    DAP 10

    So…. firstly, we need to realise that whatever the red book says about what happens above 20Khz in CD playback or any digital playback come to think of it DOES NOT apply to the output stage electronics and also assumes ideal conditions. In addition, signals above 20Khz are as important as the audible range when it comes to playback as it is a KNOWN fact that many musical instruments have their ‘signature’ above 20Khz and we are now finding out by the use of wider bandwidth electronics and super-tweeters that content above 20Khz is important for accurate low frequency playback.
    The red book says all sorts of things… so why do all CD players sound different!
    Why discrete?
    As a designer, I do not use integrated chips or operational amps unless I really have to, and usually that is because of cost. It is pretty well known that although ICs can give great distortion, linearity and bandwidth figures, the sound quality/resolution issue is enough to say ‘stay away’. I therefore prefer to design using fully discrete technology. The PS.20 phonostage is a great example of the above.
    Back to the DAP.10.
    Having worked in the ‘pro’ field for a number of years, both in recording live and in various studios, I am fortunate to have been exposed to the processes that occur before the CD is pressed.
    Anyone who has been in a recording studio control room (not a friend’s converted bedroom or barn!) whilst a session is being recorded would have hopefully noticed a few major differences between what they were listening to and what a high quality domestic audio system sounds like.
    One major difference is image stability, focus and weight. Some audiophiles may think these factors are irrelevant and not part of the music BUT they are every part of what is on the CD and a system that is lacking in these three elements may has a phase/frequency related problem.
    The other is resolution and soundstaging. Again very much part of the recorded material and exists on the playback format and is as important as the music itself for high quality playback.
    The majority of domestic high quality CD playback systems DO suffer from a lack of all of the above.
    What we at Whest Audio realised about 4 or so years ago was that the CD players we tested all suffered from the same inherent problems: Poor image stability, focus, weight, resolution and soundstaging when compared to proaudio analog magnetic tape playback. We looked at what the CD playback output looked like using ‘single tone bursts’ as well as ‘multiple frequency’ and lastly plain old music.
    What we found after much analysis using bespoke software and measuring techniques was that all the players tested (ranging from US$1,000 to US$6,000) exhibited a series of small peaks across a 110Khz bandwidth above 30Khz. These peaks also produced a set of ‘time-shifted’ peaks. These peaks are not music related but seem to be ‘triggered’ with by a full bandwidth signal.
    The small time-shift causes minute ripples in the domain above 30Khz, possibly by ‘beat interaction’ which later finds their way down to the ‘audible’ domain. These ‘ripples’ we believe have a profoundly negative effect on CD reproduction. What the DAP.10 does is effectively stop the ripples from occurring, thus cleaning up the audible domain. We selected a few of the peaks and by applying a very small correction we can re-align the time-shifted information . It took quite a few months before we arrived at a selection of peaks that once corrected made a substantial improvement to the audible domain. The reduction in ripple artefact post DAP.10 is quite staggering and can be heard in an overall improvement of CD playback resolution, soundstaging, apparent bandwidth, focus and stability. All DAP.10 owners have commented on the extra low frequency extension and far better separation of instruments in a bigger soundstage.
    What causes the problem that the DAP.10 corrects is an unknown at this stage but we are researching in to it. I suppose the majority of high-end audio reproduction is R&D as most designers will say.
    Thus DAP.10 does not interfere with the inherent audio quality of the system it is connect to. The systems audio signature isn’t touch in the slightest but what is does do is allow the system to:
    1. resolve much more information
    2. increase apparent bandwidth at both ends
    3. increase soundstage width and depth
    4. increase image stability, focus and weight
    The DAP.10 will quite happily sit along side a $1500 CD player and allow it to outperform a CD player costing 3 times the price! or connected to a High-End unit making it ultra-high end!

    Based entirely on the famed PS.20 the new entry level whestTWO utilizes approx 90% of the former’s electronic design but with a twist, which is about 10% of the MC REF V. Yes, during the design stages of the whestTWO we made a mad decision to incorporate some of the MC REF V ideas, namely it’s hybrid active/passive RIAA filter stage. Unlike other units at this price point that use the standard ‘input-Passive RIAA filter-output’ configuration, the whestTWO uses an identical configuration which was borrowed from the MC REF V and this can also be found in the PS.30R. This new RIAA configuration along with the high-current output stage means the whestTWO can resolve much more information compared to any of its rivals.
    With it's tremendously gorgeous top end, it's hard to beat this phono stage for the money.

    Whest Two Phonostage Features:

     Full Dual-Mono configuration.
    2 Box layout with separate multiple voltage and high current power supply.
    Ultra low noise input with a frequency response of 1Hz-100KHz.
    RIAA curve accuracy to within 0.2dB.
    RIAA extension to 50kHz for better definition and ambience.
    Hybrid filter configuration.
    High current, Class-A discrete output stage.
    Fully variable cartridge gain and loading via internal dil switch.

    Already being hailed as one of the very best phonostages ever, the PS.30R is taking the world by storm. 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!

    If there was ever a product that could upset the apple cart….this is it!  Priced at approx £7000  the MC REF V is a tour de force to be reckoned with.
    The all new circuitry developed for the MC REF V Reference phonostage was first started in 2001 and put ‘on hold’ while the PS.20 was under development.
    The MC REF V Reference phonostage is a departure from the current way of looking at signal integrity and the power supply’s behaviour on the signal.  Where most others will use very exotic components to try to achieve a decent sound, we at Whest Audio have designed, from the ground up, a RIAA playback system using radical audio principles plus some of our own R&D ideas amassed over the years.
    The result is extraordinary audio reproduction.
    Like the PS.30R, the MC REF V lets you listen to music with extreme amounts of detail without the phonostage getting in the way.  PLUS the resolution capability of the MC REF V is about 10 times more than the PS.30R!  Instruments come to life like no other phonostage and their images just hang in the soundstage with absolute solidity and with space that brings a whole new dimension to vinyl.
    The R&D gained from the MC REF V has already been implemented in the design of the entry level whestTWO and PS.30R phonostages.
