    The sole REAL TRUE DAC for ANALOGUE listening
    amplification and filtering by sole transformers - no ative voltage or current amplifing stages, SUPER EPIGENETIC internal cabling - SUPEREPIGENETIC EXTERNAL connection toward AMPLIFICATORE VERO ASSOLUTO - remote control on motorized volume - no volume regulation by means of active devices - BLU POWER DAC power supply - two color oscilloscopes inside - input selectable from external PREPHONO VERO the sole prefono in the world with only transformer amplification from the input to the output - Outputs for BI-AMP toward 2 power AMPLIFICATORE VERO ASSOLUTO



    only transformer voltage amplification - no active voltage amplification with tubes or solid state devices. internal super epigenetic cabling

    The figure beside shows the phase response at open loop of the Burr Brown Operational Amplifier OPA 2604 that features a 0 dB bandwidth up to 20 MHz, one of the many used into the Hi-Fi applications (CDP outputs, amplifier inputs etc.)
    It can be clearly seen that already from 100 Hz up to 2000 Hz (red arrows), phase response vary up to 75°.
    This means that a tough delay exist between input and output in the more important range of the audio band, introducing distortion when feed back will be applied. This means also annoying material be introduced in terms of sound reproduction.
    A lot of intemodulation and temporal distortion will be generated when Feed back will be applied, because the delay is very important when there is a relationship between output and input.
    What does it mean to have a 100dB amplification, when maybe needed a 20 dBs or so and apply a 80 dB Feed back to make the amplifier usable?
    A transformer, gives the right gain without introducing intermodulation and temporal distortion because there is no relationship (feed back) between output and input.
    And in Royal Device, we do not use any form of feed back at all.



    Here follows what can be achieved with 5 transformers using ONLY ONE VOLTAGE AMPLIFIER into the last stage (power amp) without using any form of feed back.
    It can be possible to amplify from 0.2 millivolt (MC cartridge) up to 50-75 Watts channel and over with more than 30 possibilities of adapting the amp output to the load even in a SIMIL B-AMP manner.

    Alt det sinnsyke utstyret også putter man to gitarer og et trommesett rett ved lyttesofaen?!?
