Whest ps.30r

I have to say that I am highly skeptical of these claims that using a MAC HC power cord makes a "huge difference" in the performance of a Whest phono stage. I have a Whest PS.30RDT. Folks, this is a 20W appliance. I find it hard to believe that really you need 10 guage wire to supply power to such a low power device. I have my unit configured at 60dB gain to output about 0.6V to the pre-amplifier.

Other than that, I agree with the comments about the Whest PS.30RDT. I don't know about the sound relative to the Whest PS.30, but the Whest PS.30RDT produces a nice 3-dimensional soundstage, reproduces considerable detail, good bass reproduction and produces a clear, if not somewhat "sweet" sound (at least to my ears).

I would caution you on "audiophile" reviews because these days they are generally not impartial reviews. One problem with evaluating phono stages (and equipment in general) is that you rarely get an apples-to-apples comparison. When it comes to phono stages, there are differences in gain and load resistance levels among different models that can result in slightly different sound perceptions. So while I personally like the Whest unit that I own, I hesitate to make claims that it sounds better than other units because in reality things are often so close (in terms of sound) and the ability to make truly scientific comparisons is so limited that if you find a unit that sounds good to you, then you are most (if not practically all) of the way there.

Gents. I have travelled the road from PS.20 to PS.30RDT (missed out the plain vanilla PS.30) and have now lived with the latest PS.30RDT 'Special Edition' for the past nonth or so. My requirement was for a very quiet mc phono stage to use with my Transfiguration Orpheus L (0.3mV output). The SE uses a new discrete bipolar module, ClarityCaps, a reworked power supply and updated RIAA filter capacitors. Having put some hours on the clock since purchase and settling on 65db gain and 220Ohms resistor setting for feeding my Karan Reference MkII preamp, I can honestly say that the designer, James Henriott, has kept all the previous atributes of the PS.30RDT and has produced a phono stage that also has that elusive valve-like organic structure but without the noise pitfalls. I use MIT Oracle MA interconnects and a screened 20A copper MusicWorks ReCoil mains cable customised with Furutech FI-50 IEC and UK mains plug.

To Crystalref:

Could you provide some insights into how the operation of the PS.30RDT SE differs from that of the PS.30RDT? The statements on the Whest website don't really help me understand what is different about the operation of the PS.30rdt se that explains the 70% increase in audio reproduction relative to the ps.30rdt that is claimed on the Whest website (in fact, I really don't understand how that improvement figure was arrived at).

The photographs that you posted of the PS.30RDT SE circuit board were helpful. What was apparent is that the opamp circuits on the PS.30RDT board was replaced by these black boxes (which I presume are the discrete circuitry modules). I also appeared that the input capacitors in the PS.30RDT circuit board are replaced with large Clarity Cap capacitors.

Does the PS.30RDT SE provide more high end gain than does the PS.30RDT? In your case, 65 dB for a 0.3mv cartridge looks to me to be about right, but for a low output cartridge (for example 0.1mv), while 72 dB gain is adequate, I think that a gain level of more like 75 dB would be better.

With regard to my earlier question about the gain levels produced by the Whest PS.30RDT SE, I found the answer by looking at the photos that you posted on the Internet. In the PS.30RDT SE, the gain and resistance load levels are printed on the back panel. The high gain level remains at 72 dB but in the PS.30RDT SE, the low gain level is increased from 40 dB to 43 dB (which means that the Whest PS.30RDT SE will probably work a little better with lower output MM cartridges). It is also worth noting that the load resistance levels listed on the back panel of the PS.30RDT SE are correct, where the user manual has an error.

What do you think about having the access panel to the DIP switches on the underside of the case in the Whest PS.30RDT SE? I appreciate that Whest was responding to complaints about having to open the lid to set the switches, but what I don't like about the underside access scheme is that you have to turn the entire unit over to set the switches. I especially don't like having to handle the case because the casework is very prone to being smudged by fingerprints.

I can't really help you with the claims made by the manufacturer of a 70% improvement! This may be just marketing speak!. What I do know, having lived with the RDT and RDT 'SE' models is that the 'SE' is a substantial improvement sonically. The issue of acessing the DIP switches is only really pertinant if you swap cartridges alot. I don't. Apart from experimenting with load and gain for my Orpheus L when I first got the 'SE' home, I no longer have to access them. I have found that if you slide the phono stage forward from the rack and undo the two Allen bolts (way better than having to remove the unit entirely to undo NINE Allen bolts on the lid!!) to reveal the DIP switches, with the aide of a small mirror, you can make any adjustment you like easily without having to upend the unit. Whest advise and I can concur, that fingerprints/smudges can be easily removed by applying a small amount of WD40 to a clean lint-free cloth and running the cloth along the grain.
