ps.30r
Already being hailed as one of the very best phonostages ever, the PS.30R is taking the world by storm. Based entirely on the Whest Audio MC REF V platform, the new PS.30R is set to become the NEW STANDARD in the sub-£5000 category. Imagine the resolution power of a £5,000 phonostage in a £1,600 package. This is what the design criterion was for the design engineering team at Whest Audio. The only way to achieve this type of performance was to scale down a true reference, so the MC REF V was used as the platform.
Where the MC REF V uses what the design team call a 'buried discrete' differential input stage to achieve it's ultra low noise 1.2nV sqHz input stage noise level, the PS.30R uses an ultra low noise bipolar 'matched' input stage to achieve it's vanishingly low 1.0nV sqHz input stage noise level. This means that even using an MC cartridge like the Audionote Kondo IO-J with it's 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 it's accuracy and, more importantly, it's transparency. The output stage in the PS.30R was developed for the MC REF V and is used in it's fullest glory in the PS.30R 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.30R 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.30R 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 it’s hand built and assembled in the UK!
