Even for an audio veteran of 50-odd years’ standing, surprises still occur. The PREAMP II-S emerges as one of the most ideally balanced exemplars of transistor-biased tube technology that I can recall, certainly at its price. Were I well-heeled and in need of a control unit, unwilling to forsake my full-on valve leanings, this would force a rethink. It’s warm, open and as silent as needs be. It just may be Nagra’s new ‘sweet spot’.
