Whest Audio PS.40RDT and PS.40RDT Special Edition Phono Stage
The essential elements that make the Whest Audio phono stages world-renowned and loved are still retained in the 40 Series but the departure from the 30 Series starts right here.
The 40 Series adds several layers of extra dimensional 'space' with greater instrument-harmonic resolution, 'life like' musicality and a 'microscopic type' of focus that the 30 Series electronics was incapable of. The only way we found we could achieve this was to borrow much of the technology and ideas from the TITAN Pro which was designed to be the very best single box phono stage in the world, which it has accomplished, so we felt ‘why not just scale it down’ and use the essential parts to bring the TITAN Pro’s high-resolution sound to a market place that REALLY needs it.
The new 40 Series pushes the boundaries of what is capable at this price level. No other phono stage in the world at this price range has the abilities of the 40 Series thanks to its BIG brother.
Starting with the chassis w430mm x d290mm x h78mm - is manufactured using the same precision computer controlled machining technique, hand-welded and finished seams to give it high rigidity as the TITAN Pro and MC REF V MK4. Internally the chassis incorporates the suspension system used in the MC REF V Mk4. The combination of this suspension system and ultra strong chassis means that all unwanted vibrations from airborne or structure sources are very well damped. The 40 Series circuit board uses ultra low impurity copper throughout and its copper weight is twice that used in nearly all audio electronics. Small signal integrity is of the highest importance and with this in mind a new regulator system has been designed and employed for the 40RDT Special Edition. The new discrete input stage for the 40RDT Special Edition is based ENTIRELY on the MC REF V MK4 input stage but has been 'trimmed' for the 40RDT Special Edition. The input stage of the 40RDT uses an ultra low noise/ hand-matched monolithic amplifier. Because all of the major amplifying and filter sections of the 40 Series are channel matched, they are capable of incredible realism.
The hybrid RIAA filters have been kept in the 40 Series design because not only is it used throughout the full Whest Audio range, but in the 40 Series it is now trimmed to a far tighter tolerance for both curve and channel matching. Channel matching now is to within 0.12dB and RIAA curve accuracy to 0.15dB. Both these figures are across a bandwidth with spans from 9Hz and 62KHz. Any non-Whest Audio phono stage would be at least 4-6dB down at these extremes, but having experience in pro-audio, vinyl cutting and mastering means we at Whest Audio know what it takes to get the very best from playing back the vinyl format at al price levels.
Gain and load selection is accessed under the chassis like all Whest Audio phono stages. Maximum gain is 72dB and with the internals’ ultra low noise levels it means you will never be stuck for gain ever again! All units are setup for standard low output moving coil (65dB/100ohms with 91pf of input capacitance) but if you do want to experiment it just takes 30secs to change over.
MM gain is at a very healthy and modern 43dB not the older 1970s standard 40dB like our competitors. This with a total capacitance value of 91pf gives a beautifully flat response from your high performance MM cartridge and an unmatched sublime audio output that can only be achieved from a Whest Audio phono stage. With the PS.40RDT and PS.40RDT Special Edition Whest now have a new standard - no other company in the world designs with this much attention to detail for the end-user.
