A formidable phono preamplifier that can be unreservedly defined as the new frontier in vinyl record playback. To achieve this, it includes some of the substantial technical innovations incorporated in the Reference 6 SE line preamp in a configuration featuring vacuum devices, specifically six 6H30s in the audio stage, plus a 6H30 and a 6550 in the power stage, the second assigned to regulatory tasks.
For its part, management through an effective menu system allows the user to control functions such as automatic shutdown, gain and load impedance settings, the brightness level of the function display, the equalization curve and the accumulated hours of use. through the vacuum valves. Two sets of unbalanced inputs allow you to connect two turntables, while balanced and unbalanced outputs and RS-232 and IR jacks are available for additional control options.
