After years of intense research and development, the HD PHONO is finally available for discerning listeners of vinyl. It is the ideal complement to the HD range and the world-acclaimed HD PREAMP, HD DAC X and HD AMP monoblocks.Nagra’s first phono stage was derived from the Nagra IV-S reel to reel microphone preamplifier stage. It later evolved into the phono section of the legendary Nagra PL-P preamplifier. Ever since, Nagra has worked and improved that original design with the creation of the Nagra VPS and BPS, followed by the Nagra Classic PHONO released in 2020.The sound of the HD PHONO is unique first because of the quality of the Cobalt hand made input transformer. This transformer bring much larger frequency bandwidth and phase integrity compare to other transformer. So you can hear lower bass impact and speed in the lower spectrum and much more life like sounds presentation. All parts was selected by specifications and by hear for the best results compare to master tape.
