Au­dio Tech­nol­ogy Switzerland has an­nounced that it will soon re­lease the Na­gra HD Preamp, which it claims is: ‘ our most am­bi­tious preamplifier ever.’ The Swiss com­pany’s an­nounce­ment comes ex­actly twenty years af­ter the re­lease of the com­pany’s first con­sumer prod­uct, the Na­gra PL-P preamplifier. Prior to that time Na­gra had been man­u­fac­tur­ing prod­ucts ex­clu­sively for the pro­fes­sional record­ing mar­ket… which it had been do­ing suc­cess­fully for more than 40 years. The PL-P preamplifier was a Class-A tri­ode-based line and phono preamplifier. ‘In many re­spects, the HD Preamp’s de­sign started from a blank page,’ said Matthieu La­tour, of Au­dio Tech­nol­ogy, which man­u­fac­tures Na­gra in Switzerland. ‘ Ev­ery as­pect and step in the de­sign process in­volved re­search to find the most el­e­gant so­lu­tion to ac­cu­rately and faith­fully con­vey the mu­sic from the source to the am­pli­fier. As a re­sult, the HD Preamp, which like the PL-P is also a tube de­sign, in­cludes sev­eral patent-pend­ing tech­nolo­gies that take the mu­sic lis­ten­ing ex­pe­ri­ence to new heights. It is the per­fect part­ner for the HD DAC and HD Amp.’

The valve-based HD Preamp a dual-mono de­sign with a sep­a­rate power sup­ply (us­ing Super Caps) built around Na­gra’s ‘vir­tual bat­tery’ tech­nol­ogy that pro­vides su­pe­rior re­sults com­pared to a con­ven­tional bat­tery with­out the in­con­ve­nience of deal­ing with charg­ing time and bat­tery life. ‘ Just as the PL-P made use of bat­ter­ies to iso­late the unit from ex­ter­nal in­ter­fer­ences, the HD Preamp’s power sup­ply uses a unique vir­tual bat­tery tech­nol­ogy,’ La­tour told Aus­tralian Hi-Fi Mag­a­zine. ‘ One of the con­se­quences of this su­pe­rior sup­ply is that the noise floor level of the preamplifier reaches un­charted ter­ri­to­ries: the low­est ever mea­sured on a Na­gra prod­uct.’

As a trib­ute to Na­gra’s leg­endary recorders, the HD Preamp also fea­tures a ‘mod­u­lome­ter’, a cus­tom-made meter that Na­gra says is faster and more ac­cu­rate than a tra­di­tional VU meter and an im­prove­ment on the mod­u­lome­ter fit­ted to the orig­i­nal PL-P.
