Well now, if we can just agree that you are not hearing DC, and now you claim that this 137 mA or whatever is causing this buzz you are wrong. It is that glitch in the sine wave doing it.

IF they have a coil input pi filter, this not only can take everything out of 20 KHz completely out. With the coil input it then unloads the amp from the current needed to drive the tweeters with distortion and whatever. Cutting off the harmonics, maybe it made the distortion more tolerable as they tapped into that "unlimited power". > > Without batteries, being only slightly larger in width than the banana connector set, there seriously can't be much on there.

I do not know their return policy. Look it up. I was having a hard time getting a price on them, so I gave up. If you don't tell me what it costs, I am not buying it.

There is an optimum pF load for those cartridges and that causes a resonance in the higher frequencies that is chosen by the manufacturer to give it their "sound" or whatever. I know my good AT sounded quite a bit different on different stereos, and turntables. It went up to 30 KHz so I would assume it would need lower capacitance cables. > > I will capitulate all that.

Just fit a suitable diode in line with something that is resistive and draws a few amps - like a heater or hot air gun. The load current of the heater will reduce the voltage peaks on one polarity by a volt or so - creating an average offset of about 0.5V. Most toroidal supply transformers powered from the same AC outlet will now hum audibly. Some regular types will do the same, long as in each case they have ratings of 200VA or more and are unloaded or only lightly loaded. If you can monitor the AC current being drawn by the transformer on a scope - you will see the waveform is large and very asymmetrical. In a bad case, the additional current in the primary approaches the maximum rated primary current for the transformer. This article give more detail and a simple fix for the problem. http://sound.whsites.net/articles/xfmr-dc.htm .... Phil Audible hum from AC supply transformers

I know my good AT sounded quite a bit different on different stereos, and turntables. It went up to 30 KHz so I would assume it would need lower capacitance cables. The issue of interfacing the pick-up to the turntable and to the amplifier has been known for decades. The QUAD QC 22 preamplifier introduced in 1959 had a tube socket like connector in the back, intended for plugging in a passive phono module, consisting of resistors and capacitors, it was intended for trimming the load capacitance as well as fine tuning the RIAA equalizer. There were different modules for different cartridges, so if you had to swap the cartridge, you could also swap the equalizer module on QUAD 22.. BTW, ask any audiophool if they have ever been in a symphony orchestra concert and where they were seated :-) Have a brandy during the intermission and the rest of the performance sounds even better :-) . You can also buy a lot concert tickets and brandy for the price of audiophool products.

Even the rich mentally ill. You might gain $6800 selling a botique IEC cable, but you will have certainly sold your soul. ;-)
