The system I used for this review was not a state-of-the-art, no-expense-spared setup like the systems in an active audio show display. But I’ve spent quite a bit of time fine-tuning my setup to achieve an accurate, musical sound that’s also revealing enough to expose this Nagra preamplifier’s true sonic characteristics.

The review system was in a dedicated, acoustically treated listening room, with two power lines devoted to it that ran directly to our home’s circuit box. Not only are there acoustic panels lining the front, rear, side walls, and the ceiling, but there are also shelves filled with LPs lining many of the listening room’s walls. The room was painted with Sherwin-Williams “Sky Fall” blue. Psychology Today claims that blue affects people cognitively and emotionally, reducing stress and lowering heart rates, among other benefits.
