Tony IF it is for real, it is a very old product. Certainly not too sophisticated by today's standards. Alex

Unusual that it uses resistors instead of carbon track

I have always had a problem with "steppers" as a volume pot even though the protential for better performance has always been touted because for me they never give me EXACTLY the level I want being click stop points rather than continuous rotation even though I KNOW there are problems with any continuous rotation volum pot in the lower end of pot travel left/right tracking (easily avoided by NOT using it down there ;D ). Course adjustments though,such as left/right balance trim or pre-volume pads I find the idea perfect. Also.I have not yet read a single report ANYWHERE on what happens when it being a mechanical device wear and tear begins to show up as either a noisy switch or one that becomes unreliable which anything,including a more traditional potetentiometer WILL do at some point with me thinking the repair will be either very much a pain in the ass to accomplish OR very expensive if replaced.something not a problem with most pots that are both less expensive and a simple 3-Wire solder-in deal. that anything mechanical in nature will last forever is just not possible so something to consider when making control choices with me choosing sealed always and if a switch both sealed and self wiping for best reliability over time. BTW-The first steppers seemed to have appeared in Western electric audio equipment around 1940 something as did the TVC

Rick Sounds like your listening system isn't quite good enough to realise the extra benefits that a high quality attenuator such as the Danish DACT2 brings. If your system already has a really good S/N, WIDE bandwidth, and VERY high channel separation, the benefits of extra bandwidth and pin point positioning, as well as very low level detail sounding cleaner, are immediately obvious after installing such an attenuator. Alex P.S. I know that we are never going to agree here. You love your audio transformers and vacuum tubes, I don't like them. Simple ! All the dredging up of ancient reviews extolling their virtues isn't going to sway my opinions either .

Pin point positioning ? More about left right balance than it is anything else with a stepper having as little to do with it as "luck" unless your system is dead matched from input source to output transducer with that being so unlikely just not possible without some means of balancing the two channels or EXTENSIVE modification of every single part in the audio path. i agree a stepper will not make it worse but is not a silver bullet making everything else somehow within the limits of human hearing in the left-right perfect match realm. L/R matching=Image width Circuit implementation=image depth Topology choice usually determines bloom and air,that is if the signal is a very nice "detailed" two dimensional sound or sounds like a human performance of music As if I give a shit ? I post for general consumption on what works for ME from a perspective of almost forty years of trial and error in home audio playback and could not care less who agrees or does not it being MY opinion and no more. As for convincing ANYONE of ANYTHING,again for the cheap seats-I really don't give a shit what anyone does or does not do on any level until or unless it has a direct bearing on me or mine and especially so what they choose to listen to which is soooo far down the list of what is important as to be off list entirely cheers

;D Rick That's the way it should be ! If you are happy with your personal choices, that's all that really matters. BTW, I use 1% MF resistors for all locations except where higher power rated resistors are required. For resistors in the differential pairs and NFB networks etc, I always use matched resistors for that location in each channel, chosen not for absolute accuracy, but as close as possible measured resistance. The topologies used seem to negate most of the advantages of boutique components. That's not to say that I wouldn't fit higher quality MFs if I had them readily available.( Stuff the Blackgates though!) I also match transistors in both channels as closely as possible. But I would be surprised if you don't do similar with your choice of components too ! Alex P.S. PSU Impedance has a greater bearing on image separation and image depth than most people realise.

Rick Even with the big "hearing aids" you are wasting your time if you are using a single full range driver in your speakers ! Alex

Jeanne O. Garrido, of West Palm Beach, Florida, was awarded a patent in 1957 for this hearing aid device designed for use in beauty parlor hair dryers. The ear trumpet was to be worn under a hair net during the hair drying process in order to "by-pass the loud roar of the dryer and admit normal sounds present in the room including music and voices at the normal conversational level."
