubert's engineers have solved the conflicting goals of LF reach, SPL stability and box size to a really brilliant degree. Even fans of tower speakers (yes, it's true!) should give these a try. What's more, in this sector you'll be hard-pressed to find another speaker which less meddles with the tunes. Well-balanced tonality, impeccable dynamics and satisfying resolution make for a pleasing non-fatiguing experience. Trim by way of four i/o options, A/D conversion, digital-direct drive and volume/balance/input control by remote nearly make the nuPro A-300 into a complete system. At this quality you nearly couldn't get there for any less.
