Description

NEW - Shinobu Karaki-san's new Masterpiece , Aurorasound VIDA Supreme 

Taking advantage of VIDA sales in world wide and many customers feedback, VIDA-Supreme is designed for much high-end analog audio-phile.

The VIDA Supreme brings the e dynamic, the transparency and the fine detail of a high-end active phono stage with the kind of natural sound, fluency, musicality of a step-up passive transformer.

State of the art semiconductor design (LCR-type network), innovative technology and  modular design combined with old-world craftmanship makes this phono amplifier outstanding in many aspects, substantially surpassing the original and highly-decorated VIDA.

VIDA Supreme standard configuration. Standard equips two input, MM and MC low impedance.   Most of all modern MC cartridge is low impedance, under14ohm.  If you need more MM or more MC and/or more functions, please see the section "Personalize your VIDA Supreme" below to add the option cards in open slots.

FAQ about VIDA Supreme 

1.What is LCR type equalizer? Why is this good?

LCR is stand for L=Inductor(transformer), C=Capacitor, R=registor. Three component consist a RIAA filter network to make equalizing the RIAA curve signal to flat, that is recorded on vinyl disk.  Most of all phono stage amplifiers in the market use C and R only, not use L. Because L is very expensive parts and L is not easy to keep same value of inductance factor in mass production. Aurorasound requested Lundahl , Swedish famous professional audio transformer manufacturer, to develop special L to keep high quality and reliability to satisfy phono stage technical requirement.  Sound character and advantage of LCR phono is,  low distortion and high resolution in low frequency range. This is good for spacial 3D sound images. Rich and strong mid range, stable and delicate in high range, good for Piano`s high note or JAZZ
top cymbal.  LCR is supreme solution for phono stage amplifier.

2. Which is better, MC step up transformer or MC Head amplifier?

This is depend on each people choice. Somebody loves transformer sound, other prefers semiconductor HEAD amp. Transformer is very low noise due passive elements without power supply. HEAD amp is wide frequency range and high sped sound, and capability of fine adjustment with cartridge impedance.  Which is better.. ?   No.   Which you prefer ? is correct.

3.What is"Inverse RIAA"?

Many people has question what is this ?   Inverse RIAA changes CD/DAC  signal to analog cartridge signal that is RIAA frequency response.  Then output through phono stage amp. Of course, frequency range , SNR, and THD are worth than CD direct to Pre-AMP. But, inverse RIAA makes sound changes to much middle rich and condense the core of music. Digital sound is changed to what we called “analog sound” through filtering process. Some people do not like digital, they loves analog very much. This card is for those analog fetish people. This is option.

4.How to insert the option card after purchase?

It is easy to add new option card by yourself. Power should be turned off, and open the check window on top cover. Then insert the card carefully to the connector. After that, fasten the thumbscrews to fix the card.  If you mistake, do not worry, never brake the card nor VIDA Supreme.  If no sound or no LED light on,  card is not placed in correctly, please check the connector again from checking window.

5.What is benefit of external power supply unit?

Every power transformer is emitting induction noise and vibration. To eliminate those noise, power transformer should be placed far from amplifier. Phono stage amplifier is handling very small signal and x2000 gain, so very sensitive to those noise. External PSU is the best solution to make quiet amplifier.
