A proposito .. quanto sotto e' per Alberto che mi chiedeva lumi sui condensatori usati ...
TECHNICAL
Where the MC REF V uses what the design team call a 'buried discrete' differential input stage to achieve its ultra low noise 1.2nV sqHz input stage noise level, the PS.30RDT uses an ultra low noise bipolar 'matched' input stage to achieve its vanishingly low 1.0nV sqHz input stage noise level. This means that even using an MC cartridge like the Audionote Kondo IO-J with its ultra low output level of just 0.15mV, is no problem for the PS.30R. At 72dB you'll have all the gain you need with absolutely no noise.
The 'hybrid' passive/active RIAA filter has been lifted directly from the MC REF V and used for its accuracy and, more importantly, its transparency. The output stage in the PS.30RDT was developed for the MC REF V and is used in its fullest glory in the PS.30RDT to bring unprecedented levels of detail from the lowest harmonics to the highest levels of the frequency band. And because the output stage is totally discrete in design with an output impedance of only 50ohms at 1Khz driving a 600ohm load, it has no problem in driving long lengths of interconnects even if they are of relatively high capacitance!
The PS.30RDT also sports a true balanced output which is a first for a phonostage at this price point! If you run either a fully balanced audio system or broadcast studio you won't be left in the dark.
And finally, you get all the quality you expect from a Reference Whest Audio product at a non-Reference price! Because we wanted to make absolutely sure the audio quality from this product should match or better anything in the $5,000 price bracket the PS.30RDT employs Vishay metal film audio specification resistors, EVOX RIFA and Vishay polypropylene film capacitors, in-house hand selected and matched transistors, Panasonic low ESR and low impedance power supply filter capacitors, ultra low ts time rectifier diodes, low noise voltage regulators, ... and the list goes on and on and on. Oh, and its hand built and assembled in the UK!
Transferring your collection to digital? Do remember that the quality of your transfer is directly related to the quality of your turntable/ arm/ cartridge/ phonostage setup. Rubbish in - Rubbish out really does apply here. The whole range of Whest Audio phonostages are used by archiving libraries throughout the world because of their superb audio performance and ultra low noise levels which is essential when converting to digital.
