Διατιθεται ηδη απο την εδω αντιπροσωπεια το λαμπατο Phono Stage της Γερμανικης Audio Valve με την ονομασια Sunilda. Προκειται για ενα απο τα καλυτερα phono stages με Διθυραμβικες κριτικες στον Διεθνη Ειδικο Τυπο, το οποιο παρεχει τη δυνατοτητα μεσω ριθμιστικων στην προσοψη του , να το προσαρμοζει ο χρηστης σε ΟΠΟΙΑΔΗΠΟΤΕ κεφαλη , κατα τη διαρκεια της λειτουργειας του ( σε πραγματικο χρονο ) καθως επισης και τη συνδεση δυο κεφαλων/βραχιονων παραλληλα ( διπλο Phono Stage ). Aξιχει να αναφερθει οτι εχει ΕΞΩΤΕΡΙΚΟ τροφοδοτικο και το βαρος του ειναι περι τα 20KG !!
Sundila is a three stage phono-preamplifier, based on 6922 (ECC88) and12AX7 (ECC83) frame grid tubes, suitable for MM- and MC-cartridges. Independently for the two phono inputs, impedance and capacitive load can be set separately and 'on-the -fly' while listening. Thus the user can easily configure the unit to match the features of the cartridge by selecting the optimal input resistance and capacitance for each input separately!
Switches are found for: MM/MC mode for each input; input 1 or 2; selectors are used to select different R and C loads.
two selector knops for each input capacitive and resistor load
In MM mode the gain will be 20 dB lower than MC and at a fixed input-impedance of 47 K.
In MC mode the preamp will have higher gain and switchable input resistors and condensers. The RIAA de-emphasis is passive and split between the first and second stage. Dividing the RIAA network over two amplification stages lowers the insertion losses of the passive network dramatically .Furthermore, the design holds a total absence of feedback, thus increasing the overall dynamics.

Power supplies are solid state regulated. This is the best way to obtain a low noise and supply line with a very low impedance that will increase the performance in the lower frequency range. The power transformer is housed in a separate aluminum case.

Sunilda comes in an lasercut, 4 mm thick steel, chassis in black or silver finish and has a case similar to the Eklipse lineamplifier.
